MJPEG Tools Svn

New upstream release.

remove mjpegtools-config, add mjpegtools-config.h.

remove redundant #ifdef HAVE_CONFIG_H block. The .cpp source modules already
do the #ifdef #include config.h _and_ exported headers should never use
HAVE_CONFIG_H or config.h

Fix APP/COM JPEG marker writeout

quoted #include "file" remaining. To be consistent those were changed to
#include <file>

Transistion period is over. Per discussion on the -devel list autogen.sh
becomes autoreconf -f -i

* change subfrequency carrier (patch by Douglas Fraser
<ds-fraser@...>)

Do something similar for the interlacing (print 't', 'b', p' instead of a numeric value).

Update the manpage to reflect the recent changes to mp2enc.
