getopt-gnu: flush out another BSD bug
POSIX requires 'echo foo > bar; m4 -Dfoo=1 bar -Dfoo=2 bar' to

setenv, unsetenv: work around various bugs
POSIX requires setenv(NULL,"",0), setenv("a=b","",0),
unsetenv(NULL), and unsetenv("a=b") to fail with EINVAL, but
many BSD implementations lack validation. The gnulib
replacement for void unsetenv did not do validation, and the
replacement for setenv was out of sync with glibc. Also, some
BSD implementations of setenv("a","==",1) eat the leading '='.

getgroups: don't expose GETGROUPS_T to user
These days, most systems already declare getgroups with gid_t*.
But in the rare case that GETGROUPS_T is still int but gid_t
is short, the user should not have to uglify their code; let
the replacement hide all the magic.
Tested by configuring with ac_cv_type_getgroups=uint64_t on a
platform with 32-bit gid_t, and ignoring compiler warnings.
However, since we don't replace setgroups, the GETGROUPS_T
workaround is still needed there for now.
