Improve cmake build.  Add unittests to cmake build and automatically detect jpeg support. This change was originally generated to support the build of libyuv in naclports: https://chromium.googlesource.com/external/naclports/+/master/ports/libyuv/.  Also add cmake artifacts to .gitignore file.

The 'Any' versions of functions can handle any width now, so remove the check from the calling code. This has 2 advantages - less code, and less overhead in calling function when any function is NOT used. Downside is more code for case where any is used.

Change Any functions that convert 1 to 1 formats, memcpy style, so use C for remainder to allow a minimum width of 1.  This has some advantages - allows function to be used even with SIMD that only allows aligned memory.  Fewer macros, used by more functions.  SIMD is not used unaligned avoiding page/cache split.  No overlap so it can be used in place.  Disadvantage is it will be slower if close to the maximum number of non-SIMD pixels.

Remove unaligned functions, since most function support unaligned memory now.  This reduces complexity and improves performance for unaligned cases because C code can be avoided, and overhead is less.  Downside is old cpus (core2 and earlier) will be slower for aligned memory case. Except mips, which has alignment requirement, but remove unaligned variant.
