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!

Another performance improvement. A logarithmic operation in
SearchBorder<> has been turned into a small-constant operation plus a
much smaller logarithmic operation. This buys almost 15% in my tests.

Actual fix for y4mdenoise/SkipList.hh compile problem with gcc 4.0.1.

Possible fix for y4mdenoise/SkipList.hh compile problem with gcc 4.0.1.

Checked in y4mdenoise "version 3 beta 3".

A bunch of little bug fixes, and a couple of big performance
improvements, found while reading over the code.

Checked in y4mdenoise "version 3 beta 2".

These are all of the cleanups and performance improvements I can think
of. The next step is to rewrite the code to take maximum advantage of
symmetric multiprocessing. The only changes I plan to check in before
that will be fixes for any bugs found.

the memory is freed everywhere else before returning except here, the non-errpr
case.
