Right now those muxers use the default timebase in all cases(1/90000).

This patch avoid unnecessary rescaling and makes the printed timestamps
more readable.

Also, extend the printed information to include the timebases and packet
pts/duration and align the columns.

Obviously changes the results of all fate tests which use those two
muxers.

av_realloc() does not guarantee alignment, which is required for
DSPContext.bswap_buf().

This will be useful to test more aggressively for failures to mark XMM
registers as clobbered in Win64 builds, and prevent regressions thereof.

Normally, the actual payload data contains sequence headers, too,
and the parser can extract this and set it as extradata. However,
the data in the dvc1 atom is the "official" extradata for the file.

This is required for proper stream copy of vc1 from ismv to ismv.

Do not use AVStream's duration for dts generation since it contains in
some cases the duration of the whole file instead of duration of the
samples in the moov. This happens if the mdhd holds the duration of the
whole file but has no entries or a zero duration in its stts.

There is no point in this test using the RM format.

Return the correct number of consumed bytes and set *data_size = 0.
Returned size is 1 too small, leading to that 1 byte being read as the next
frame, which results in an extra blank frame at the beginning of the stream.

Avoids doing malloc/free for each frame.
Also fixes valgrind errors due to use of uninitialized padding bytes.

Specifies the correct number of xmm registers used so that they can be saved
and restored on Win64 if necessary.

It is already the correct size as set by ff_alloc_packet().

This will simplify encoders which use this function to request the exact
packet size rather than the maximum size.
