0001-Remove-support-for-GL_ARB_sync.patch

I strongly suspect that I'm having the same issue, which started since World of
Tanks released version 0.7.2. However, the shader error is a red herring. The
real problem is the deadlock:
err:ntdll:RtlpWaitForCriticalSection section 0x7bcb0ee4
"../../../dlls/ntdll/loader.c: loader_section" wait timed out in thread 0041,
blocked by 0009, retrying (60 sec)

I noticed that Debian's ancient 1.1.34 packages didn't freeze on login, so I
used git bisect and found that the problems start with commit
96b150929b0791c7c30ade49d55cedf2d608537e: wined3d: Add an ARB_sync
implementation of event queries. I manually reverted this in 1.5.1, tried
again, and got as far as logging into the game (previously impossible due to
deadlock), at which point I hit another deadlock that only happens after
committing to join a battle, which makes this highly undesirable to test on
one's real account:
err:ntdll:RtlpWaitForCriticalSection section 0x7bcb13e0 "virtual.c: csVirtual"
wait timed out in thread 0038, blocked by 0009, retrying (60 sec)
err:ntdll:RtlpWaitForCriticalSection section 0x110060 "heap.c: main process
heap section" wait timed out in thread 0009, blocked by 0038, retrying (60 sec)
err:ntdll:RtlpWaitForCriticalSection section 0x110060 "heap.c: main process
heap section" wait timed out in thread 0044, blocked by 0038, retrying (60 sec)
err:ntdll:RtlpWaitForCriticalSection section 0x110060 "heap.c: main process
heap section" wait timed out in thread 0036, blocked by 0038, retrying (60 sec)
err:ntdll:RtlpWaitForCriticalSection section 0x110060 "heap.c: main process
heap section" wait timed out in thread 0037, blocked by 0038, retrying (60 sec)
err:ntdll:RtlpWaitForCriticalSection section 0x110060 "heap.c: main process
heap section" wait timed out in thread 0045, blocked by 0038, retrying (60 sec)

I quickly removed GL_ARB_sync from the extension map altogether and tried
again, and found that it worked. I haven't had a chance to test this more than
once, but I had several failed attempts before I made this change, which
decreases the likelihood that it was a coincidence.

I'm attaching a patch that works around the issue by removing support for
GL_ARB_sync.
