[FFmpeg-cvslog] gsm: Move requant_tab table to the gsm tables file

[Diego Biurrun]

ffmpeg | branch: master | Diego Biurrun <diego at biurrun.de> | Sat Jun  4 16:53:54 2016 +0200| [81f769fa129edc51c28285649c2df6da717e718f] | committer: Diego Biurrun

gsm: Move requant_tab table to the gsm tables file

This avoids duplicating the table in the gsm template file.
Also adjust the table type to uint8_t to save space.
