[Cin] Few patches for thirdparty (mostly for termux compilation)

Sat May 8 15:54:56 CEST 2021

I still can't link properly main cin executable, but coming closer with
just pthread stuff missing and two ac3 symbols:

Even if I manually combined *. o files from libcancelthread.a and
libguicast.a

But along the way I made few patches...

They affect android-specific parts of buildsystem in libaom (upgraded to
3.1.0 release) and libwebp-1.1.0.. Also opus build fails in test_api, I
disabled it..

Ffmpeg-4.4 should be ready to drop in, on termux there were cryptic errors
in aac encoder and hevc and opus (due to B0 being already defined
somewhere) but I hacked those files (renamed B0 to B0_) and whole ffmpeg
was build..

For ffmpeg testing just put official 4.4 tarball in thirdparty/src change
ffmpeg-4.3.0 to ffmpeg-4.4.0 in configure.ac, /autogen.sh and configure & &
make as usual (my configure.ac hack contain other changes)

If you want to test new libaom you can repack it from gz snapshot:

https://aomedia.googlesource.com/aom/+archive/c0f14141bd71414b004dccd66d48b27570299fa3.tar.gz

Be aware it unpacks in current directory, So create some empty
libaom-v3.1.0 and unpack this archive from there....
