Rename Thread -> OSThread.
It's a collection of static utility methods for primitive operations on OS threads.
Make room in the namespace for upcoming class that will represent all the complex state of a VM thread.

Reduce CPU usage when no isolates need to be profiled (e.g. when an isolate calls readLineSync or sleep the isolate owns the thread but is blocked).
This CL does the following:
- Introduces two new API entry points: Dart_IsolateBlocked and Dart_IsolateUnblocked.
- The thread interrupter thread goes into a deep sleep if no isolates need to be profiled (not scheduled on a thread or are in a blocking call).
- When an isolate unblocks, the thread interrupter thread resumes regular interrupts.
- dart:io readLineSync and sleep mark that they are making a blocking call.
This fixes https://code.google.com/p/dart/issues/detail?id=18126 reducing CPU usage to 0% when waiting for stdin or sleeping.

Fix thread-interrupter shutdown on Windows.
This reworks the ThreadId on Windows to be the tid, and not an open HANDLE.

Add isolate tag-profile model and UI.
Distinction between a Dart Error and a ServiceError/ServiceException.
Better Observatory behaviour when a ServiceError/ServiceExceptions occurs.
Display isolate's sticky error.

Keep list of existing isolates.
List is only updated when isolates are created / destroyed.
ThreadInterrupter now walks list of isolates.
Scheduling an isolate for interrupts is now lockless.
Setting a current isolate is now lockless.
Working on Linux, Mac, and Windows.
Assert that the isolate isn't on two threads at once.

* Introduce ThreadInterrupter which calls a TLS set callback when thread is interrupted.
* Threads can only register and unregister themselves with ThreadInterrupter.
* Profiler is no longer involved in interrupting threads. It's just a callback and the buffer.
* Profiler operates lock free using an atomic operation to reserve sample in sample buffer.
* Linux, Mac, and Windows done.
