_thiscall functions.
Fixed some bugs, and added a few missing functions.

  between cabextract.c and fdi.c
- reminders to eliminate global variables (for multithread
  compatibility)
- remove struct fdi_cab: due to the nature of the FDI API, we cannot
  preload all the cabinets; this appears to obviate the need for struct
  fdi_cab
- "oppress" (that is, do not process) partial files which were
  continuations from another cabinet
- more than one partial file can exist in a single cabinet (how!?) --
  so move the partial file notification (and "oppression" that goes with
  it) into the loop that iterates through files

retrieval of their interfaces via GetObjectInPath.
Fix and clean dsound and dmusics objects allocation when initializing
the performance object.
Some stubs improvements.

  faster on my NVIDIA hardware)
- small optimizations

  widechar classes.
- fix a stupid bug in callback handling caught by Lionel.
- add some forgotten IID on class factory (better if we want to active
  the code)
- many cleanups on COM Macros (don't need A and W variants as they are
  the same)

patch from Roderick Colenbrander.

- GetDC does not lock in ReadOnly mode as it leads to problems with
  some D3D optimizations
- added a fast Back => Front / Front => Back Blt fast path

- Make it more closely resemble the native control
- Add focus rectangle
- Misc fixes and cleanups

and Solaris as well.

- RtlDoesFileExists_U as a stub
- RtlDosSearchPath_U

- some more preparations for GL-accelerated Blts
- added debug code to compute FPS (nice when adding optimizations)

Add names to NetBIOS transports, and eliminates loopback adapters from
enumerated LAN adapters.

Reserve TEB field for DPMI virtual interrupt flag.

Some fixes based on patch by Ferenc Wagner.

Replace SHOULD_PEND macro with a function.

(spotted by Uwe Bonnes).

- some preparations for GL-accelerated Blts
- some small optimizations in the Clear code

- Fixed 4-bit RLE encoding of keyframes.
- Fixed signed/unsigned mismatches.
- Added some missing const's.

- "can" -> "do"
- a novella about a bug
- fix some memory leaks

get quad damage.
checkGLcall must not supply a \n as that is supplied by its
expansion.
Performance fixes to save applying the same states 6 times and to
reduce function calls when accessing front/back buffers.
Make traces more readable by more constants -> english descriptions.

  IDirectMusicPerformanceImpl (as the first inherits from the second)
- implement many Loader, AudioPath and Performance8 stubs - fix the
  class factory
- more debug traces
- for now IDirectMusicLoader8::LoadObjectFromFile always returns not
  supported format
- fix the IDirectMusicPerformance8::Init (many crashes)
- implementation of IDirectMusicPerformance8InitAudio

Fix small bug when keyboard buffer overflows.
Use DI_OK instead of 0 for returned values.
