Fixes updating the flags in the imap backend. Before, the silent flag
was set incorrectly by 75fc42e ("imap: send message info updates for
bulk flag ops") which caused some imap servers to not send the updated
flags. By disabling the silent flag, the flag update will return a
corrsponding value that we can send back to the message store to update
the flags correctly.

Add option to open a message in the message viewer without setting the
seen flag. Enables the message viewer to be used as a preview pane
without changing the message flags unintentionally. Before, the message
viewer would set the seen flag by default. The IMAP backend will now
always fetch the message body with the peek option enabled (same as we
fetch the headers).
An "auto-mark-read" option is added to the ui config which is set to
true by default. If set the false, the seen flag is not set by the
message viewer.

The worker uses a buffered channel to queue tasks. Buffered channels
are effective at FIFO, but are prone to blocking. The design of aerc is
such that the UI must always accept a response from the backends, and
the backends must always accept a request from the UI. By using buffered
channels for both of these communication channels, a deadlock will
occur.
Break the chain by using a doubly linked list (container/list from the
standard library) to queue tasks for the worker. Essentially, this is an
infinitely buffered channel - but more memory efficient as it can change
size dynamically.

The maildir worker currently populates the list of mail folders by
listing all the filesystem subdirectories in the maildir directory.
Although there's no official specification for maildir subfolders,
they should all have cur/ new/ and tmp/ subdirectories to be valid.
This patch prevents directories that don't have those subdirectories
present on the filesystem from appearing in the account folder list.
This is useful for example to prevent ".notmuch" and ".notmuch/xapian"
from showing up in the folder list if using notmuch to index emails
while using aerc's maildir backend.

Add XOAUTH2 authentication support for IMAP and SMTP. Although XOAUTH2
is now deprecated in favor of OAuthBearer, it is the only way to connect
to Office365 since Basic Auth is now completely removed.
Since XOAUTH2 is very similar to OAuthBearer and uses the same
configuration parameters, this is basically a copy-paste of the existing
OAuthBearer code.
However, XOAUTH2 support was removed from go-sasl library, so this
change reimports the code that was removed from go-sasl and offers it
a new home in lib/xoauth2.go. Hopefully it shouldn't be too hard to
maintain, being less than 50 SLOC.

When an error is encountered fetching a header, the backends respond
with a type.Error worker message. On receipt of this message, the UI
deletes all pending headers. The headers are all requested again as they
remain on the screen, resulting in an infinite request loop - and an
infinite logging loop. The user only ever sees the spinner unless they
check the logs.
A previous commit intended to fix this, however it introduced a
regression where any message that was part of the fetch request would
also be marked as erroneous. This commit is reverted with commit
2aad2fea7d36 ("msgstore: revert 9fdc7acf5b48").

When cached headers are fetched, an action is posted back to the Worker
to immediately fetch the flags for the message from the server (we can't
know the flags state, therefore it's not cached). When scrolling, a lag
occurs when loading cached headers because the n+1 message has to wait
for the flag request to return before the cached headers are retrieved.
Collect the message UIDs in the UI that need flags, and fetch them based
off a debounce timer in a single request. Post the action from the UI to
eliminate an (ugly) go routine in the worker.

The built-in maildir.Dir.Move method performs an OS level file rename,
which allows for preserving file creation time. Commit c98f704874
("move: enable MoveMessages from msgstore") enabled the use of the Move
method for maildir. One particular maildir synchronizer (isync/mbsync)
encodes the UID within the filename of the email and cannot recover if
the UID is preserved during a move. mbsync encodes filenames like so:
/path/to/email/{maildir-key},U={uid}:2,S
OfflineIMAP encodes the UID within the filename, but also encodes a hash
of the originating folder so that it can recover from a move without a
rename of the underlying file. OfflineIMAP encodes like so:
/path/to/email{maildir-key},U={uid},FMD5={folder-hash}:2,S
Remove encoded UIDs of the form `,U={uid}` from filenames to prevent
sync issues.

When there is no Date header in a message, aerc falls back to the
Received header and tries to extract an rfc1123z date from it
(introduced in commit d1600e46). The current regex for extracting the
date incorrectly allows for trailing whitespace, causing time.Parse() to
fail inside of parseReceivedHeader(). As a result, the message's date is
shown as "???????????????????" in the message list and as
"0000-12-31 07:03 PM" in the message view (the latter is likely related
to the zero value of time.Time).
Steps to reproduce:
1) Send yourself a message with no Date header, e.g. with msmtp:
printf 'Subject: foo bar\n\nbody text\n' | msmtp --set-date-header=off me@example.com
2) Note the message's displayed date in aerc's message list and message

The imap worker's seqmap is represented as a map of sequence number to
UID. This presents a problem when expunging group of messages from the
mailbox: each individual expunge decrements the sequence numbers by 1
(for every sequence number greater than the expunged). This requires a
looping around the map to update the keys. The use of a map also
requires that both the sequence number and the UID of a message be known
in order to insert it into the map. This is only discovered by fetching
individual message body parts (flags, headers, etc), leaving the seqmap
to be empty until we have fetched information about each message. In
certain instances (if a mailbox has recently been loaded), all
information is loaded in memory and no new information is fetched -
leaving the seqmap empty and the UI out of sync with the worker.
Refactor the seqmap as a slice, so that any expunge automatically
decrements the rest of the sequences.
Use the results of FetchDirectoryContents or FetchDirectoryThreaded to
initialize the seqmap with all discovered UIDs. Sort the UIDs in
ascending order: IMAP specification requires that sequence numbers start
at 1 increase in order of ascending UID.
Add individual messages to the map if they come via a MessageUpdate and
have a sequence number larger than our slice.
Update seqmap tests with new logic.
