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/Makefile (aux): Add nscd_helper. * 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. * nis/nis_util.c: Move __nis_hash code in separate file. * csu/tst-atomic.c: Improve atomic_increment_val test which would not have found a ppc bug.
