emulate getgrouplist() directly, no need to pull in
the wrapper from libc

pty.o in libutil.a wants to call getgrent_r(), so provide a cheesy
non-reentrant version here in order to avoid linker conflicts when
the rest of this file is attempted linked together with libc's
getgrent.o.

Reviewed by christos.

Include <unistd.h> to get the getgroupmembership() prototype.

Implement getgroupmembership(3). This is similar to getgrouplist(3), except
that the "int maxgroups" and "int *ngroups" parameters are separated into
two separate parameters which makes it possible to call multiple nsswitch
back-ends and have the results correctly merged.
getgrouplist(3) is now implemented using getgroupmembership(3).
