Update.
* nscd/connections.c: Implement r/o sharing of nscd's cache with client
processes via shared memory.
* nscd/nscd-client.h: Likewise.
* nscd/nscd.h: Likewise.
* nscd/nscd_conf.c: Likewise.
* nscd/nscd_getgr_r.c: Likewise.
* nscd/nscd_getpw_r.c: Likewise.
* nscd/nscd_gethst_r.c: Likewise.
* nscd/nscd.conf: Add new config parameters.

* nscd/nscd_helper.c: New file.
* nscd/mem.c (gc): Indicate beginning and end of the gc cycle.
* nscd/hstcache.c: Simplify a lot. We cache only the request itself,
no derived information.
* connections.c (nscd_init): Fix bug in testing size of the persistent.
* nis/Makefile (aux): Add nis_hash.
* nis/nis_hash.c: New file. Split out from nis_util.c.

* csu/tst-atomic.c: Improve atomic_increment_val test which would
not have found a ppc bug.
