The getsysinfo(2), getrusage(2), and svrctl(2) calls used the same call number to different services. Since we want to give each service its own call number ranges, this is no longer tenable. This patch introduces per-service call numbers for these calls. Note that the remainder of the COMMON_ range is left intact, as these the remaining requests in it are processed by SEF and thus server- agnostic. The range should really be prefixed with SEF_ now.
