[rfc] realtime priority patch based on rtkit

[Maarten Lankhorst]

Hi all,

I decided to dig through the sample documentation for rtkit and see if I 
could find a way to make it work for wine.
There's still a few things missing: hardcoded libdbus soname, no 
checking if dbus is available, -I/usr/include/dbus-1.0 
-I/usr/lib/dbus-1.0/include should be added to ntdll/Makefile and 
SIGXCPU should demote all threads of the application back to normal priority

The server queues an APC to the target thread that signals it should try 
to acquire rt prio for it. the thread makes a request to rtkit over dbus 
to say it wants realtime. This is because rtkit requires the affected 
process to call dbus.

Any moral objections to this approach?

Cheers,
Maarten
