[Cin] latest hacks

[Andrew Randrianasulu]

this time as tar.gz because adding (or downloading) 50+ files a bit of
chore..

based on mainline c0251c4aa075

mostly same old patches for termux + few even older hacks..

Andrea, I broke my cpu_debug patch into 3.

randrik9/0047-Debug-add-printing-of-cpucount-from-ff_cpus.patch
randrik9/0048-Debug-add-cpu-count-printing-for-mwindow.C.patch
randrik9/0049-Hack-raise-cpu-cap-from-8-to-16.patch

can you (and Phyllis) see if just 0049 gives you better result? if possble
please also test non-ffmpeg based MPEG encoding and decoding...
