Merge an endless story. The branch name is a lie, it was started as glsl, but now it is a complete reworked opengl3 backend.
It just began with simple changes which aren't supported on osx.
They either support ogl2 OR ogl3 core, but mixing isn't allowed.
As the branch name says, the vicious circle starts with GLSL, but just implementing one wasn't possible either:
- OSX supports only GLSL100 which doesn't support our shaders.
- Vertex Array Objects are needed for ogl3, but not supported on ogl2
- immediate mode isn't supported any more, so we must implement vertex buffers
- uniform buffers are recommended as else we would need tons glUniform
- postprocessing shaders have to be converted to glsl
- lots of smaller outdated issues and bug fixes :-)
Thanks at all for testing and at Sonic for converting all of our shaders to glsl130
And sorry for all upcoming bugs...

* FIFO-BP: (31 commits)
Set g_bSignalTokenInterrupt on the main thread. Fixes the random hang in Harry Potter: Prisoner of Azkaban.
Used a scheduled event to generate the ARAM DMA interrupt if the DMA is greater than a certain size. Fixes NFS:HP2 GC.
Bumped up the disc transfer speed enough to prevent audio stuttering in Gauntlet: Dark Legacy.
Enabled Synchronise GPU on "SPEED CHALLENGE - Jacques Villeneuve's Racing Vision". Required to go in-game.
Added direct GameCube controller commands to the Serial Interface emulation. Fixes the controls in MaxPlay Classic Games Volume 1 and the Action Replay disc.
Increased the FIFO buffer size to 2MB from 1MB. Fixes Killer 7's Angel boss.
Used an immediate GenerateDSPInterrupt when transferring data from ARAM to MRAM and a scheduled DSP interrupt when transferring data from MRAM to ARAM.
Fixes the audio cutting in and out in the Resident Evil GC games using DSP HLE. Triggered the ARAM interrupt by the scheduler instead of directly in function.
Implemented proper timing for the sample counter in the AudioInterface, removing the previous hack. Cleaned up some of the audio streaming code.
Skipped the EE check if there is a CP interrupt pending.
Disabled "Speed up disc transfer" from the ZTP GC game ini.
Removed the disc seek times for GC games and removed the disc speed option on Wii games. Checked for external exceptions only in mtmsr.
Delayed the interrupts in the EXI Channel.
Merge aram-dma-fixes (r76a13604ef49b522281af75675f044d59a74e871)
Added a patch that bypasses the FIFO reset code in Wallace and Gromit: Project Zoo, allowing it to go in-game.
Made vertex loading take constant time.
Increased the cycle time of the vertex command. Fixes "Speed Challenge: Jacques Villeneuve's Racing Vision".
Moved the setting of the Finish interrupt signal back to the main thread as it was causing Wii games like Resident Evil 4 (Wii) to hang.
Profile stores, fp stores and ps stores only to the fifo write addresses list. This should make the JIT a little faster as it will not be checking for external exceptions unnecessarily.
