6ceb6c7f47 ntoskrnl.exe: Return zero for unknown msr registers. 
rdmsr should fault if called with the register not supported
by CPU. But until we want to support the full range of CPU
specific registers returning zero is probably a better
fallback.

a1c46c3806 server: Add USD support with timestamp updates. 
The USD page is created when the first process (wineboot.exe) completes
its creation, using its provided user_shared_data for initialization.

The server maps the page write-only and the clients map it read-only,
then the server updates the timestamps every 16 ms.

c988910cae ntoskrnl.exe: Update the tick count in KUSER_SHARED_DATA when accessed. 
EasyAntiCheat.sys constantly reads this value, so I think keeping it
up-to-date is a good idea.
