Details: - Implemented a new feature called addons, which are similar to sandboxes except that there is no requirement to define gemm or any other particular operation. - Updated configure to accept --enable-addon=<name> or -a <name> syntax for requesting an addon be included within a BLIS build. configure now outputs the list of enabled addons into config.mk. It also outputs the corresponding #include directives for the addons' headers to a new companion to the bli_config.h header file named bli_addon.h. Because addons may wish to make use of existing BLIS types within their own definitions, the addons' headers must be included sometime after that of bli_config.h (which currently is #included before bli_type_defs.h). This is why the #include directives needed to go into a new top-level header file rather than the existing bli_config.h file. - Added a markdown document, docs/Addons.md, to explain addons, how to build with them, and what assumptions their authors should keep in mind as they create them. - Added a gemmlike-like implementation of sandwich gemm called 'gemmd' as an addon in addon/gemmd. The code uses a 'bao_' prefix for local functions, including the user-level object and typed APIs. - Updated .gitignore so that git ignores bli_addon.h files.
