The muxer will write at least the number of bytes requested and possibly
up to 3 bytes more.  This is because the muxer writes 32-bit integers
and the format requires 4-byte alignment anyway.

AVI does not really support vfr properly, only by padding with null
packets.

When av_reallocp fails, the associated variables that keep track of
the number of elements in the array (and in some cases, the
separate number of allocated elements) need to be reset.

Not all of these might technically be needed, but it's better to
reset them if in doubt, to make sure variables don't end up
conflicting.

Since 596e5d4783, this is not necessary anymore. It also allows to
actually disable the flushing, improving write performance (but
possibly giving worse latency in real-time streaming).

It will be useful in the wav muxer.

This is consistent with stdio and is what we want to do in all cases.

Fixes a bug in the voc muxer which didn't flush in write_trailer()
previously. This is the cause of the change in the test results.

This removes the use of macro nesting in these code constructs, which
makes it easier to parse in pre-processors.
