Set interlaced to false if we don't have an interlaced frame

The function is only used in VP3 and VP5, so no need to have it in
DSPContext.

Expose the current sequence number via an AVOption - this can
be used both for setting the initial sequence number, or for

This saves one instruction in the x86-64 assembly.

This allows us to get rid of them on the next major bump. All of the
above are functionally irrelevant, and most of them are unused, except
the vp3 one, which is used wrongly in the bfin arch optimizations.

This allows us to remove FF_IDCT_WMV2, which serves no practical purpose
other than to be able to select the WMV2 IDCT for MPEG (or vice versa)
and get corrupt output.

Fate tests for all wmv2-related tests change, because (for some obscure
reason) they forced use of the MPEG IDCT. You would get the same changes
previously by not using -idct simple in the fate test (or replacing it
with -idct auto).

The function is unused.

This simplifies the code slightly.

The theoretical minimum for a (not totally well formed) RTCP packet
is 8 bytes, so we shouldn't require 12 bytes as minimum input.

Also return AVERROR_INVALIDDATA instead of 0 if something that is
not a proper packet is given.

This clarifies where the limit number comes from, and only
requires exactly as much padding space as will be needed.

The main difference to the existing suites from RFC 4568 is
that the version with a 32 bit HMAC still uses 80 bit HMAC
for RTCP packets.

The lavf-internal parser functions are used when receiving
mpegts over RTP. This fixes memory leaks in this setup.

The normal mpegts demuxer close function was updated in ec7d0d2e in
2004 to fix leaks, but the parsing function used for RTP wasn't
updated and has been leaking ever since.

libavutil/arm/asm.S sets '.arch' depending on HAVE_ARMV5TE so that
assembling armv5te code will always succeed even if the default -march
flag does not support it. HAVE_ARMV5TE_EXTERNAL tests assembling code
with the default arch.
Fixes the missing symbol ff_prefetch_arm with --cpu= not including
armv5te.

Too much code relies in having init_get_bits fed with a valid
buffer and set its dimension to 0.

Check for NULL buffer instead.

The function is never used.

Conveniently (together with Justin's earlier patches), this makes
our vorbis decoder entirely independent of dsputil.

This is identical to what e.g. vp8 does, and prevents the function call
overhead (plus dependency on dsputil for this particular function).
