kernel - Add uid, gid, and inum to stat data for pipes

* fstat(pipefd) now populations additional fields. uid, gid,
and inum. In-line with other BSDs and Linux. Not sure why
any program would use the inum field but... now its populated.

* Add an anonymous inode allocator to the pcpu structure. No
atomic ops required. Basically just does:

pipe->inum = gd->gd_anoninum++ * ncpus + gd->gd_cpuid + 2;

* Facility can be used for other things as needed.
