Changes the initialization logic for `PluginConfiguration` so that it
always populates the `diagnosticConfigs` field with a map that ignores
case when matching keys. This insures that diagnostic codes in a
plug-in configuration are matched in a case-insensitive fashion.
Also changes the logic in `pkg/analysis_server_plugin` so that when it
looks up names in this map, it uses `DiagnosticCode.lowerCaseName`
rather than `DiagnosticCode.name`. This in itself has no effect (since
the map ignores case), but it paves the way for deprecating (and
eventually removing) the `DiagnosticCode.name` getter.

Adjusts the logic in the lint `Registry` class so that lint names are
matched in case-insensitive fashion. For the most part this is
accomplished by adding calls to `.toLowerCase()` inside the `Registry`
class, preserving its API.
For the `enabled` method, preserving the API would have been a pain (I
would have had to translate the keys in the `ruleConfigs` parameter to
lower case). So instead I added an assertion to verify that the keys
were lower case, and pushed the responsibility to the callers to
create lower case keys.
This paves the way for a follow-up CL that will translate diagnostic
codes to `lower_snake_case` conventions.
It also solves a longstanding problem with the mixed case lint rules
`no_runtimeType_toString`, `prefer_for_elements_to_map_fromIterable`,
`prefer_iterable_whereType`. Previously, the user had to carefully
imitate the capitalization of the lint rules when specifying them in
the `analysis_options.yaml` file, even though `// ignore:` comments
for the lints matched in case insensitive fashion. With this CL, the
lint rule names in `analysis_options.yaml` are matched in case
insensitive fashion as well.

Prior to this CL, the analyzer's set of unignorable diagnostic code
names (`AnalysisOptionsImpl.unignorableDiagnosticCodeNames`) was
constructed in the following way:
- For each entry in the `cannot-ignore` section of the
`analysis_options.yaml` file that matches the name of a severity
code, the names of all diagnostic codes with matching severities
were added (1).
- All other entries in the `cannot-ignore` section were converted to
upper case and then added (2).
However, diagnostic codes associated with lints are named using
`lower_snake_case`, while analyzer diagnonstic codes are named using
`UPPER_SNAKE_CASE`.
Some of the logic that consumed
`AnalysisOptionsImpl.unignorableDiagnosticCodeNames` didn't account
for this, resulting in some subtle bugs:
- When the resolved correction producer base class
`_BaseIgnoreDiagnostic` attempted to figure out if a diagnostic was
unignorable, it compared elements of
`unignorableDiagnosticCodeNames` to `DiagnosticCode.name`, which
meant that it would successfully recognize non-lint codes as
unignorable, but it would only recognize that a lint code was
unignorable if it was included in `unignorableDiagnosticCodeNames`
by putting the name of a severity in the `cannot-ignore` section of
the `analysis_options.yaml` file.
- When `LibraryAnalyzer._filterIgnoredDiagnostics` attempted to block
unignorable diagnostics from being ignored, it compared elements of
`unignorableDiagnosticCodeNames` to `DiagnosticCode.name`,
`DiagnosticCode.uniqueName`, and
`DiagnosticCode.name.toUpperCase()`. This worked, however the
comparison to `DiagnosticCode.uniqueName` had no effect. Note that
values of `DiagnosticCode.uniqueName` always take the form
`ClassName.snake_case_diagnostic_code` or
`ClassName.SNAKE_CASE_DIAGNOSTIC_CODE`. It's impossible for any of
the values added to
`AnalysisOptionsImpl.unignorableDiagnosticCodeNames` to ever match
this, because (1) always adds values of `DiagnosticCode.name` (which
never contains a `.`), and (2) always adds strings that have been
converted to upper case.
- When `IgnoreValidator.reportErrors` attempted to report unignorable
and duplicate entries, it compared elements of
`unignorableDiagnosticCodeNames` to `IgnoredDiagnosticName.name`,
which is always lower case. That meant that it would only recognize
that a diagnostic code was unignorable if the diagnostic code was
associated with a lint and was included in
`unignorableDiagnosticCodeNames` by putting the name of a severity
in the `cannot-ignore` section of the `analysis_options.yaml`
file. (Note, however, that this bug was unobservable because the
reporting of the `unignorable_ignore` diagnostic is currently
disabled; I will address this in a follow-up CL.)
- Additionally, the logic to populate
`AnalysisOptionsImpl.unignorableDiagnosticCodeNames` based on a
severity code had a bug in its handling of error processors: if one
or more error processors were used to change the severity of a
diagnostic, then entries would be added to
`AnalysisOptionsImpl.unignorableDiagnosticCodeNames` corresponding
to both the original and the new severity.
These buggy behaviors have been fixed by:
- Streamlining and simplifying the logic that builds
`AnalysisOptionsImpl.unignorableDiagnosticCodeNames`, and ensuring
that all strings added to it are all lower case.
- Changing all logic that checks whether a string is contained in
`AnalysisOptionsImpl.unignorableDiagnosticCodeNames` so that it
first converts that string to lower case.
- Removing the ineffective logic in
`LibraryAnalyzer._filterIgnoredDiagnostics` that attempted to
compare elements of `unignorableDiagnosticCodeNames` to
`DiagnosticCode.uniqueName`.

Currently, diagnostic codes associated with lints are named using
`lower_snake_case`, while analyzer diagnonstic codes are named using
`UPPER_SNAKE_CASE`.
However, when the analyzer builds instances of the `ErrorProcessor`
class, it always uses `UPPER_SNAKE_CASE` names.
Some pieces of logic that matched up `ErrorProcessor`s to diagnostic
codes accounted for this difference; others didn't.
This led to a some buggy behaviors:
- If an instance of `ErrorProcessor` got constructed outside of the
analyzer (by an analyzer client using the analyzer public API), and
it supplied a `lower_snake_case` name, then
`ErrorProcessor.appliesTo` would only successfully match if the name
referred to a lint.
- The resolved correction producer base class `_BaseIgnoreDiagnostic`
(which forms the basis for the quick fixes "Ignore '...' in
`analysis_options.yaml`", "Ignore '...' for this line", and "Ignore
'...' for the whole file") would only notice that a diagnostic was
unignorable if the case matched exactly. In practice, this meant
that when operating on instances of `ErrorProcessor` created by the
analyzer, it wouldn't properly handle lints.
These buggy behaviors have been fixed by:
- Changing the `ErrorProcessor` constructor to always convert the
`code` to lower case.
- Changing all references to `ErrorProcessor.code` to assume lower
case.

No more flag, always parse into the new AST, always visit new AST nodes,

This is still de jure a breaking change, because `parent` of deprecated

Replaces "is" tests that refer to classes derived from
`DiagnosticCode` with tests on `DiagnosticCode.type`:
- `x is ScannerErrorCode || x is ParserErrorCode` is replaced with
`x.type == DiagnosticType.SYNTACTIC_ERROR`. This is exactly
equivalent, because `ScannerErrorCode` and `ParserErrorCode` are the
only two `DiagnosticCode`-derived classes whose `type` method returns
`SYNTACTIC_ERROR`.
- `x is TodoCode` is replaced with `x.type ==
DiagnosticType.TODO`. This is exactly equivalent, because `TodoCode`
is the only `DiagnosticCode`-derived class whose `type` method
returns `TODO`.
- In `statement_completion.dart`, `x is! HintCode && x is!
WarningCode` is replaced with `x.type ==
DiagnosticType.SYNTACTIC_ERROR`. The new test is less accepting: for
example, it previously accepted diagnostics of type
`StaticWarningCode`. This test is used to short-cut the generation
of statement completions such as completing an incomplete `do`
statement. These completions are only necessary to generate if there
is a syntax error, so there should be no user-visible behavior
change.
- In `fix_processor.dart`, `x is LintCode || x is HintCode || x is
WarningCode` is replaced with `x.type == DiagnosticType.LINT ||
x.type == DiagnosticType.STATIC_WARNING`. The new test is more
accepting: it now accepts any diagnostic code whose type is
`STATIC_WARNING`, when previously it only accepted warnings of type
`WarningCode` (and rejected warnings of types like
`StaticWarningCode`). This test determines when quick fixes like
"ignore diagnostic on this line" are offered, so the behavior change
is appropriate.
- Also replaces a documentation reference to `TodoCode` (in
`todo_codes.dart`) with a reference to `DiagnosticType.TODO`.
These changes pave the way for a follow-up CL in which I plan to
eliminate these derived classes entirely.

In testing, I saw that _added_ files were not being analyzed at all by
plugins. It turned out that `PluginManager.broadcastWatchEvent` uses
that glob to decide if watch events should be broadcast to a given
plugin isolate. It uses this Glob to determine that answer:
```dart
Glob(
_resourceProvider.pathContext.separator,
pattern,
).matches(filePath)
```
and using `'*.dart'` for that pattern, always answers "no, this file
does not match '*.dart'"; I believe `**.dart` is the correct glob
pattern we should use.

Because ChangeBuilder can be used to modify multiple files, the EOL should come from an individual files edit builder and not from the overall ChangeBuilder.
This change renames `eol` on ChangeBuilder to `defaultEol` (since it's still useful to supply a custom default, for example when moving a class from an existing file to a new file, we want to default to the same EOL as the source file), and adds an EOL to file edit builders which is computed from the file content (and falls back to the default from ChangeBuilder if there are none).
My intention here is to not introduce any breaking changes (yet) so the ChangeBuilder constructor interface still has the "eol" named parameter (marked as deprecated) as well as the new `defaultEol` parameter.
I added a new `StringExtension` for `endOfLine` to both analyzer_plugin and analysis_server_plugin as we need this in both places (but I expect one of those projects will ultimately be dropped). This slightly differs from `CorrectionUtils.endOfLine` because it can return `null` which is a signal to fall back to the ChangeBuilder default instead of forcing its own default. (CorrectionUtils.endOfLine now uses that extension, although because of the null/default, it's likely that some - if not all - uses of this should migrate to the new extension and fall back to a default from a ChangeBuilder).

The diff makes this change look bigger than it is.
Here's how the code worked before: `compute()` called `_addFromProducers()`. `_addFromProducers()` had a local function, also
called `compute()`, which is called per CorrectionProducer. The local
`compute()` function would unconditionally create a ChangeBuilder and
call each CorrectionProducer's `compute()` method, then call back out
to an instance method called `_addFixFromBuilder()`, which would drop
the computed change on the floor if `fixKind` was `null`.
This CL contains the following changes to the above system:
* The local `compute()` function and the instance method,
`_addFixFromBuilder()` are combined together, into one instance
method, `_addFromProducer()`.
* Then, the `fixKind` check is moved to the very top of that
method, bailing out _before_ computing changes if `fixKind == null`.

Copying change builders in order to enable reverting changes from a
single correction producer when there's an exception is expensive.
This CL replaces that implementation with a transactional model.
Clients are not required to start a transaction (that happens
automatically), but are required to signal the end of a transaction by
invoking either `commit` or `revert`. (Actually, `commit` is assumed
if neither method is invoked before computing the `SourceChange`.)
There is some information in the Dart file edit builder related to
imports that isn't correctly handled. The reason for this is that too
much of the import computation is done up-front. I don't think this
will be a problem in practice (or at least not often), but we should
come back at some point to change the implementation so that we retain
abstract data longer and perform more processing at the very end (where
we'll have complete information and probably be able to do a better
job anyway).
This CL improved the performance of the benchmark that adds and applies

After it took an average of 4200.2 ms.

Before this change, we had an enforcement that either 'get lintCode' or
'get lintCodes' is implemented, but it was a runtime enforcement. And it
was a little roundabout.
The new system is simpler and more typical:
* `AbstractLintRule` is the parent type, and it's sealed. It provides
`get lintCodes` as an interface. Code outside of the lint rules
requires this getter, in registering codes, etc.
* `LintRule` is the new subclass which is the "90% case." It declares
a `get lintRule`, and offers simpler reporting methods for reporting
a single code everywhere.
* `MultiLintRule` is the new subclass which represents that last
"10% case." It only declares the reporting methods which all require
a LintCode parameter, since there is no concept of a "default lint
code among all my lint codes."
