[SAVEVERSION+] VM struct changes.
- Serial/title is now linked to disc, instead of running ELF.
- Save states can be created during BIOS boot.
- Patches now apply based on the executing CRC, and only after the
entry point starts executing (fixes multi-game discs).
- Add "Fast Forward Boot" option.
- Split achievements download and activation, downloads occur on
initialization, but are not activated until after the ELF loads.
- Prevent HostFS access while in PS1 mode.
- Remove multiple sources of truth for ELF/CRC/etc.
- Move ELF state from global scope to VMManager.
- Prevent game fixes and hw fixes being active while booting game.
- Simplify game update.
- Flush recompilers after ELF loads. No point keeping boot code around
which gets overwritten.
Guest memory is now mapped into a shared memory/file mapping, for use
with fastmem.
64-bit and 128-bit arguments are passed by register/value instead of by
reference/address.
LDL/LDR/SDL/SDR now use 64-bit GPRs instead of SSE.
Allocate memory in an x86-64-compatible way
Another part of #3451
Note: While this shouldn't change how anything works, it's been the #1 source of breakage of 32-bit builds in #3451 (it was the cause for the failure of win32 to allocate memory and the failure of linux-32 afterward) so we should definitely make sure it gets tested
see #3523 for more information
While c782b62 added much more reliable game game startup detection, the
settings system did not yet gain that knowledge, but typically that's OK.
Typically the settings (and patches) are loaded according to the current
CRC, which happens once on bios boot (with general settings) and then again
when the game starts, which includes game-specific fixes, patches, etc.
However, if the setting are changed (and therefore also applied) after
the game CRC is known but before the game starts, such as if the user
presses Tab to change framelimiter while at the bios, then until now it
was accidentally applying the game's settings while still at the bios.
This commit makes the settings routine know whether or not the game actually
started, and apply the generic/game settings accordingly.
The goal is to reduce the burden for new architecture port.
Patch is mostly inspired from 3kinox initial patch. The diff are
*/ used ifdef instead of raw removal
*/ gui don't rely on UseMicroVU* option
*/ completely remove sVU_micro.* file
Performance note, it might be faster to replace the MODULO with an AND. Not sure on the impact
for the new time stretcher algo.
GSdx: fixed use-after-free (linux)
PCSX2:
* add a define to support address sanitizer (both rely on 0x20000000-0x3fffffff memory ranges..)
* sio_buffer out of bond (-1). Maybe we can move the flush in the 2 if previous branch. It would
avoid the extra test.
* wxGetEnv (linux) generates double free (maybe not thread safe). Cache the result so it doesn't crash
anymore when switching renderer
Comment/Review/Improvement are welcome :)

Threading VU1 took a lot of rewrites and new code to make possible (MTGS, microVU, gifUnit...), but we finally got to the point where it was feasible, and now we've done it! (so now everyone can stop complaining that pcsx2 only takes advantages of 2 cores :p).
The speedups in the games that benefit from it are great if you have a cpu with 3+ cores (generally a 10~45% speedup), however games that are GS limited can be a slowdown (especially on dual core cpu's).
The option can be found in the speedhacks section as "MTVU (Multi-Threaded microVU1)". And when enabled it should should show the VU thread-time percentage on the title bar window (Like we currently do for EE/GS/UI threads).
It is listed as a speedhack because in order for threading VU1 to have been a speedup, we need to assume that games will not send gif packets containing Signal/Finish/Label commands from path 1 (vu1's xgkick). The good news is very-few games ever do this, so the compatibility of MTVU is very high (a game that does do this will likely hang).
Note: vs2010 builds and Linux builds need to be updated to include "MTVU.h" and "MTVU.cpp".

* Applied the new RecompiledCodeReserve to the VIF recompilers (saves another 4-8mb of memory, depending on game).
* Fixed a bug in pxsFmt / FastFormatUnicode (string formatting).
* Final round of error handling cleanups.
(branch is basically ready for re-integration -- needs some testin for obvious/show stopping bugs, thanks!)
git-svn-id: http://pcsx2.googlecode.com/svn/branches/newHostVM@4025 96395faa-99c1-11dd-bbfe-3dabce05a288
* Added some bounds checking to debug builds for VTLB mappings.
* Fixed a VU mapping bug that caused boot crashing
* Fixed some startup, shutdown, and reset resource management.

* SuperVU note: SuperVU recompiler now uses two separate 8mb caches for VU0 and VU1 (needed in order to simplify/saneify the reserve/alloc stages of pcsx2 app startup).
* Added MemsetFast.inl, which houses SSE intrinsic versions of memset and memzero, for use on aligned data targets.

* EE and IOP recompilers are using the new RecompiledCodeReserve class.
* PS2 main memory should typically be located at 0x20000000 (code still need some cleanups)
VU0/VU1 recompilers will be implemented soon.

* Convert IsoFileFormats.cpp into a class.
* Use wxFile and wxFileInputStream instead of windows/posix specific file functions.
* Added new ScopedAlloc classes, which are very simple dependency-free templates for exception-safe allocations.
* FastFormatString: Improved performance ad fixed an obscure bug.
* Drag&Drop (UI) - Improved the friendliness and responsiveness, so that PCSX2 doesn't end up tying up an explorer window while it prompts the user or issues error messages.

* Includes a minor tweak to DMAC.h - removed tDMA_TADR / tDMA_MADR / etc. and replaced them with a single tDMAC_ADDR class.

- Have the compiler explicitly pack the VU reg structs since we rely on this.
- Various minor changes.

I also re-implemented R5900 runtime exception handling for TLB Miss and such (devbuilds only, for now).

DevNote: Adding SysForwardDefs.h, which I'm going to use for forward declaring a bunch of PCSX2 classes and other simple dependency-free include content. This is the SysCore version of AppForwardDefs, and hopefully helps minimize header file hell.
