Fixes a segfault in exit_program() if opening an output file fails.

Document the functions and have both use a millisecond timeout and
check for interrupt.

Previously it was grown one element at a time, which leads to
excessive reallocations.

The previous allocation increment of 16384 meant that the cluster
array was allocated for 0.6 MB initially, which is a bit excessive
for cases with fragmentation where only a fraction of that ever
actually is used.

Therefore, start off at a much smaller value, and increase by
doubling (to avoid reallocating too often when writing long
non-fragmented mp4 files).

When writing fragmented mp4, the cluster array is reset when a
fragment is written. Instead of starting off reallocating the
array only based on the number of current elements in it, keep
track of how many elements there were allocated earlier.

This avoids reallocating this array needlessly when writing
fragmented mp4 files.

The buffer is used for an additional pass of frame compression, so videos
can be coded without ever using it (and some are coded so indeed, e.g. in
Woodruff and the Schnibble of Azimuth game).

Introduce ff_listen_connect, to be shared with the other

Introduce ff_listen_bind, to be shared with the other non-tcp

Indeo 4 has quantiser range 0-31 instead of 0-23 for Indeo 5, and clipping
quantiser leads to incorrect quantisation and DC prediction on low-quality
videos.

This fixes bug 259.
