Devin Matthews 0e1a9821d8 Add configure options and generate bli_config.h automatically.
Options to configure have been added for:
- Setting the internal BLIS and BLAS/CBLAS integer sizes.
- Enabling and disabling the BLAS and CBLAS layers.

Additionally, configure options which require defining macros (the above plus the threading model), write their macros to the automatically-generated bli_config.h file in the top-level build directory. The old bli_config.h files in the config dirs were removed, and any kernel-related macros (SIMD size and alignment etc.) were moved to bli_kernel.h. The Makefiles were also modified to find the new bli_config.h file.

Lastly, support for OMP in clang has been added (closes #56).
