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.

cbracken@google.com a6ace331f3 Replaced strerror() calls with threadsafe strerror_r(). 
Mac/Android use the XSI-compliant definition of strerror_r() which stores the message in the passed-in buffer.

Linux uses the GNU-specific definition of strerror_r() which takes a buffer and returns the message in a char* (which may or may not be the passed-in buffer).

iposva@google.com 48aed26029 Fix bug 6586: 
- Attempt to run the Monitor thread_test multiple times before failing
  due to its potential to failure due to timing.
- Use named constants when converting millis to seconds and nanos.

srdjan@google.com 743c4a4475 Dart's stack size should be the same number of words on ia32 and x64, i.e. it should be twice as large on x64 as on ia32.

asiva@google.com 4027727562 For now set the stack buffer size to 16k (we need to compute this during thread start and store it in the worker object instead of the current scheme of setting this up in HandleMessage). 
Adjust stack size to 512KB as all tests seem to run with that limit.

asiva@google.com c078663643 1. Remove recursion during snapshot writing and reading 
2. set thread stack size to 128k
3. Fix the native message handler to ensure that it works with the new model of not recursively inlining objects.
