Log Message:
Overhaul the use of nsdispatch(3) by public APIs so that the back-end
methods use va_list in a manner that is directly related to the public API.
This makes it much easier to write dynamic nsswitch backends for getgrent(3).
Per my proposal on tech-userlevel.

Implement getgrgid_r() and getgrnam_r() APIs per the POSIX 1003.1, 2004 Ed.
These aren't fully reentrant or threadsafe yet, because the compat stuff
currently uses non-reentrant data sources (getnetgrent(3), getgrent(3)),
and there is probably some locking to be improved in the backends.
This will be fixed in the near future.
We also need to add _SC_GETGR_R_SIZE_MAX to sysconf(3).
