[Cin] Build from git

[Andrea paz]

I tried to compile with all your patches. I removed patch 0052
according to your instructions. The merge of 3 patches failed:

0010 Hopefully fixed dynamic liba52
0011 Cinelerra/Makefile dynamic ...
0020 Beginning of ffmpeg versioned compiled

I skipped these 3 patches and continued the build using --without-thirdparty.
The build failed immediately, I attach the cin5.log.

PS: In your last email you talk about a "patch archive" but I don't
find anything attached.
