Update to Dovecot 1.0.10.

v1.0.8 and v1.0.9 were a bit bad releases. Hopefully one day I've managed to
have written a proper test suite which can be run before doing any releases..

	* Security hole with LDAP+auth cache: If base setting contained
	  %variables they weren't included in auth cache key, which broke
	  caching. This could have caused different users with same passwords
	  to log in as each other. [pkgsrc: this was fixed in dovecot-1.0.9nb1]

	- LDAP: Fixed potential infinite looping when connection to LDAP
	  server was lost and there were queued requests.
	- mbox: More changes to fix problems caused by v1.0.8 and v1.0.9.
	- Maildir: Fixed a UIDLIST_IS_LOCKED() assert-crash in some conditions
	  (caused by changes in v1.0.9)
	- If protocols=none, don't require imap executables to exist
