setenv: relax requirement in light of POSIX ruling
Requiring that {un,}setenv gracefully reject NULL is just a waste
of processing power; POSIX agreed to this argument in
http://austingroupbugs.net/view.php?id=185
so we no longer worry whether a native implementation handles NULL.
* m4/setenv.m4 (gl_FUNC_SETENV_SEPARATE): Test handling of "" but
not NULL.
* tests/test-setenv.c (main): Relax test.
* tests/test-unsetenv.c (main): Likewise.
* doc/posix-functions/setenv.texi (setenv): Document this.
* doc/posix-functions/unsetenv.texi (unsetenv): Likewise.

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 '='.
