The server-side CsrSrvIdentifyAlertableThread and CsrSrvSetPriorityClass
functions are completely removed in Win2k3+, and are since stubbed by
CsrSrvUnusedFunction instead. They however were present up to Windows XP,
albeit with an extremely minimal implementation.
The corresponding client-side CsrIdentifyAlertableThread and CsrSetPriorityClass
now become just stubs that either trivially succeed or fail, respectively.

for more information.
- Fix typo "al*T*ertable" --> "alertable".
- Remove ROS-specific CSRSS_IDENTIFY_ALERTABLE_THREAD that was
deprecated since ages (at least before 2005)!
