Use native tags instead of avi ones, simplifies a lot raw video codecs
handling.

This fixes a segfault with samples that I have (both of them MPEG-TS). Looks like
avctx->codec is not being set during parsing.

Resample to the rate that was configured in SDL.

The output AVFrame buffer only has data for the downmix channels.
Fixes a segfault when decoding dca with request_channels == 2.

Solaris defaults to non-standard utilities (grep, sed, ...) with
proper ones being in /usr/xpg4/bin.  Prefixing PATH with this
directory when it exists ensures we get correct variants.

parse_packed_headers() returns either zero or a negative error code
so its return type must be signed.

The 'ret' variable is used for negative error codes so it should
be a signed type.

The code fails to compile and is broken beyond repair.

It is only used in that library.

The table is so small that the space gain is not worth the
performance overhead of cross-library access.

Make av_pix_fmt_descriptors table static on next major bump.

Making the table public is dangerous, since the caller has no way to
know how large it actually is. It also prevents adding new fields to
AVPixFmtDescriptor without a major bump.

This avoids having to overestimate the md5 context size, which
isn't known beforehand, allowing us to use the new allocate functions
instead.

The current API where the plain size is exposed is not of much
use - in most cases it is allocated dynamically anyway.

If allocated e.g. on the stack via an uint8_t array, there's no
guarantee that the struct's members are aligned properly (unless
the array is overallocated and the opaque pointer within it
manually aligned to some unspecified alignment).
