Alex Stewart df6e27e13b Fix calculation of Solver::Summary::num_threads_used. 
- Previously we were only bounding num_threads_used based on whether
  CERES_NO_THREADS was defined, meaning that we could erroneously report
  a value larger than the number of threads actually used.

Mike Vitus 27789c0d96 Adds a ThreadPool and a thread-safe ConcurrentQueue. 
This is in preparation for adding support for a C++11 based parallel
for implementation. The code is behind CERES_USE_CXX11_THREADS which
is not exposed to the user yet.

Tested by building with and without CERES_USE_CXX11_THREADS defined
and the tests pass.
