Reduce diff against avconv, and change some doxycomments into normal
comments (no point in doxifying ffmpeg internal fields).

Some of the FATE changes are due to off-by-one different rounding being used
(lrintf vs av_rescale_q).
Some fate changes are due to 1 audio frame less being encoded (the new variant seems
matching what qatar does and according to ffprobe its closer to the requested duration)
the mapchan feature sadly is lost in this commit because it depends on resampling
being done in ffmpeg.c which is now moved completely into the av filter layer
-async is broken after this commit, this will be fixed in subsequent commits
the new filter reconfiguration system is flawed and will drop a frame on each
parameter change which is why the nelly moser checksums need updating.

This fixes at least issues with empty lines, and also allows CRLF lines
(in case a user makes its own preset on a MS plateform).

Not all processing goes through filters,
so processing can continue even when
all filtergraphs have reached EOF on all sinks.

It allows ffmpeg filtering logic to work with filters
that do not implement the poll_frame method,
such as split or tile.

Audio timestamps are passed through by default and when the input
doesnt contain clean timestamps this can lead to non monotonicity
errors. (rounding to a course timebase can cause this too)

Print a warning when the errors in the timestamps are large

Fixes Ticket1167 (regression since timestamps are passed through)

This is a generic workaround that is intended to handle
slightly incorrect input files. It is very possible that some
demuxers contain bugs that lead to wrong timestamps, these demuxers
should of course still be fixed even if this change happens to
hide the issue.
