johnmccutchan@google.com 919dc2d6eb * 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.

The fuzzing is not as systematic as for some of the other

turnidge@google.com 8c64adf13e Deal with unhandled exceptions the same way in all Dart api functions. 
--

Terminology change: invalid handles are now called error handles.

Unhandled exceptions used to be a kind of valid handle.  Now they are
a kind of error handle.

For the Dart_Invoke* functions, this means that the standard
error-checking blob drops from two tests to one test and is
harder to mess up.

Many other Dart api functions (Dart_ToString, for example) previously
dealt with unhandled exceptions by turning them into terse error
messages.  Now these functions preserve information about the
exceptions and generate better error messages.

Changed Dart_HandleMessage to return success/failure.  It seemed to fit.

--

Details:

Dart_IsValid becomes Dart_IsError (negated sense).

Dart_GetError now knows how to print a stack trace semi-nicely.

Dart_ExceptionOccurred -> Dart_IsUnhandledException.

Renamed ApiFailure class to ApiError to fit better.

ApiError now has a "data" pointer that points to either an error
message string or to an unhandled exception object.

Documentation changes aplenty.

sgjesse@google.com b7485553a2 Fix deadlock in process exit handling 
As glibc allocation routines are not re-entrant avoid calling delete in signal handler.

Instead the message send from the signal handler on process exit contains both the pid and the exit code. The internal _Process object always installs a data handler for the exit message and calls back into C++ to cleanup the resources allocated for running a process.

Changed the ActiveProcess (renamed to ProcessInfo) to form an explicitly linked list.
