[Cin] Compiling Cingg on termux (Linux userspace for Android devices)

Sat May 15 20:40:10 CEST 2021

tried to make more real patches:

$ git format-patch -o randrik/ e04ca4a9e14
randrik/0001-constify-fileffmpeg.C.patch
randrik/0002-ifdef-for-DV.patch
randrik/0003-TERMUX-ifdefs-in-guicast.patch
randrik/0004-libzmpeg-TERMUX-ifdefs.patch
randrik/0005-Add-libzmpeg-ifdef-in-fileac3-move-fireware-objects-.patch
randrik/0006-more-ifdefs-for-file.C-ac3-demand-libzmpeg.patch

note patch0001 re-enables leaking ff->video_probe(), so do not apply
as-is....
0002 should be safe for apply
0003/0004  a bit more involved and adds header for termux compilation
0005/0006 should be safe to apply together
