RFC: NSS prototypes

[Andreas Jaeger]

Compiling glibc we now get lots of warnings like:

$ grep warning make--out |grep setprotoent
nss_files/files-XXX.c:116: warning: no previous prototype for `_nss_files_setprotoent'
nss_hesiod/hesiod-proto.c:50: warning: no previous prototype for `_nss_hesiod_setprotoent'
nss_nis/nis-proto.c:110: warning: no previous prototype for `_nss_nis_setprotoent'
nss_nisplus/nisplus-proto.c:162: warning: no previous prototype for `_nss_nisplus_setprotoent'

I'd like to fix all these NSS related warnings with a patch like the
following.  What do you think?  Shall I finish the patch?  Or what
needs changing?
