85688d1c1a don't leak the channel list after all
unlike the actual configuration data, it's not kept in global variables,
so it shows up in memcheck.

09d11245cd don't leak box list from the command line
we also free the box list obtained from IMAP, so there isn't a real
reason not to do that for one from the command line.

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.

c84235b068 get rid of maildir_find_new_msgs() stub

38e7b4db22 Maildir: fix setting flags on messages without ":2," part
this is mostly hypothetical, as all messages i've encountered actually
have it even if no flags are set on them.

1004756659 kill TODO item about killing INBOX
while it's correct that mbsync doesn't strictly need to support both
Inbox and Path in a single Channel due to being able to Group Channels,
this "simplification" would have some undesirable effects:
- the concept is part of IMAP and provides a certain level of
  "zero-conf" (in particular via NAMESPACE). having to set up two Stores
  and associated Channels for one Account to reproduce this
  functionality would add quite some redundancy to common
  configurations.
- implementing MapInbox and move detection across Channels would add
  significant complexity.

one reason why one would want this change in the first place is to get
rid of the ambiguity of INBOX appearing right under Path. this could be
avoided by either using a different magic prefix that cannot appear in
actual mailbox names, or requiring a prefix for boxes inside path as
well. neither approach seems worth the effort, given that nesting
"INBOX" under Path causes problems for some other IMAP clients anyway.

f3629c69e1 autotest: re-organize mailbox storage by UID
an effect of 7ce658d is that we can index messages by UID rather than
content (or more specifically, subject). apart from being cleaner, it

ef2caa074e autotest: create the temp dir in $TEMP
on modern systems, this makes it likely to end up on tmpfs, which is a
lot faster and ssd-friendlier.

the symlink is not deleted at the end, to minimize fs churn. that means
it will be dangling after a reboot, which gets fixed in the next run.

30261fe6f1 fix version comparison in LibreSSL conditional
the operator was exactly inverted. that means that it actually wouldn't

the case as of 3.2).

542e38dd49 fix re-using server connections for new stores
we failed to reset the box list pointer after freeing it, which would
lead to a crash.
we also failed to reset the listing status, which would lead to
malfunction if we hadn't already crashed.

this inlines imap_cleanup_store(), as there isn't much value in keeping
it. the message list is already freed when disowning the store anyway.

813ad67c56 fix simultaneously connecting to multiple hosts in non-IPv6 builds
we need to deep-copy the struct hostent data, as otherwise the
concurrent connects will overwrite each other's lookup results.

this is a rather hypothetical fix, as the bug currently affects only
channels connecting two IMAP accounts, and only if the first host's
first address asynchronously fails to connect.

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.

94022a6752 catch server's failure to FETCH *
the query is untypical enough to have caused problems with davmail (when
we still used *:*) and mailo.com (until it got fixed), so better check
that the result (not) returned by the server makes sense.

dfa8c16f27 don't timeout while uploading big messages

far we did not reset it when succeeding to send out data. rectify that.
