In particular, fix trac ticket #3231.

Simplify logic, avoid multiple unnecessary alloc/free operations.

Fix PTS set on the frame when encoding, which must be specified in the
encoder timebase or this will confuse the encoder.

When muxing the packet, the PTS/DTS generated by the encoder is then
rescaled to the stream timebase.

Avoid the need of tweaking, also show how to get list of supported sample
formats.

untested (noone tested within about a month) and the change is
quite trivial so should be ok. While the code before this change

If the audio changes from 9eac7c43 were merged as they were, this
would cause scripts with both video+audio to fail with a lot of
audio decoding errors (the video would be fine). Scripts with
only one of either video or audio were unaffected. Additionally,
the av_packet changes in general caused seeking to break.

Using av_packet_from_data allows video+audio scripts to work as
expected, without audio decoding errors.  It also fixes seeking.

The header parser uses forward and backward parsing, making the
bulletproof prevention of loops difficult, thus this simple
detection code.
If someone improves the forward/backward parsing so it cannot loop
then this commit should be reverted

Fixes an assert in file from trac ticket 3188.

Fixes crash/valgrind errors in trac ticket 3188 and hang in 3274.

Runtime of the full 32x32 idct goes from 2446 to 2441 cycles (intra) or
from 1425 to 1306 cycles (inter). Overall runtime is not significantly
affected.

Runtime of all IDCTs together goes from 3327 to 2473 cycles (intra, i.e.
~35% faster) or from 2312 to 1448 cycles (inter, i.e. ~60% faster). Total
decode time of ped1080p.webm goes from 8.086sec to 7.974sec (1.4% faster).

Sub-IDCTs will follow later. ped1080.webm goes from 9.295s to 8.191s
(13.5% faster). The IDCT itself goes from 4372 (intra) or 4337 (inter)
to 403 (intra) or 329 (inter) cycles for the DC-only form, 23755 (intra)
or 23723 (inter) to 3497 (intra) or 3607 (inter) cycles for the no-DC
form, which averages from 23393 (intra) or 16612 (inter) to 3449 (intra)
or 2392 (inter) for all 32x32s together, i.e. about ~7x faster (all
tests done on ped1080p.webm).

Fixes ticket #3261 visually.
