The WAVE demuxer returns packets with many blocks per frame, which needs to be
parsed into single blocks. This has a side-effect of fixing the timestamps.

The encoder depends on the common code, so link against it.

The generic ADPCM codes depends on the ADPCM data tables.

This simplifies the decoder so it doesn't have to process an in-packet header
or handle arbitrary-sized packets. It also fixes decoding of files with large
headers.

Instead of using fixed coefficients, the correct way is to calculate the
coefficients using the highpass cutoff frequency from the ADX stream header
and the sample rate.

It is found in some 8svx files (e.g. ones created by SoX).
Currently the decoder reuses the 8svx functions because we already have
handling of a single large planar packet for the compressed 8svx codecs.

The Zork PCM decoder does not decode the 1 sample we have correctly, therefore
the encoder based on the decoder is also incorrect. There is no good reason to
keep the encoder.

Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical
for most codecs, move Bink IDCT into separate context. Get rid of an additional
permutation table while at it since SIMD support for Bink IDCT is unlikely to
be implemented in foreseeable future.
Quantisation tables also have to change type to signed for proper
dequantisation of DCT coefficients.

This checks if the set of selected exponent strategies for all blocks in a
channel are in the frame exponent strategy table, and if so, writes the
table index instead of each strategy. This saves up to 7 bits per channel per
frame, so the overall effect on quality is small.

Calling Make from subdirectories is not supported and config.mak has
multiple inclusion guards anyway, so the top-level include is enough.

Function pointers are used for templated functions instead of needlessly
duplicating many functions.
