MJPEG Tools Svn

Patch from Nicolas Boos to check for JPEG headers if libjpegmmx wasn't found - otherwise might result in compile failures if the appropriate -dev packages/files haven't been installed

Updated docs to include new 'work-around' flag mechansim for iffy hacks needed
for particular applications.

Merged in fixes for DTS and LPCM and a special LPCM work-around for
mplayer. This work-around *could* be actually needed for hardware players... need
to check.

Ooops missing ctype include breaks many compile environments

remove -m from the option summary. obsolete since mplex autodetects if the
stream is MPEG-1 or MPEG-2

Attempt to solve the buffer alignment issue once and for all.
If posix_memalign fails try memalign (a compat function is provided) with
page alignment (some memalign implementations error out with anything except
page alignment). If all of that fails there's nothing left to do but log
the failure and bail.

Some modest tidying up leading to more code-sharing for the audio
streams and support for subtitle muxing from popular ripping formats.

some final changes for the next release.

Forgot a .PP command. Make the spelling of quantize consistent - some places
had quantise while others had quantize. Use quantize everywhere.

Add -X to the manpage.
