This change includes an initial implementation of the new VM service
implementation based on `package:dart_runtime_service`, along with the
necessary plumbing to start it in place of the legacy VM service
implementation.
The entrypoint for the new VM service implementation is located in
dart_runtime_service_vm/bin/vm_service_entrypoint.dart, which is
compiled into AppJIT and AOT snapshots when the
`--include-experimental-vm-service` flag is provided to `build.py`. To run
the VM with the new VM service implementation, the
`--experimental-vm-service` flag must be provided.
Currently, the experimental VM service implementation supports:
- User specified ports
- Authentication code flags
- Enabling the HTTP server via SIGQUIT
- Some service protocol RPCs that don't require an isolate ID (e.g.,
`getVM`)
See go/dart-runtime-services-unification for more details.
