Some extra initialization needs to occur before calling the local/remote
GetFunctioneName.
Also, cleanup the test code a bit:
- Make all local functions static.
- Create a common function to create and finish remote processes.
- Remove unused function.
- Fix the formatting a bit by making it match clang format.
Test: Ran the unit tests.

The object hierarchy was confusing and convoluted. This removes
a lot of unnecessary code, and consolidates the BacktraceCurrent
and BacktraceThread code into BacktraceCurrent.

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.

Update to handle the new optimized way that libunwind works.
In addition, a small refactor of the BacktraceMap code.
A few new tests of for good measure.

This includes removing the map_info.c source and replacing it with the
BacktraceMap class to handle all map related code.
Change all callers of libbacktrace map functionality.
Also modify the corkscrew thread code so that it doesn't need to build
the map twice (once in the corkscrew format and once in the libbacktrace
format).

The old code was essentially trying to be C++ in C and was awkward. This
change makes it all objects with a thin layer that C code can use.
There is a C++ backtrace object that is not very useful, this code will
replace it.
This change also includes moving the backtrace test to a gtest, and adding
coverage of all major functionality.
