- implement Lock function to prevent crash when the stubs are used

flag.

 - implementation of D3DFVF_TLVERTEX format fast path

 - some other miscellaneous fixes

   glDrawPixels interface (slow but should be enough for a start)
 - implement one vertex case for the D3D3/7 DrawPrimitive functions
 - fix a missing \n in a TRACE call

- Added support for running all the tests in batch.

on Win95 -> use GetProcAddress.
Cleanup the handling of OpenThread.
Check SuspendThread after a thread terminates (needed by Ipix).
Remove unnecessary version checks (check for
ERROR_CALL_NOT_IMPLEMENTED and similar instead).
Cleanup casts, signed/unsigned comparisons.

GetDiskFreeSpace("." | "..") fails on Win98 and NT4 but succeeds on XP
-> removed.
Skip the GetDiskFreeSpace tests on floppy drives because NT pops up a
MessageBox if no floppy is present.
Fix the error code checks to take into account the differences between
Win9x, NT4 and XP.
Skip the unicode tests if the first call returns
ERROR_CALL_NOT_IMPLEMENTED.
Whenever a test fails, print sufficient information (typically return
code and GetLastError()!) to let the developer figure out what is
wrong.

SetEnvironmentVariableA("", value) crashes on NT4 -> removed.
The behavior of SetEnvironmentVariableA("", "") varies to much ->
removed.
Test the behavior of SetEnvironmentVariable{A,W}(name, "") taking into
account the differences between Win9x and NT.
Test the behavior of GetEnvironmentVariable{A,W}(name, buf, 0).
Fix the error code checks to take into account the differences between
Win9x, NT4 and XP.
Skip the unicode tests if the first call returns
ERROR_CALL_NOT_IMPLEMENTED.
Whenever a test fails, print sufficient information (typically return
code and GetLastError()!) to let the developer figure out what is
wrong.

methods declaration.

names "DUMMYUNIONNAME" and "DUMMYSTRUCTNAME" for anonymous unions and
structs. Support const and extern definitions. Retain tokens (and
whether numbers are hex or not) used for computing constant
expressions, so that the full expression can be written to the header
file instead of the computed integer result of the expression. Parse
the sizeof() operator.  Compute and remember constant definitions and
enum values so they can be used in expressions. Improved identifier
lookup speed. Fixed some bugs.

- optimize a little bit the DrawPrimitive function

 - add texture memory usage tracking

that we don't import stubs directly.
