Remove sieve action string

We use sieve to forward messages to a notification
daemon which can send SMSes, and we don't want them
filled with information about the actions which
Sieve took.

This patch stops the action_string being appended to
the message sent to the notify daemon.
GUID IMAP COMMANDS

This patch factors out stuff we used to have in the old MD5UUIDs
patch, the following FETCH responses in imapd:

FETCH DIGEST.SHA1 => 40 character hex string (message sha1)
FETCH RFC822.SHA1 => 40 character hex string (message sha1, calculated)
FETCH RFC822.FILESIZE => size of actual file on disk (via stat or mmap)

It also adds a capability string item: "DIGEST=SHA1"

Totally non-standard of course, but way useful for our replication checking
scripts.  Embrace and extend 'r' us.

Anyone feel like writing an RFC for fetching the digest of a message via
IMAP?  If the server calculated it on delivery and cached it then you'd have
a great way to clean up after a UIDVALIDITY change or other destabilising event
without having to fetch every message again.

Add conversations database.

It's a very simple database with only one type of record, which
maps a message-id with angle brackets, e.g. "<0001@example.com>",
to a conversation id and a timestamp.  The conversation id is a
64b int.

struct conversations_state holds a reference to an open conversations
database.  There can be more than one of these in existance.  There
will eventually be a conversations databases per-user, but this code
doesn't know that and just takes a filename.

conversations_open() opens a database handle and starts a transaction.

conversations_close() aborts the transation if it has not been
    commited, and closes the database handle.

conversations_commit() commits a transaction.

conversations_set() stores a conversation id for a msgid, and sets
    the record's timestamp to the current system time.

conversations_get() retrieves the conversation id given a msgid.

conversations_prune() removes all records older than a given time.

Add mailbox actions file.

This is a file where actions can be posted, that are then later executed
by the first process to open the mailbox with an exclusive lock.  A
fcntl lock is used to provide exclusion between writers to file file,
and to detect when a writer has lost a race with an opener (who renames
the actions file before excuting the actions therein).  Actions are
simple lines of text.

Currently only a single action is implemented, the NOP action which just
increments a count.  This is for testing purposes.

The purpose of the mechanism is to allow delayed renaming of CIDs in
mailbox index files.
