MJPEG Tools Svn

Remove unused/not-needed _progname comment line.

Some versions of gcc added 'core2' in addition to 'nocona'. Apple's gcc 4.x
does not accept that option so workaround the new flag by doing a test compile

Intel Core2 detection from Gert Vervoort

A bug was postet to the mjpegtools tracker:
https://sourceforge.net/tracker/?func=detail&atid=105776&aid=2834856&group_id=5776

about: pipelist.c: missing fclose()

it was postet original here:
https://bugzilla.novell.com/show_bug.cgi?id=527725

amazing how each release of g++ manages to break code that's compiled for years.
seems g++ 4.4 had an issue with strrchr() at line 56

Overrun somewhere - from a contributor on the mailing list is the overkill fix
of allocating lots more than is probably needed

Fixed an integration error.

This commit was manufactured by cvs2svn to create tag 'y4mdenoise_v3_beta5'.

Rewrote y4mdenoise's BitmapRegion2D<>::FloodFill() to do less region
math, in favor of direct pixel-oriented operations (which is more
natural for bitmap regions). Now the zero-motion and match-throttle
flood-fills use bitmap regions, but the pruning flood-fill still uses
set regions, because it's faster that way.

This leads to a 35%-45% performance increase in my tests!
