random / rand is slow and impacts performance testing.
Although its only called to clear a frame once, a typical profile shows
it high in the overall profile, when doing 1000 frames for a benchmark.

Replace random is a faster version for unittests.

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.
