Miscellaneous fixes from James Harvey's PalmOS porting work: - fixed numerous memory leaks (not Palm-specific) - corrected a couple of 32-bit-int assumptions (vital for Palm but generally a good thing anyway) - lifted a few function pointer types into explicit typedefs (neutral for me but convenient for the source-munging Perl scripts he uses to deal with Palm code segment rules) - lifted a few function-level static arrays into global static arrays (neutral for me but apparently works round a Palm tools bug) - a couple more presets in Rectangles (so that Palm, or any other slow platform which can't handle the larger sizes easily, can still have some variety available) - in Solo, arranged a means of sharing scratch space between calls to nsolve to prevent a lot of redundant malloc/frees (gives a 10% speed increase even on existing platforms) [originally from svn r5897]
