Normally we discard things prior to the intended start
for stream copy this is not always possible, and its not done by default
this option allows discarding to be enabled

this is primarely usefull when transcoding a video and stream copying an
audio stream.

Without that change, all subtitles will stay until the next one.

Otherwise, all streams are finished and the time is nonsensical.

Eliminating finished streams avoids the progress stopping
with the first stream.
Using the max instead of the min avoids the progress stopping
with gaps in sparse streams (subtitles).
Negligible change for normal circumstances.

The code failed with negative timestamps due to using unsigned numbers

It will avoid a forward declaration.

It reduces the lifespan of buffers in filter graphs,
and therefore the memory consumption.

Rework the transcode() function and its immediate annexes to have
the same structure as in avconv, while still maintaining proper
scheduling to avoid accumulation.

Using -filter_complex without inputs now works.

The sub-movtextenc ref file changes because the dimensions
(400×60) are stored by the format.

With this option, transcoding DVB subtitles becomes possible.

Fixes Ticket1627

The fate change is due to ffmpeg no longer pushing audio timestamps
aggressively up (which is what caused the AV sync issues in the ticket)
but leaving them as they are.

The old code generates a termination packet with the same regions as the
start packet and page_state set to "only what changed"; the result is
that the termination packet is decoded as identical to the start packet.

The new code does as found in some DVB broadcasts: produce a packet with
no regions. This is done by expecting num_rects to be 0 rather than
using a flip-flop. ffmpeg.c is updated accordingly.

We're now running some of this code through valgrind for the first
time, and a few warnings showed up stemming from two problems.

1) The ASS code assumes the subtitle header is null terminated, but
it wasn't, and passing the size down doesn't look like fun, so I
added a terminator

2) The code wasn't freeing all of its state.

With this feature, it becomes possible to perform commonly
requested tasks, such as hardcoding bitmap subtitles.

This will be reverted once libavfilter has proper support
for subtitles. All the changes have the string "sub2video"
in them, it makes it easy to spot the parts.
