Better hashing for cyrus-imapd-2.0.7

[Gary Mills]

I'm testing cyrus-imapd-2.0.7, and I notice that the userid hashing
scheme in conf/deliverdb, conf/quota, and conf/user use the first
letter of the userid for subdirectory names.  Unfortunately, we have
about 20,000 userids that begin with the string `um', which will all
hash to the same directory.  Where can I find a better hashing scheme?
