openbor Tools

Complete rewrite of Simple 2x scaling filter to remove more GPL-licensed code
from the engine. The implementation ended up being very similar, even though
I didn't look at the original code until after finishing my own
implementation.

Enable remap and blend for 8 bit transform (transform.c).
Minor debug message change(openbor.c).

Fix some debug messages.
Fix fill color and remap conflict under 8bit mode (3716).

Complete rewrite of the Scale2x (AdvanceMAME2x) filter. The old version was
based on an implementation licensed under the GPL, which is incompatible with
our license. Like the version it replaces, this rewrite has a fast MMX path
for x86 machines and a C path for everything else.

There's still a ton of GPL-encumbered code in the other scaling filters, but
this is at least a start.

Fix: shadowalpha 6 now works properly with corresponding map (inverted reflection, for example).
Minor: define savedata, savelevel and savescore in openbor.c instead of openbor.h; SDL port now uses pak name as window caption.

Incomplete change in entity defense property script access. Now fixed.

Fixed gif player on psp (removed platform specific and legacy code). Need more feedbacks.

Force memory clean up after reallocating a freespecial/cancel.

Replace all Dingux related code by OpenDingux

Fix a crash issue in 3710.
