Previous change "maildir: hide invalid folders" prevents filepath.Walk
from descending into directories that don't contain new/, tmp/ or cur/
because the WalkDirFunc returns filepath.SkipDir.
We have to assume that these directories can be the parent of valid
maildir folders even if they're not themselves valid maildir folders, so
it is a mistake not to recurse into these subfolders. Fix it by
returning nil instead of filepath.SkipDir in the WalkDirFunc.

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.

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.

Implement MoveMessages in the maildir worker. go-maildir supports Move
operations by default, and is functionally equivalent to a OS-level
rename. Creation date of the file is preserved by using Move, which is
used by at least one maildir-to-IMAP synchronizer (isync/mbsync). The
previous move method of copy-and-delete would reset the creation date of
the message, and potentially cause sorting issues in other email
clients.

Apply GoDoc comment policy (comments for humans should have a space
after the //; machine-readable comments shouldn't)
Use strings.ReplaceAll instead of strings.Replace when appropriate
Remove if/else chains by replacing them with switches
Use short assignment/increment notation
Replace single case switches with if statements
Combine else and if when appropriate

Do not pass logger objects around anymore. Shuffle some messages to make
them consistent with the new logging API. Avoid using %v when a more
specific verb exists for the argument types.
The loggers are completely disabled (i.e. Sprintf is not even called)
by default. They are only enabled when redirecting stdout to a file.

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.
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.
Add the initial implementation of a backend for Maildir accounts. Much
of the functionality required is implemented in the go-message and
go-maildir libraries, so we use them as much as possible.
The maildir worker hooks into a new maildir:// URL scheme in the
accounts.conf file which points to a container of several maildir
directories. From there, the OpenDirectory, FetchDirectoryContents, etc
messages work on subdirectories. This is implemented as a Container
struct which handles mapping between the symbolic email folder names and
UIDs to the concrete directories and file names.
