Added the following RPCs to the DDS protocol:
- getLogHistoryLength
- setLogHistoryLength
Historical logs will be sent to clients when they connect and subscribe
to the Logging stream for the first time. Current default log history
length is 10,000 messages to support applications with chatty logging at
startup.

- Flips the flag from --nnbd to --no-nnbd so that by default it builds
the NNBD version
- using the --no-nnbd flag results in the SDK being built in a
directory which has the 'Legacy' suffix added to it
(e.g: out/DebugX64Legacy)
- the '--enable-experiment=non-nullable' flag still needs to be passed
in during execution so that CFE runs in that mode. This is different
from the 'null_safety' flag

This should enable strong mode tests to be fully NNBD opted in. At the
same time, legacy tests when run with the experiment off should
hopefully be able to still consume these libraries because they don't
actually use any NNBD features.
To do this, I changed the script that generates the SDK repo's package
config to not put in a language version for any package whose pubspec
has no SDK version. According to language versioning, that means the
package should be considered to be at the "current" version of the SDK
running the code.
In NNBD, that's opted in. With the experiment off, that is (presumably)
"opted out" in the sense that NNBD doesn't exist.
In order to *not* opt in some of the other packages that currently
lack SDK constraints, I put those in and pinned them to "^2.7.0" which
was what the package config script used to implicitly fill in for them.
I see a bunch of other changes in the generated package config too. The
update script probably hasn't been run in a while.

With this change, DDS takes responsibility for service extension
registration via the service protocol in addition to handling service
extension request routing.
Service extensions registered through dart:developer will continue to
be handled by the VM service as those extensions live within the main
Dart process (this functionality already worked before this CL).
This change also includes a version bump for package:json_rpc_2 to pull
in a bug fix required for this change.

Added a private RPC, _yieldControlToDDS, which DDS invokes once
connected to the VM service. Once this method is called, the following
happens:
- The VM service stops accepting new web socket requests.
- The VM service enters single client mode, where DDS is the single
client.
DDS can only place the VM service in single client mode when it is the only
VM service client. If other clients are connected, DDS will fail to start and
throw an exception.
The purpose of this change is to simplify state management between the
VM service and DDS. The plan is to delegate the following features to
DDS:
- Service extension management
- Custom client name support
- Isolate resume coordination for multiple clients

Original commit description:
Speed up is achieved by sharing most of the dart code, object store
and class table between isolates in single isolate group. So
instead of bootstrapping isolate from the snapshot, isolate is
initialized by setting pointers to existing data structures already
set up for first isolate, and only few isolate-specific structures (moved
to newly introducted isolate_object_store) are created.
To allow for safe cross-isolate switchable call site, type test cache
mutations additional synchronization via RunWithStoppedMutators(that
relies on safepoints) was added.
Besides switchable call sites, no other mutation to the dart code is
done in AOT, which allows such sharing.

This relands commit ff34fd8110,
but puts tree shaking of write-only fields under the flag which is
disabled by default.
So far tree shaking was removing fields which are not used at all.
This change improves tree shaking of fields so fields
which are only written or used as interface targets can be removed.
The following limitations apply:
* Field is not removed if there is a constant object with that field, as
it may impact identity of constant objects which is an observable
behavior.
* Instance field is not removed if it has a non-trivial initializer as
it may have side-effects when executed by constructors.
* Late final fields are not removed, as writing such fields may have
side-effect.
* When field is removed, we may need to introduce an abstract getter
or abstract setter if field is used as a target of an interface call.
If a field was written, then setter would be non-abstract (but empty).

String.fromEnvironment to get new default values for the named
parameter `defaultValue`. This CL changes usages of these constructors
such that they do not depend on the default value, such that it
becomes a non-breaking change for code in the SDK repo to perform the
change in sdk and in sdk_nnbd.

because it attempts to view a script that doesn't exist. Now, we show a

I also noticed that, for sources without file uris (which in my understanding
is legal in Kernel), the ScriptRefElement displays an empty link that
can't be clicked. Now we show some a fallback text.
