dlls/x11drv. Removed a number of unnecessary #includes.

and error_status_t types. Improved some parsing rules to get rid of
the LINK_LAST and LINK_SAFE macros. Enclose generated .h file within
an extern "C" (for C++). Output function prototypes for regular RPC
interfaces.  Fixed a couple of bugs.

Call INT_Int21Handler only to emulate selected functions.

- implement GetCaps for D3DDevice7

- preliminary implementation of endpoint-mapping via a new on-demand
  server-ish process
- more header fixups
- (re)implement RpcEpRegisterA, RpcEpUnregister, and
  RpcEpResolveBinding using the new rpcss functionality
- update the todo list in rpcrt4_main.c a bit
- many beautifications and touch-ups
- command-line configurable timeout
- micro-client imbedded in np_server.c

failing.

- prepare for multi-texturing support

directly winedos int21 handler.

- 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.
