Source changes:
---------------
- Added check and failure for 0-sized mallocs  [Nathan Woods].
- Added MMU support to the MIPS3 dynamic recompiler. Re-enabled it by default. Added direct fast RAM access to the dynamic recompiler, as well as optional hotspot optimizations. Most games should show a net speedup over the pre-MMU compiler [Aaron Giles].
- Added preliminary save state support to 'Missile Command' and 'Battlezone' [Buddabing].
- Added rudimentary hotspot detection to the debugger. Type "help hotspot" for details on how it works [Aaron Giles].
- Added sprites banking, tile banking, sound banking, and a couple of DIP switches to 'Egg Hunt' [Pierpaolo Prazzoli].
- Changed the way encrypted CPU memory is allocated and managed. Previously, memory_set_opcode_base() was used to set a single pointer to the decryptedopcodes; however this presented a number of limitations. Now that all RAM and ROM-like regions are assigned banks, the memory system now tracks decrypted opcodes per bank. For implicit banks (marked RAM or ROM in the memory map), a new function memory_set_decrypted_region() configures which areas of the address space contain decrypted opcodes and where the decrypted opcodes live. For explicit banks, there is a new function memory_configure_bank_decrypted() which operates identically to memory_configure_bank() but specifies a pointer to the decrypted opcodes on a per-bank basis. Updated all drivers using the old mechanism to the new mechanism and removed the old system [Aaron Giles].
- Cleaned up the way the debugger hooks into the memory subsystem. Now, on each CPU switch, the debugger queries the memory system for callbacks to be called on every read/write. This allows more efficient watchpoint tracking and allows for non-watchpoint debugging behaviors like the hotspot detection [Aaron Giles].
- Fixed a number of games that were broken with the u1 update. Just a few more cases remain. Most games are working at this point [Aaron Giles, with contributions from El Condor, R. Belmont, Ville Linde] 
- Fixed activecpu_dasm() and cpunum_dasm() to detect the presence of an updated disassembler and wraps the calls to that rather than crashing [Aaron Giles].
- Fixed DTD in the -listxml output [Oliver Stoneberg].
- Fixed FPU decoding and a few other minor issues in the i386 disassembler [Aaron Giles].
- Fixed inputs in Woodpecker [Pierpaolo Prazzoli].
- Fixed MESS UI code that prevented P and Esc from being intercepted properly [Lawrence Gold].
- Fixed some dips in 'Pop's' Pop's [Sonikos].
- Merged in recent updates from MESS PC emulation code [Nathan Woods].
- Reduced how often the debugger display is refreshed if stepping and steps_until_stop is a high number.  This makes commands like 'step #10000' a bit more usable [Nathan Woods].
- Thanks to the new opcode handling, removed "RAMROM" support from the memory subsystem altogether, and updated all drivers to simply limit their decryption to areas that the CPU decrypted [Aaron Giles].
- Updated 6502 family of disassemblers to the new disassembler style. Added internal memory maps for the m6510 and m4510 CPU cores. Updated m4510 to use address translation hooks [Nathan Woods].
- Updated i86 and i286 cores to hook into the new i386 disassembler [Nathan Woods].
- Updated PowerPC core to use new disassembler style [Nathan Woods].
