a2efd3ac7a Rewrite unwind thread handling.
This new version doesn't require any specialized thread
implementation, it uses the Current implementation to do its job.
In addition, it runs much faster when multiple threads are trying
to unwind at the same time since the global signal lock is held for
only a small amount of time. Even running through the threads one at
a time should be faster since it no longer requires two passes through
the unwound stacks.

The new code now allows multiple simultaneous unwinds of the
same thread.

Finally, add the ability to unwind from a ucontext_t passed in. This
functionality doesn't work for remote unwinds yet.

e296091060 Create an UnwindMapLocal object.
The way libunwind handles local unwinds is different from remote unwinds,
so create a new map object to handle the differences.

Add new test to verify the map data is being generated correctly.

Add new tests to check for leaks.

Refactor the BACK_LOGW code into a single header file.
