3d7453e056 configure: allow reverse auto-selection of options 
This adds the possibility to set foo_if and foo_if_any variables,
causing foo to be enabled if all/any of the listed options are
enabled.

29b75f0b67 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.

c816d3d042 AAC: Compress codebook tables and optimise sign bit handling 
The codebooks each consist of small number of values repeated in
groups of 2 or 4.  Storing the codebooks as a packed list of 2- or
4-bit indexes into a table reduces their size substantially (from 7.5k
to 1.5k), resulting in less cache pressure.

For the band types with sign bits in the bitstream, storing the number
and position of non-zero codebook values using a few bits avoids
multiple get_bits() calls and floating-point comparisons which gcc
handles miserably.

Some float/int type punning also avoids gcc brain damage.

Overall speedup 20-35% on Cortex-A8, 20% on Core i7.

f3da24c4c3 SIPR: kill variable-length arrays 
Two of these are in fact constant size, so use the constant instead of
a variable in the declarations.  The remaining one is small enough
that always using the maximum size is acceptable.

e1e949026e Split cavlc out of h264.c. 
Seems to speed the code up a little...
The placement of many generic functions between h264.c and h264.h is still open
Currently they are a little randomly placed between them.

2bedc0e854 Move check_intra4x4_pred_mode() back from h264.h to h264.c, the function is just 
called once per MB in worst case and doesnt seem to benefit from static inline.
Actually the code might be a hair faster now (0.1% according to my benchmark but
this could be random noise)
