df22514ced turn maildir_again() into a proper varargs function
this is mostly to work around the fact that both gcc and clang won't
accept the format string declaration (i.e., will complain with
-Wformat-nonliteral) if the *called* function does not actually take a
va_list.

on the upside, it makes one caller cleaner. yay ...

83adb9a39b actually implement maildir_get_uidnext()
the assumption was that this wouldn't be needed, as maildir_store_msg()
reliably delivers a UID. however, if we crash right before the callback
can record that UID, we'd still use OPEN_FIND in the next run, which
requires the saved next UID.

04fc586e75 handle case-insensitivity of IMAP's INBOX
this is relevant only when listing an IMAP Store's contents, as that's
the only place where we aren't imposing the spelling ourselves.

we need to be careful not to treat our own canonical (prefix-stripped
and always slash-delimited) box names like that; codify that in
comments.

this reveals that commit 6f2160f1 may be deemed to have been incorrect -
the TODO item was ambiguous, and could quite possibly have meant this
fix. unsurprisingly, 380ccdd4 re-introduced it with more explicit
wording.

e565d08246 don't try to propagate flags the target store does not support
$Forwarded is not standard, so it will most likely fail with mailboxes
that do not support keywords.

c4d7f0189c implement Forwarded flag
maildir supports a 'P' flag which denotes the fact that a message has
been 'passed' on (forwarded, bounced). notmuch syncs this to the
'passed' tag.

Per https://tools.ietf.org/html/rfc5788, IMAP has a user-defined flag
(keyword) '$Forwarded' that is supported by many servers and clients
these days. (Technically, one should check for '$Forwarded' in the
server response.)

Restructure mbsync's flag parser to accept keywords (flags starting with
'$') but still bail out on unknown system flags (flags starting with '\').
Support '$Forwarded' as a first keyword since it maps to maildir's 'P'
and needs to be sorted in between the system flags.

e71f0ccc2a mark MAILBOX_DRIVER_FLAG locations in code
Mailbox driver flags are defined in several places. It is essential that
they are kept in sync, so mark them with the same string for easy
grepping with an alerting boiler plate.

5072032939 fix uidvalidity recovery with really long message-id headers
re-using the file name buffer for the headers wasn't such a great idea,
as _POSIX_PATH_MAX is only 256, while RFC2822 permits lines up to 1000
chars. and sure enough, i have a message with a whopping 470-char
message-id header ...

416ced25dd fix repeated listing of same Store with different flags
multiple Channels can call driver_t::list_store() with different LIST_*
flags. assuming the flags are actually taken into consideration, using a
single boolean 'listed' flag to track whether the Store still needs to
be listed obviously wouldn't cut it - if INBOX does not live right under
Path and the Channels used entirely disjoint Patterns (say, * and
INBOX*), the second Channel in a single run (probably a Group) would
fail to match anything.

to fix this, make store_t::listed more granular. this also requires
moving its handling back into the drivers (thus reverting c66afdc0),
because the actually performed queries and their possible implicit
results are driver-specific.

note that this slightly pessimizes some cases - e.g., an IMAP Store with
Path "" will now list the entire namespace even if there is only one
Channel with Pattern "INBOX*" (because a hypothetical Pattern "*" would
also include INBOX*, and the queries are kept disjoint to avoid the need
for de-duplication). this isn't expected to be a problem, as listing
mailboxes is generally cheap.

0f24ca31b5 fix SubFolders style Maildir++
turns out i misread the spec in a subtle way: while all other folders
are physically nested under INBOX, the IMAP view puts them at the same
(root) level. to get them shown as subfolders of INBOX, they need to
have _two_ leading dots.

this also implies that the Maildir++ mode has no use for a Path, so
reject attempts to specify one.

cda596d530 remove legacy (bsd-style) locking
flock() may be implemented via fcntl(), which may cause the process to
deadlock itself when trying to apply both types of locks. this is the
case even on linux when the file lives on NFS.

it's unlikely that anything except mbsync would try to access the
.uidvalidity files anyway, so there is no point in trying to be
compatible with anything else ...

17f3348ff1 make it possible to specifiy Pattern INBOX* with no Path defined
that pattern may very well expand to INBOXNOT, which would naturally
live under Path, so we need to look into the Path. of course, this
actually makes sense only if there *is* a Path, and complaining about
it being absent is backwards.
