Make service lifecycle checks thread safe
...
RunLoop tests were getting wedged trying to communicate with the vm-isolate that was shutdown before a test isolate started up. dartbug.com/22219
This CL:
* ensures that any 'is the service running' checks are done with a lock held.
* Normalizes trace messages printed from the vm-service.

* Create vm-service isolate at Dart_Initialize time.
...
* Remove Service create callback.
* Simplify creation of service isolate.
* Creation is done on thread pool.
* Use vm-service isolate for loading in standalone embedder.
* Remove import of dart:io from builtin library.
performance changes:
no service isolate:
$ ./tools/test.py -m release
Test configuration: none_vm_release_ia32
[01:27 | 100% | +12363 | - 0]
$ ./tools/test.py -m release
Test configuration: none_vm_release_ia32
[01:27 | 100% | +12363 | - 0]
always start service isolate (as a thread pool task):
$ ./tools/test.py -m release
Test configuration: none_vm_release_ia32
[01:45 | 100% | +12363 | - 0]
$ ./tools/test.py -m release
Test configuration: none_vm_release_ia32
[01:44 | 100% | +12363 | - 0]
service does I/O (calls to Dart_LoadScript block until service is running):
$ ./tools/test.py -m release
Test configuration: none_vm_release_ia32
[01:55 | 100% | +12363 | - 0]
$ ./tools/test.py -m release
Test configuration: none_vm_release_ia32

vmservice: basic object graph serialization.
...
Sends a service event with binary data encoding the basic shape of the object graph; for each object, its:
* size
* class id
* neighbors (excluding smis and nulls)
This is a minimal implementation to make the first unit test pass (TDD).

Reduce service isolate startup time from ~80ms to ~30ms
...
- Get access to dart:io internal signal listening function using API instead of mirrors.
- Service isolate can start with service deactivated.
- Load Observatory front end resources only when service activated.
- Do not execute Dart Service code until service is activated.
- Register live isolates when service is activated.
- Startup refactored to allow for future use of script snapshots.

Add a new event family for GC-related events, and generate an event after each garbage collection with basic stats.
...
One reason for this is to provide a structured alternative to the ad hoc logging format of --verbose_gc, and to move some functionality currently provided by standalone one-off scripts into the observatory.
Add first unit test for events.

Add a VM page to the observatory.
...
Make the VM a ServiceObject. Some refactoring in the ServiceObject
implementation.
IsolateList is no longer a ServiceObject. It should eventually become more like our caches.
Support the /vm request in the vm. Remove isolate list request.
Improvements to Isolate::PrintToJSONStream: always provide a
reasonable name. Use the same code to produce isolate refs and
non-refs.
Improve isolate status message when the isolate is paused at
start/exit. Add a resume link to the isolate view.
Add a navbar to the error page so that dartium users are less likely
to get stuck.
