randr: set error numbers of resource types in RRExtenstionInit() (V2)

Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=30367

Currently the ddx calls xf86RandR12Init()
  (-> RRScreenInit()
     -> RRInit()
       -> RRModeInit()
       -> RRCrtcInit()
       -> RROutputInit())
before RRExtensionInit() is called. This causes RRErrorBase
being 0 while setting resource type error values (resource types:
RROutput, RRMode and RRCrtc). The fix moves the setting of error
values to own functions which are called in RRExtensionInit()
to get the right RRErrorBase.

V2: With header file
