396b73c7f7 ac3dec: Remove unneeded context variable, num_cpl_subbands. It is also 
not needed for spectral extension or enhanced coupling since it is
redundant information, so I am removing it from decode_band_structure()
as well.

We need to change decode_line to always_inline because gcc decided not to inline
it anymore once we force some calls to get/put_symbol() to be non inlined and
this decision of gcc would lead to a 10% overall speed loss.

ftp://vqeg.its.bldrdoc.gov/HDTV/SVT_exports/SVT_YUV10_Exports_/NewMobCal_YUV10_720p5994_/
I have called the format v210x due to its similarity to v210, note though I have
not confirmed that v210x is different from actual v210 samples it just is
different from the description of v210 I am aware of.
