* Use descriptions of libraries from the pkg-config file generation function
* Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser)
* Use "FFmpeg" for ProductName as MSDN says "name of the product with which the
file is distributed" [1].
* Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1].
* Only build the .rc files when --enable-small is not enabled.

Calculate the duration as accurately as possible to improve decoding of samples
where the last frame is smaller than the rest.
Example:
Take lossless-audio/luckynight-partial.tak from the FATE suit and convert it
to TTA muxed into matroska:
ffmpeg -i $(SAMPLES)/lossless-audio/luckynight-partial.tak -c:a tta lucky.mka
The framemd5 output for lucky.mka without this patch:

The duration without this patch was calculated as 418950000000, which is bigger
than uint32_t and as such stored as 2338172288.

Currently, standard tables like AV_CRC_32_IEEE and such are being generated (or

Since we don't check for seek table integrity in the decoder anymore,
check it in the demuxer instead (Only tta files are guaranteed to have
one, and it should be valid there).
Check also for header integrity, since the check done in the decoder
is ignored because matroska doesn't store the header at all.

There are several containers that support adpcm_thp (Also known as Gamecube DSP)
streams, but only thp files contain the coeff table and previous sample inside
each frame.
Some don't even contain previous sample information at all.
This change will make it easier to implement demuxers for said containers
without having to create a new decoder.
