only with "return" including "metadata". so clients can quickly get certain
metadata (eg for display, such as a color) for mailboxes.
this also adds a protocol token type "mailboxt" that properly encodes to utf7
if required.
this allows setting per-mailbox and per-server annotations (metadata). we have
a fixed maximum for total number of annotations (1000) and their total size
(1000000 bytes). this size isn't held against the regular quota for simplicity.
we send unsolicited metadata responses when a connection is in the idle
command and a change to a metadata item is made.
we currently only implement the /private/ namespace. we should implement the
/shared/ namespace, for mox-global metadata annotations. only the admin should
be able to configure those, probably through the config file, cli, or admin web
interface.

sensitive data or ddos'ing your log server.
the caveat is that the imap login command has already printed the line as
regular trace before we can decide it should not be. can be fixed soon.
