Encoding delay is adjusted for on-the-fly during encoding.
Decoding delay is compensated for by setting an appropriate dwStart on
the audio stream (only in muxer_avi at this point).

1. Include audio_delay as an argument to demux_seek.
2. Modify demux_seek_avi to adjust the audio/video stream positions so
that mplayer/mencoder will instantly be in sync even when -delay is
specified.
I've quadruple checked this time; hopefully I haven't missed anything.

patch replaces '()' for the correct '(void)' in function
declarations/prototypes which have no parameters. The '()' syntax tell
thats there is a variable list of arguments, so that the compiler cannot
check this. The extra CFLAG '-Wstrict-declarations' shows those cases.
Comments about a similar patch applied to ffmpeg:
That in C++ these mean the same, but in ANSI C the semantics are
different; function() is an (obsolete) K&R C style forward declaration,
it basically means that the function can have any number and any types
of parameters, effectively completely preventing the compiler from doing
any sort of type checking. -- Erik Slagter
Defining functions with unspecified arguments is allowed but bad.
With arguments unspecified the compiler can't report an error/warning
if the function is called with incorrect arguments. -- Måns Rullgård

Other demuxers could be modified similarly in the future.

this may go against the original intention of the vf layer, but it's
how all the filters that drop frames have been written to work, so
it's now the de-facto standard.
without this patch, -noskip will result in tons of duplicate frames
(either soft or hard duplicates) and a/v desync whenever decimation,
ivtc, etc. is used. even with this patch -noskip is still a bad idea
for most of these purposes, but it will work reliably with filmdint,
framestep, and some other filters with fixed in:out ratios as long as
the right -ofps value is used. without this patch, there is no hope of
-noskip working with frame-dropping filters.
(this patch was previously committed erroneously as part of another
change, then reversed. it is now being committed again.)

whoever made rawvideo muxer disable audio!!
with this patch, audio is processed but simply thrown away by the
muxer. various 'error' conditions in rawvideo muxer are removed to
make it work. feel free to re-add them if they can be done without
breaking anything, but do not use printf !!!!
btw old behavior can be obtained by manually specifying -nosound.

mencoder a.avi b.avi -flag c.avi
-flag should've only applied to b, but it applied to both b and c!!
No clue why this happens and more so why this solves it. but it does.

fixdelay() pre-read a frame to make pts sane, and then called slowseek(),
which AGAIN read another frame, and then tries to decode it (which breaks
as all frames should be read)

video is unreliable with -ovc copy.
