Move ff_ac3_critical_band_size_tab in ac3.c for non-hardcoded tables.
...
This symbol is only ever used to calculate the non-hardcoded tables, so
only enable it in that case, and static to the source unit that uses it.

Remove explicit filename from Doxygen @file commands.
...
Passing an explicit filename to this command is only necessary if the

Change code so it uses 2 adds instead of one FFABS.
...
About 1% faster ff_ac3_bit_alloc_calc_psd on Intel Atom, overall speedup
not measurable though.
Should have a bigger effect on systems without cmov or with very slow cmov.
