Christopher Ferris db2309e3d1 Revert enabling libunwind.
It appears that some branches might not have libunwind set up properly.

Christopher Ferris 7f081ec079 Use new defines in test code.
In addition, fix up the warnings and remove the -fpermissive when
compiling.

Christopher Ferris cbfc7302fb Add some clarifying defines.
In order to be explicit in the Backtrace::Create() calls, adding a couple
of defines and some comments to describe what they mean.

Christopher Ferris 8ed46278be More libbacktrace fixes.
Included in minor fix ups is the addition of a warning macro to replace
all of the ALOGW calls.

Fix a race where multiple threads could be attempting to unwind the threads
of the current process at the same time.

Christopher Ferris 17e91d44ed Rewrite libbacktrace using C++.
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.

Christopher Ferris a16a4e10e1 Fix problems in libbacktrace.
- Add a wait for stop to backtrace_test. There is a possible race
  condition that is exposed when using libunwind.
- Fix a few calls to unwind function calls.

Christopher Ferris 7fb22878d4 Create a single backtrace library.
This library will be used to abstract away getting backtrace
data from how it is implemented. This is the first step to
replacing libcorkscrew with libunwind.
