This helps the export tool to deal with problems arising from message
assembly after everything has been successfully encrypted.
The original behavior is still available under `DecryptAndBuildRFC822`.
Incoming messages which arrive into labels we know during sync are now
presented to the IMAP clients.
We also allow messages to be deleted while syncing if deleted on other
clients.
Other operations such as moving, marking messages as read and label
operations need to be considered in a follow up patch as they are far
more complex.
The IMAP service no longer blocks the event loop from progressing. When
syncing the event loop continues as usual, allow other parts of the
bridge to continue updating.
Once the sync is complete, it resets the event id back to the last
handled id before sync started and then we play catch up.
* Fix wrong context use for message downloads
* Fix delete of sync data failing due ErrNotFound
* Pre-allocate attachment data buffer before download
* Fix calculation of progress if message count is higher than total
Update to latest Gluon to allow access to the database for bridge. The
cache is placed in a `SharedCache` type to ensure that we respect calls
to `Connector.Close`.
In theory, this should never trigger an error, but this way we can catch
it if it happens.

Add two separate toggles to control event loop pausing. This is required
to prevent cases where the bridge requests the event loop to be paused
but a sync process completes and resumes the event loop.
For the loop to resume now both states need to be set to false. This
will be removed once GODT-2848 is implemented.
Rather than having the services subscribe to each individual event type,
have only one subscriber for the whole event object. This spreads the
logic to the service through the `EventHandler` type.
This is important for the next stage where the IMAP service will be
required to apply events from the past.
Handles all IMAP related tasks. Unlike the previous iteration, this new
service automatically adds and removes users from Gluon by interfacing
with server manager.
