Step one towards merging timer changes. This patch cleans up our use of generic macros and also merges changes in the build system. It adds options -DBENCHMARK_ENABLE_TESTING and -DBENCHMARK_ENABLE_SHARED.

Make Benchmark a single header library (but not header-only) (#407) * 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

Fix compilation on Android with GNU STL (#596) * Fix compilation on Android with GNU STL GNU STL in Android NDK lacks string conversion functions from C++11, including std::stoul, std::stoi, and std::stod. This patch reimplements these functions in benchmark:: namespace using C-style equivalents from C++03. * Avoid use of log2 which doesn't exist in Android GNU STL GNU STL in Android NDK lacks log2 function from C99/C++11. This patch replaces their use in the code with double log(double) function.

Disable iOS CPU Frequency readout (#335) * Add macro definition for iOS Add an additional macro definition for iOS. iOS is defined as a Mac OSX invariant in the TargetConditionals include, thus we treat it as a subset of OSX within the defines. * Skip error for hw.cpufrequency on iOS hw.cpufrequency is not available on iOS devices. As there is no way to reliably retrieve the CPU frequency on iOS we are printing out a warning that we were unable to detect the CPU frequency and set it to 0. This only disables cpu frequency readouts on actual physical iOS devices. Running this code on the simulator still gives the cpu architecture of the host computer as the simulator passes down the sysctl calls to OSX.
