Add a debouncer to the idle mode. Avoid unnecessary idling when another
job arrives within a certain time frame.
For example, the ui sends three messages to the worker at the same time
when we open a message (FlagMessage, FetchMessageBodyPart, and the
FetchMessageHeaders). The debouncer prevents the unnecessary entering
and leaving of the idle mode between those messages.

This happens because the flags are updated in the callback that receives
the message itself. It causes the flag update to arrive in the same
channel/request. Ignore the messages that have an empty body (i.e. only
containing flag updates). This is inherently racy but there seems no way
to get rid of these extra messages.

Ensure CRLF line endings in the pgpmail reader. Fix the pgp signature
verification for maildir and notmuch.
These backends do not return the full message body with CRLF
line endings. But the accepted OpenPGP convention is for signed data to
end with a <CR><LF> sequence (see RFC3156).
If this is not the case the signed and transmitted data are considered
not the same and thus signature verification fails.

introduced in commit beae17a6da ("imap: auto-reconnects on connection
error").
If a connection error is emitted, the message list is cleared and a
corresponding error message is shown in the ui. Status bar is updated as
well. Upon reconnect, the directories and the message list will be
re-fetched (same behavior as the connect command).
Reconnect can be enabled and disabled with the connect and the
disconnect commands.

already connected. The panic is caused by closing an already closed
channel. This happens when the idle re-init code is not executed, e.g.
when there's a return statement in the switch block. A defer func()
before the switch block will prevent this. The existing behavior of only
creating a new idleStop channel when properly connected is preseverd.

When using the notmuch backend, it often makes more sense to sort
folders (actual virtual folders, or queries) by the order specified in
the query-map file, rather than alphabetically. This patch introduces a
configuration option (disabled by default) that allows this.
Additionally, due to the notmuch backend previously using maps (which
are order-undefined) to store the list of queries, default query
selection on aerc startup fluctuated. This patch fixes that by using
slices to store query order.
Display threads in the message list. For now, only supported by the
notmuch backend and on IMAP when the server supports the THREAD
extension.
Setting threading-enable=true is global and will cause the message list
to be empty with maildir:// accounts.

In the maildir worker we manually need to track the Recent flag in order for the
notification command etc to work.
Push that responsibility to the container, we must make sure to manually add the
flag though if one grabs the message info.
We frequently had issues with notmuch segfaulting and my guess is that this
was due to the garbage collection magic used in the module.
This changes to a fork that ripped the functionality out.
We made a new type out of go-message/mail.Address without any real reason.
This suddenly made it necessary to convert from one to the other without actually
having any benefit whatsoever.
