cavs: Move inline functions only used in one file out of the header
cavs: Move data tables used in only one place to that file
fate: Add a single symbol Ut Video decoder test
vf_hqdn3d: x86 asm
vf_hqdn3d: support 16bit colordepth
avconv: prefer user-forced input framerate when choosing output framerate
