the intent is to replace the haphazard scheduling and finger-crossing associated with saving/loading with the correct and minimal necessary wait for each thread to reach a known safe location before commencing the savestate operation, and for any already-paused components to not need to be resumed to do so.
* misc-speedups:
fixed and reenabled and slightly optimized the JIT version of fcmpo/fcmpu.
slightly more precise speed percent display (this is really minor)
a small thread synchronization speedup for dual core mode. it's most noticeable in games where the CPU is running behind compared to the GPU.

The Fifo.cpp changes from rdaefb3b550e2 was not merged as there was no performance benefit.
This branch reduces the number of useless state flushes in the video
emulation layer by checking whether a BP/XF change will have an effect
or not. Greatly reduces the number of GL calls per frame.
Thanks to degasus for his help!
When a game writes the same value that was already configured to a BP
register, Dolphin previously flushed the GPU pipeline and reconfigured
the internal video state (calling SetScissor/SetLineWidth/SetDepthMode).
Some of these useless writes still need to perform actions, for example
writes to the EFB copy trigger or the texture preload registers (which
need to reload the texture from memory).
This allows users to easily check whether their Wii dump is corrupted or not
using the Dolphin properties window. Right click on a game, Properties,
Filesystem tab, then right click on the game partition and select "Check
partition integrity".
This may have some false negatives due to the unused clusters heuristic (see
the comment in VolumeWiiCrypted.cpp). False positives are unlikely.
* JIT-Exceptions:
JitIL code cleanup
Changed the JIT code to make the FPU exception timing more accurate. The exception is now triggered at the first FP instruction instead of the start of the block. Rearranged the JIT exception code for a tiny speed-up. Only external exceptions are checked at the end of the block. All other exceptions are checked at the time they occur.
Fixes issue 5382.
Conflicts:

* AudioStreaming:
Reset the stream playing flag on init.
force VolumeDirectory to align files to 32KB (only streaming audio files really need to be aligned...)
Removed the DTK Music option. It is now always enabled.
Added the response for audio streaming disc offset requests. Generate an AI interrupt at the end of the audio streaming loop. Fixes Pac-man Fever and the background music in Eternal Darkness.
Fixed the erroneous looping in audio streaming games like Eternal Darkness and Zoids: Battle Legends. Thanks for the tip, tueidj.

some how I neglected to remember that r+ requires the file to exist.
still should fix the issue with 0 byte memory cards.
This reverts commit 6bfb8c9597.
This adds an "Analyzer" tab to the fifoplayer dialog which allows to conveniently browse through all register pokes that are being sent by the game each frame.
There's also a search function, but it doesn't work all that well for anything but simple searches at the moment. However, I'm merging this anyway since I'm not sure if I'm going to finish this.
Note that due to recent fifo changes, it's not yet possible to run fifoplayer in dual-core mode.
please test for regressions, speed and for other issues fixed, as a example, the black color in water splash in super mario galaxy are fixed with this rev.
please as soon as yo find a bug let me know.
a little code cleaning to avoid duplicated execution of AlphaPreTest and a little correction to some comments from the previous commits.
this change must behave exactly like last revision, if something is broken please let me know
The decided way to find Wii Remotes is by their bluetooth name, so
this patch introduces common code to identify if a given string is a
valid Wiimote name.
On Mac, when scanning bluetooth, consult the function with all found
bluetooth devices.
There are two ways to send commands to Wii Remotes:
- On command channel, with a first byte of 0x52. This works on
Nintendo RVL-CNT-01, but not Nintendo RVL-CNT-01-TR wiimotes.
- On interrupt channel, with a first byte of 0xa2. This works on
Nintendo RVL-CNT-01 and Nintendo RVL-CNT-01-TR wiimotes.
This patch switches Mac from the former to the latter. Windows and
Linux remain unchanged.
This reverts commit c9dfcf8cf7.
That commit attempted to support all Wii Remotes on Mac OS X, but the
logic was incorrect, and as a result the original (non-TR) Wii Remotes
were broken by that change.
Future patches will address this problem in a better way.
/fp:fast was introducing FP precision problems, and mixing it with some
/fp:precise code caused strange game behaviors, DSI exceptions and freezes.
This commit should fix most of the issues introduced by 3.0-73 (r95517a97).
Thanks to hatarumoroboshi@hotmail.com for tracking a lot of these Win32 bugs.
Fixes issue 4906.
Fixes issue 5138.
Probably fixes (not tested) issue 5067.
to marcosvitali.
Added an external exception check when the CPU writes to the FIFO. This allows
the CPU time to service FIFO overflows. Fixes random hangs caused by FIFO
overflows and desyncs like in "The Last Story" and "Battalion Wars 2". Thanks
to marcosvitali for the research.
Added some code to unlink invalidated blocks so that the recompiled block can be
linked (speed-up).
This release still fixed the hangs produced by fifo overflow without sacrifice
performance. For example you can test Tutorial moves at the beginning of The last history now
is fluid 30/60.
Fixed possibles random hangs in DC mode.
Fixed hangs in DC mode in (Simpsons, Monkey Island, Pokemon XD, etc)
Implemented accurate management of Pixel Engine Interrupts. Now the GPU loop
is stopped when a PE Interrupt needs to be managed and resumed when Pixel Engine
finish.
Fixed Metroid Prime 3 and 2 desync. And other games with desync because of
FIFO Reset. That happens because FIFO_RW_DISTANCE_HI must be written first, for checking
fifo.CPReadWriteDistance == 0, so some fifo resets was not managed in the right
way.
Fixed Super Monkey Ball in some cases when the game write the
WriteReadDistance need to be safe like the SafeCPRead.
Improved the CheckException for the GatherPipe writes in JIT, now only the
External Exceptions are processed.
Fixed definitely Pokemon XD in dual core mode. This game is doing something
not allowed. It attach to CPU the same fifo attached to the GPU in multibuffer
mode. I added a check to prevent overwrite the GPU FIFO with the CPU FIFO. If
the game do that on breakpoint the solution can fail.
Fixed ReadWriteDistance calc when CPRead > CPWrite.
Added Token and Finish cause to GP Jit checking.
Additional cleanup in CommandProcessor.

Don't use isascii() - just do it ourselves
Bump required wxw version (for shared libs)
There still seems to be linking issues on some linux distros, I can't reproduce it though...
