- Remove the now unneeded CSR messaging support. - CsrInit() goes away also and the usage of the CsrProcess is replaced by that of gpepCSRSS. [WINSRV] - Use a DLL instance for loading resources, instead of calling GetModuleHandle. [KERNEL32/NTDLL] - Remove unneeded variables. svn path=/branches/ros-csrss/; revision=57665
