1410eeb6ea imc: Use correct position for flcoeffs2 calculation 
flcoeffs2[pos] should be the log2 of flcoeffs1[pos].
flcoeffs1[0] can be 0 here, thus flcoeffs2[pos] gets set to -inf,
causing problems further down.

This seems to have been copied from imc_decode_level_coefficients in
commit 4eb4bb3 without updating the position.

cac4760bf4 iac: generate codec tables as they are supposed to be 
Unlike its predecessor, Indeo Audio codec generates tables depending on
sampling rate. Previously decoder used pre-generated tables for 22050 Hz
which obviously doesn't work with other frequencies.

Many thanks to Maxim Poliakovsky for providing all needed information
for this.

a1e98f198e get_bits: remove A32 variant 
The A32 bitstream reader variant is only used on ARMv5 and for
Prores due to the larger bit cache this decoder requires.

In benchmarks on ARMv5 (Marvell Sheeva) with gcc 4.6, the only
statistically significant difference between ALT and A32 is
a 4% advantage for ALT in FLAC decoding.  There is thus no (longer)
any reason to keep the A32 reader from this point of view.

This patch adds an option to the ALT reader increasing the bit
cache to 32 bits as required by the Prores decoder.  Benchmarking
shows no significant change in speed on Intel i7.  Again, the
A32 reader fails to justify its existence.
