07e982d9b4 Deprecate and undocument the FORCE{MMX|SSE|SSE2|SSE3} flags. These were originally introduced in TurboJPEG/IPP as a way to override the automatic CPU selection in the underlying IPP codec, which was closed source. They are not meaningful anymore, since libjpeg-turbo provides environment variables to accomplish the same thing and since it no longer necessarily uses x86 SIMD code behind the scenes.

9b28defe6a Completely refactored the TurboJPEG C API so that it uses pixel formats instead of the clunky pixel size + flags combination to define the pixel size and component order. tjCompress2() and tjTransform() can also now grow the JPEG buffer as needed, which can allow programs to save memory by not pre-allocating the "worst-case" buffer size calculated by TJBUFSIZE(). Converted API documentation to Doxygen. There is no legacy code remaining, so the refactored version of the library has been re-licensed under a BSD-style license.
