New opengl thread context selection patches for testing

[Stefan Dösinger]

Hi,
Here is a new patchset for testing which implements duplicating gl contexts 
for new threads in wined3d. Again, it does not implement any synchronisation 
measures(except ENTER_GL and glFinish), so running multithreaded games is 
still kinda a lottery.

This patchset also contains a patch for offscreen rendering, which may fix the 
problems introduced with TES: Oblivion before.

This is just a format-patch of my git tree, the first 3 patches are unrelated. 
One of them is a clone of Henri's already sent patch, and the other 2 patches 
were sent by me already.

Happy testing,
Stefan

Ok, i tried it with current CVS.

+ There are many improvments in some games like Tomb Raider Legends, GTA 
San Andreas, HalfLife Episode One and 3DMark 2005 or 2006
+ Oblivion is still broken (same as with previous patchset)
+ With your previous Thread patchset Rainbow Six Vegas can even run into 
menu, but now it hang while loading menu.
+ I can't find any other regressions :)

Tested with:
- 3DMark 2003
- 3DMark 2005
- 3DMark 2006
- Alpine Sky Racing 2007
- Battlefield 2142 Demo
- Call of Duty 2
- Flatout 2
- GTA San Andreas
- Half-Life 2 EO
- NFS: MW
- NFS: Carbon (can't run it before and after)
- All NVidia SDK Direct3D Demos
- Neverwinter Nights 2 (can't run it before and after)
- Polda 5 (czech game)
- Rayman 3
- Rayman Raving Rabbids (can't run it before and after)
- Rainbow Six: Vegas
- TES IV: Oblivion
- Titan Quest (still hangs in menu)
- Tomb Raider: Legend

With fbo game crashed after loading game.

Without patch 10 I can run Rainbow Six Vegas, even the game, but it is 
realy slow and graphic is very ugly.

Awesome job! Now several more games that didn't work start working:
- Indiana Jones and emperor tomb
- Prince of Persia Sands of the Time
- Psychonauts

All of them were crashing after playing intro video(s). The only finicky
game is Psychonauts. I had to force multi-threaded d3d and even then it
some times crashes. Apparently it's the case of thread safety that we
don't have yet.

In general it seems the good step forward allowing lots more games to
work on Wine.
