Miscellaneous fixes from James Harvey's PalmOS porting work:

Browse Source 
- 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)
