Changes to the main program:
----------------------------
- Support for 24-bit artwork [Mathis Rosenhauer].


Source changes:
---------------
- 6803/63701 external port writes no longer set to 1 the bits that are set as inputs in the DDR register. Instead, they are set to the value returned by a read from the port [Tatsuyuki Satoh].
- Change the API for tilemap_mark_tile_dirty() and the get_tile_info hooks, now a single parameter tile_index is used instead of (col,row). A function passed to tilemap_create() does the (col,row)->tile_index mapping, two standard functions are provided for the common cases. All drivers have been converted to the new API except for namcos2.c, which is therefore broken at the moment [Phil Stroffolino].
- New GAME_UNEMULATED_PROTECTION flag.
- Support for a priority buffer, updated by tilemap.c, which can be used to draw sprites using the new function pdrawgfx(). This allowed to fix many tile/sprite priority bugs e.g. in Ajax, Lightning Thunder, Simpsons, Vendetta, Punk Shot, Gradius III and others [Phil Stroffolino, Nicola Salmoria].
- Updated all memory handlers to the new READ_HANDLER()/WRITE_HANDLER() macro declarations. The old "function(int offset,int data)" style must not be used anymore.
