Options

* sieve/{exitcodes.h hmac-md5.h md5.c md5.h md5global.h}: Removed. 

	* sieve/md5-rsa.c: New file, clear identiy that the algo.
	is from RSA and not GNU md5.
	* sieve/md5-rsa.h : New file.
	* sieve/Makefile.am:  added md5-rsa.[ch].
	* sieve/message.h:  lcase() change for strlower ().
	* sieve/script.c: Include md5-rsa.h.
	* sieve/sieve-gram.y: lcase changed for strlower ().
	* sieve/util.c: Remove all the unnecassary code and
	only implement strlower() and strupper().
	* sieve/util.h: Only export strlower and struppper ().

/* Sendmail has some weird ideas on what constitutes permenant failure. On
more than one occasion, we have gotten burned by this moving users around
through various inadvisable means, screwing up the mailboxes file,
whatever.
We don't want to fail out permenantly on things like EX_USAGE, EX_SOFTWARE,
etc., because that generally means someone was just screwing with the mail
store and we don't want to lose mail.
Instead, we map these EC_* codes to EX_* codes, thereby lying to Sendmail,
since we don't derive any benefit from Sendmail knowing what the error was.
We just want it to retry all the time anyway. This way, should sendmail's
behavior be different and we start deriving benefit from Sendmail knowing
stuff, we can easily change it back.
So other code uses the EC_* error, then we maybe change it to TEMPFAIL if
we don't agree on whether the error should be permenant or not.
