The finding was that 99% of the time, textures are static in memory. However, Dolphin would pessimistically continue to decode and copy the same texture every time. The optimisation is to check if the texture matches what is in the cache, and if it does, Dolphin should early exit.
The result is the speed in New Super Mario Bros Wii increased 35% with spinning coins. Still not as fast as EFB copy to texture though.

Note that most users will want to use the release build to get a -O3 optimized build. This can be enabled by adding "-D CMAKE_BUILD_TYPE=Release".

I am officially killing the local/global build crap. The "local" build thing should never have existed. There is now only one build that is essentially what the "global" build was before. This is the way a proper build system should work. I will soon write a wiki page to describe how to properly use the cmake build system, and how you can still set things up to get the "local" build from before. However, that type of build should be considered a developer tool, and not the way that dolphin-emu should be built.
Briefly, to use cmake now do the following from the toplevel of dolphin's source:
mkdir Builddir
cd Builddir
cmake ..
make
make install (you may need superuser privileges)
Note that the scons build is still building dolphin in the old way.

Added autodetection of shared libraries.
Added a check for Xrandr.
Fix OpenAL linkage.
Copy User and Sys directories to lower case in the binary directory.

Also X11 is required on *nix systems.
GTK2 is required for building the wxWidgets builds on *nix systems.
Added a check for pulseaudio.

Explanation of this commit: We only have to care about four BP registers in ClearScreen, the remaining API state should be reset. The colorEnable and alphaEnable parameters are obsolete, for some reason directly using them caused the SMS glitch with DX11 (because of that bpmem.zcontrol.pixel_format == PIXELFMT_RGBA6_Z24 check in BPFunctions.cpp, is this one actually correct?)
The comment in BPFunctions.cpp was at least misleading (if not even wrong), so I removed it.
For what it's worth, someone needs to port this to the OpenGL and Software plugins (unless they're doing this properly already)

Some notes about this:
- config.h doesn't get written yet, so you'll have to use one generated by SCons
- dependency checking isn't really implemented, yet. Just some basic checks for OpenGL or ALSA, we need something more sophisticated though.
- the OpenGL plugin fails to load for some reason which I can't debug right now due to the libc debuginfo package version in openSUSE not matching the runtime packages
- there's even some support for generating install packages (rpm/deb/.. packages, NSIS installer, etc). It doesn't work properly right now though, since some paths seem to be hardcoded into Dolphin's source
- probably lots of other stuff I forgot... Just take a look at all the TODOs in the CMakeLists.txt files for more information ;P
Additionally, I added various files to the svn:ignore list.
tl;dr: Unless you are a dev or you're building binary packages, this commit shouldn't bother you :P

* Make writeToBackLog private to DSPIntExtOps.cpp
(JIT variants of 'l and 'ln are disabled and broken as is)
* Make zeroing of the backlog conditional on doing an interpreter fallback and
do it at a few more places
* Fix selection of cleanup for extended opcodes.
* Fix the DSP unit tests to correctly emit the function prolog/epilog
(else EBX wouldn't be saved)
* Add a few more DSP unit tests

Fixes issue 3399.
Also remove unnecessary stateman/gfxstate applies:
- gfxstate->ApplyState/Reset only need to be called by VertexManager
- stateman->Apply only needs to be called before any Draw/DrawIndexed call

Upon texture reloading, the cache entry hash wasn't updated and thus we effectively disabled any texture caching in that case.

Small performance improvements by increasing the ring buffer size and using a better offset algorithm.
