The timebases before where only guranteed to be 1/fps precisse
and could cause AV sync errors on low fps

otherwise a unexpected timebase could be choosen
that is one that is thousand times more precisse than requested
which can have sideeffects.

The new fields are only printed when they differ from their defaults

ARM: use numeric ID for Tag_ABI_align_preserved
segment: Pass the interrupt callback on to the chained AVFormatContext, too
ARM: bswap: drop armcc version of av_bswap16()
ARM: set Tag_ABI_align_preserved in all asm files

The fate checksum change is due to the header size having been wrong.

This might not be needed at the moment, but it's good practice to
pass it to all chained AVFormatContexts, if it would happen to be
used there at a later point.

All our ARM asm preserves alignment so setting this attribute
in a common location is simpler. This removes numerous warnings
when linking with armcc.

LDR with register offset and PC as base register is not available in
the Thumb instruction set so the addition must be done separately.

Option for Voice Activity Detection is added to speex encoder.
Speex detects non-speech periods and encodes them with just enough bits
to reproduce the background noise, aka ``comfort noise generation''.

While a 25 fps stream can in general store frame durations in 1/25
units, this is not true for the timestamps. For example a 25fps
and a 25000/1001 fps stream when they are stored together might have
a matching 0 timestamp point but when for example a chapter from
this is cut the new start is no longer aligned. The issue gets
MUCH worse when the streams are lower fps, like 1 or 2 fps.
This commit thus makes the muxer choose a multiple of the
framerate as timebase that is at least about 20 micro seconds precise

With this, when we use a finer timebase than neccessary to store
durations the demuxer still knows what the original timebase was.
