This heuristic is less likely to overshoot and cause encoder failure.

dr1 seems to work fine with frame size changes but many filters
cant handle it yet. Simply disabling it forces the alternative
non dr1 code path which has been tested more completely and
is known to handle frame size changes in a wider varity of
cases.

Allows working around issue #605.
Note: as a side effect this fixes that -vsync drop
as far as I could tell would not drop pts/dts values
when duplicating frames or when flushing encoder delay.

With this we can always know if a timestamp is based on added durations
from an unknown origin or if it is based on a correct timestamp (and possibly
added durations)
This should fix some bugs where this distinction was mixed up.

commit 13f6917ca9 handles discards automatically,
but the ffm discard options are not fully parsed. Causing the input streams not
to be used, so no stream towards the ffserver after the initial probing.

This is somewhat redundant as no decoder should call get_buffer() with such argument.

Mostly useful for debugging purposes.

If there ost->picref is NULL, it will likely crash anyway a few lines
below by dereferencing it in order to access video attribute.

filtered_frame is overwritten just below anyway.

This make do_video_out() and do_audio_out() consistent. Also simplifies
callers.

This simplifies a bit the #ifdefery.

This avoid a forward declaration.

This will allow some simplifications in transcode_video().

input_video_filter and output_video_filter can't be NULL at this point.
If they are, the current code would likely crash anyway (since
filtered_frame would be NULL and sent to do_video_out().

The added tests are limited to the case where timestamp discontinuities
are not allowed. The default is 30 hours which is arbitrarily picked and
quite conservative.
This prevents a out of memory condition due to duplicating a frame
millions of times.

It currently has different meanings at different times (dts of the last
read packet/pts of the last decoded frame). Reduce obfuscation by
storing pts of the decoded frame in the frame itself.
