Florian Weimer 039ff51ac7 nscd: Do not rebuild getaddrinfo (bug 30709)
The nscd daemon caches hosts data from NSS modules verbatim, without
filtering protocol families or sorting them (otherwise separate caches
would be needed for certain ai_flags combinations).  The cache
implementation is complete separate from the getaddrinfo code.  This
means that rebuilding getaddrinfo is not needed.  The only function
actually used is __bump_nl_timestamp from check_pf.c, and this change
moves it into nscd/connections.c.

Tested on x86_64-linux-gnu with -fexceptions, built with
build-many-glibcs.py.  I also backported this patch into a distribution
that still supports nscd and verified manually that caching still works.
