search for: maildir_unlink_dirname

Hello, I am currently working on a patch to add IMAPdir support to dovecot. (For those who do not know, IMAPdir is exactly like Maildir except that instead of having a folder .foo it would just be foo. The advantage is that the file system is slightly easier to search through without the dot in front of the folders.) The first thing I did was get the configuration file working for Maildir.
