Wait is capped at 16s. Prevents many reconnect attemps in a short time period.
Fixes commit 05ad96a30c ("imap: improve reconnect stability") that
improved the reliability of the reconnect mechanism but did not
implement controls to prevent the triggering of too many reconnects
within a short period of time.

improves the robustness of the imap reconnect feature which was
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.

Some messages contain invalid headers, textproto.ReadHeader fails with
an error:
malformed MIME header key: From nobody Fri Jan 14 19
And all other messages of the selected folder are ignored.
Return an explicit error message to the UI and continue processing other
messages. This is consistent with what the maildir worker does.

Since commit 01c96e78df ("Update DirectoryInfo handling for maildir"),
flags are checked for every message of a folder when entering it.
Iterating over all messages of a folder takes a long time for large
collections of emails.
Only count the number of messages and state that the directory info
counts are not accurate. Defer the parsing of message flags in
a goroutine to have a more responsive UI.

Previously, Message.NewReader returned the wrapped buffered reader
without a reference to the opened file, so the files descriptors
were left unclosed after reading. Now, the file reader is returned
directly and closed on the call site. Buffering is not needed here
because it is an implementation detail of go-message.

fixes the panic when the user sends multiple connect commands and is
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.

Use the Client.LoggedOut() channel which is closed when the connection

When a maildir is synchronized by an external process while aerc is
running (e.g. mbsync), some emails may be moved out of "new" to "cur" or
completely deleted.
These deletions are ignored and aerc may assume these messages are still
here, leading to errors.
Take file deletions into account. Also, add "cur" to the watched
folders since these can be modified as well.

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.
This commit gets rid of the additional type
This change handles message parse errors by printing the error when the
user tries to view the message. Specifically only handling unknown
charset errors in this patch, but there are many types of invalid
messages that can be handled in this way.
aerc currently leaves certain messages in the msglist in the pending
(spinner) state, and I'm unable to view or modify the message. aerc also
only prints parse errors with message when they are initially loaded.
This UX is a little better, because you can still see the header info
about the message, and if you try to view it, you will see the specific
error.
This allows us to hook into the std libs implementation of parsing related stuff.
For this, we need to get rid of the distinction between a mailbox and a host
to just a single "address" field.
However this is already the common case. All but one users immediately
concatenated the mbox/domain to a single address.
So this in effects makes it simpler for most cases and we simply do the
transformation in the special case.
The `:rmdir` command removes the current directory (`-f` is required if
the directory is not empty).
This is not supported on the notmuch backend.
An issue with the maildir backend is that some sync programs (e.g.
offlineimap) may recover the directory after it is deleted. They need
to specifically be configured to accept deletions, or special commands
need to be executed (e.g. `offlineimap --delete-folder`) to properly
delete folders.
A danger of using this on the IMAP backend is that it is possible for a
new message to be added to the directory and for aerc to not show it
immediately (due to a slow connection) - using `:rmdir` at this moment
(with `-f` if the directory already contains messages) would delete the
directory and the new message that just arrived (and all other
contents). This is documented in aerc(1) so that users are aware of
possible risks.
If a message date would fail to parse, the worker would never receive
the MessageInfo it asked for, and so it wouldn't display the message.
The problem is the spec for date formats is too lax, so trying to ensure
we can parse every weird date format out there is not a strategy we want
to pursue. On the other hand, preventing the user from reading and
working with a message due to the error format is also not a solution.
The maildir and notmuch workers will now fallback to the internal date, which
is based on the received header if we can't parse the format of the Date header.
The UI will also fallback to the received header whenever the date header can't
be parsed.
This patch is based on the work done by Lyudmil Angelov <lyudmilangelov@gmail.com>
But tries to handle a parsing error a bit more gracefully instead of just returning
the zero date.
If accounts.conf contains an invalid maildir url, return a nice
error instead of panicking.
Log a couple of different error cases to provide extra
information about the error to the user.
Aerc usually used the path []int{1} if it didn't know what the proper path is.
However this only works for multipart messages and breaks if it isn't one.
This patch removes all the hard coding and extracts the necessary helpers to lib.
Provide search and filter with the option to specify more flag based
conditions.
Use '-x <flag>' to search for messages with a flag (seen, answered,
flagged) and '-X <flag>' to search for messages without a flag.
