* Make Benchmark a single header library (but not header-only) This patch refactors benchmark into a single header, to allow for slightly easier usage. The initial reason for the header split was to keep C++ library components from being included by benchmark_api.h, making that part of the library STL agnostic. However this has since changed and there seems to be little reason to separate the reporters from the rest of the library. * Fix internal_macros.h * Remove more references to macros.h
