Sam Rawlins efa1c497d6 DAS plugins: Fix "interesting files" glob
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.

Sam Rawlins 74ef6d1740 DAS plugins: Do not run lint rules or warnings unnecessarily
Work towards https://github.com/dart-lang/sdk/issues/61490

When a plugin re-resolves a library [1] via
`AnalysisSessionImpl.getResolvedLibrary`, which calls
`AnalysisDriver.getResolvedLibrary`, eventually we get down to
`LibraryAnalyzer.analyze`. This method contains the singular piece of
code that checks `AnalysisOptions.lint` and `AnalysisOptions.warning` [2].

A plugin re-resolves a library in order to parse the code, and ultimately resolve the library into a LibraryElement. It does _not_ use
any lint computed by `LibraryAnalyzer.analyze()`, nor any warnings, nor even any compile-time errors. So we should do our best to do the minimal amount of work that still gets us our LibraryElement.

Setting `AnalysisOptions.lint` and `AnalysisOptions.warning` reduces the
amount of work that `LibraryAnalyzer.analyze()` does.

Sam Rawlins c667238efd DAS plugins: analyze and report diagnostics in parts
Fixes https://github.com/dart-lang/sdk/issues/61449

The previous code, sure enough, only created a DiagnosticReporter for
the defining unit, and only visited the main unit.

The fix is to create a DiagnosticListener for each unit, set the
DiagnosticReporters correctly and the "current unit" as we go, and then
pull the reported diagnostics from each listener.

Sam Rawlins 438b560e44 analyzer: Dismantle legacy 'linter.dart' library
This library mostly exports _public_ API, and the to-be-deprecated
NodeLintRegistry class. So we just move private RuleContext classes
into a new library, and remove the exports.

The lint rules then are adjusted, mostly just renaming
NodeLintRegistry -> RuleVisitorRegistry. But also, this removes a lot
of implementation imports; most rules now have _no_ private imports!

Danny Tuppeny 784fdb4a1f [analysis_server] Move EOL from ChangeBuilder to FileEditBuilder
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).

Sam Rawlins c1c62259e7 DAS plugins: Support configurable severity
This introduces a concept of a "configured severity," based on the
design at https://github.com/dart-lang/sdk/issues/57034, such that
an analysis rule can be configured in analysis options to be one of:
"disable," "enable," "info," "warning," or "error."

We actually don't have any validation of what is inside a plugin
section in analysis options; that should come next.

Sam Rawlins 1091aed650 DAS: only attempt to compute fixes for fix-supporting producers
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`.

Sam Rawlins 41ac971d8a analyzer: rename Lint*Context classes
For the analyzer plugin APIs, these classes should not have the word
'Lint' in them, as they are used for all analysis rules, whether they
report lints or warnings.

* LinterContext                    -> RuleContext
* LinterContextWithParsedResults   -> RuleContextWithParsedResults
* LinterContextWithResolvedResults -> RuleContextWithResolvedResults
* LintRuleUnitContext              -> RuleUnitContext

I'm open to better names for these. Some of these suffer from a
chain-of-nouns name (a "RuleUnitContext" is a Context for a Unit for
a Rule). So we could go with "UnitContextForRule" and "ContextForRule"
or other ideas like that.

Only RuleContext and RuleUnitContext will be public API.

Brian Wilkerson 5f75bb8ba2 Replace change builder copying with a transactional model
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
fixes for 10,000 lint violations.

  Before it took an average of 11216.0 ms.
  After it took an average of 4200.2 ms.

Which is about a 62% improvement.

Sam Rawlins abd4e7754c Introduce two subclasses of 'LintRule' for handling multiple lint codes
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."

Brian Wilkerson 5d6dc673dc Make nodeCovering a method on CompilationUnitImpl rather than an extension method
This allows us to traverse the children without needing to create lists.
It also allows us to iterate over lists of nodes more efficiently.

Tested against the script that computes fixes for 10,000 diagnostics,
I'm seeing the following result.

  Before this CL the average time was 10692.4 ms.
  After this CL the average time was 1900.0 ms.

That's just over an 82% improvement.

Jens Johansen cddee72854 [analyzer] Don't find the same "fixes for all" multiple times
Before this CL, if one has a file like

```
Map<String, String> foo = {
  "1": "1",
  "2": "2",
  "3": "3",
[...]
```

with many violations of the prefer_single_quotes lint, using VSCode and
selecting all would lock up the analysis server, e.g. in
https://dart-review.googlesource.com/c/sdk/+/425503 I showed 400 such
lines taking ~36 seconds on my machine (and 800 such lines taking ~247
seconds).

This is because for each error (lint) in range (i.e. all of them) it
calculates fixes for all of them. Once it's done with that it
deduplicates and throws most of the data away again.

This CL instead only calculates the "fixes for all" for each
combination of error-type and generator, skipping lots of work,
making the whole thing be much faster.

In the data send to the client (VSCode in this instance) the
"diagnostics" for
"Convert to single quoted strings everywhere in file"
contains fewer elements (only 1, vs all before), but it's unclear when
(or if) this is used. Note that the "edit"s does contain all, and
applying it still changes all instances.

I now get these runtimes for the select all case (via the benchmark)
(with cpu governor "performance" which likely wasn't the case for
the ~36 seconds and ~247 seconds above, although it doesn't matter
much with these differences):

400: 0.736783
800: 1.502978
1600: 3.704314
3200: 10.701988

To support this feature:

* Remove `DartAssistContextImpl` as it has no differences from
  `DartAssistContext`. Thus the getters `DartAssistContext` are made
  into fields, and all callers now call `DartAssistContext()`.
* Add a top level `computeAssists` function, similar to the top-level
