Field G. Van Zee 22deef2f54 Support alternative gemm implementation sandboxes.
Detail:
- configure:
  - add support for --enable-sandbox=NAME to configure script, where NAME
    is a subdirectory of a new 'sandbox' directory that contains an
    alternative implementation of gemm. (For now, only implementations of
    gemm may be provided via a sandbox.);
  - add support for C++ compiler. C++ compilers are handled in a manner
    similar to that of C compilers, in that a default search order is
    used, and that CXX is searched for first, if the variable is set. In
    practice, the C++ compiler that is selected should correspond to the
    selected C compiler. (Example: If gcc is selected for C, g++ should
    be selected for C++.) The result of the search is output to config.mk
    via build/config.mk.in. NOTE: The use of C++ in BLIS is still
    hypothetical, but may eventually move to being experimental. This
    support was intended only for use of C++ within a gemm sandbox.
- build/config.mk.in:
  - define SANDBOX variable containing sandbox subdirectory name.
- build/bli_config.in:
  - define either of the BLIS_ENABLE_SANDBOX or BLIS_DISABLE_SANDBOX
    macros in bli_config.h.
- common.mk:
  - include makefile fragments that were propagated into the specified
    sandbox subdirectory;
  - generate different CFLAGS for sandboxes, as well as a separate
    CXXFLAGS variable for sandboxes when C++ source files are compiled;
  - isolate into a single location lists of file suffixes for various
    purposes.
  - reorganized/clean up code related to identifying header files and
    paths.
- Makefile:
  - generate object filepaths for and compile source code files found in
    sandbox sub-directory;
  - remove makefile fragments placed in sandbox sub-directory (cleanmk);
  - various other cleanups.
- Added .cc, .cpp, and .cxx to list of suffixes of files to recognize in
  makefile fragments (via build/gen-make-frags/suffix_list).
- Updated blis.h to conditionally #include bli_sandbox.h (via a new file,
  bli_sbox.h), which each sandbox is assumed to use for any type
  definitions and function prototypes it wishes to export out to blis.h.
- Conditionally disable bli_gemmnat() implementation in frame/3 when
  BLIS_ENABLE_SANDBOX is defined.
