This crash was discovered by Dalai and this happened because of
unset current context (as result of call wglMakeCurrent(NULL, NULL)).
In this case glGetString(GL_VENDOR) returns NULL. Rather than add check
for vendor != NULL before string comparison, I've changed a bit logic of
context creation:
- Create context and set it as current
- If it's crappy Intel card -- delete this context and
share the only one context between all Windows
- Otherwise, use initial logic (with sharing lists and so on)
This could also fix crash when opening userprefs from a menu with Intel card.
Intel video cards don't work fine with multiple contexts and
have to share the same context for all windows. This could work
incorrect with multiple video cards configuration, so suppose
there'll be no such situation (Intel cards are mostly in portable
devices like notebooks and laptops, where there's actually no
dual video cards). Anyway, it should work much better now.
Non-Intel cards behavior was kept unchanged.
Thanks to Ton for debug session :)

by Alexander Kuznetsov
The amount of mouse grabs wasn't properly balanced with ungrabs, thus preventing from using proper mouse input outside client area.

A whole new way of handling keyboard input improves greatly both code readability and event handling. Thanks for the great patch, Alexander!
Fixed view selected code. Made MDisps->disps use the
special allocation library I wrote as a
temporary fix to MDeformGroup->dw problems.
Why was the vgroup solution reused? It's really slow,
and its hard to tie in something like mempool or memarena.
The hackish allocator I wrote really needs to go, eventually,
or be folded into guardedalloc.
Also fixed a customdata bug with modifiers.
Mirror modifier no longer uses bmesh, but is now
100% CDDM. This is faster; the sluggishness was
driving me crazy. Still need to deal with UVs,
but that shouldn't be hard.
