emacs: show: improve handling of mark read tagging errors
Previously if a marking read tag change (i.e., removing the unread
tag) failed for some reason, such as a locked database, then no more
mark read tag changes would be attempted in that buffer.
This handles the error more gracefully. There is not much we can do
yet about dealing with the error itself, and marking read is probably
not important enough to warrant keeping a queue of pending changes or
anything.
However this commit changes it so that
- we do try and make future mark read tag changes.
- we display the tag state correctly: i.e. we don't display the tag as
deleted (no strike through)
- and since we know the tag change failed we can try to mark this
message read in the future. Indeed, since the code uses the
post-command hook we will try again on the next keypress (unless the
user has left the message).
We indicate to the user that these mark read tag changes may have
failed in the header-line.

fix thread breakage via ghost-on-removal
implement ghost-on-removal, the solution to T590-thread-breakage.sh
that just adds a ghost message after removing each message.
It leaks information about whether we've ever seen a given message id,
but it's a fairly simple implementation.
Note that _resolve_message_id_to_thread_id already introduces new
message_ids to the database, so i think just searching for a given
message ID may introduce the same metadata leakage.

test thread breakage when messages are removed and re-added
This test (T590-thread-breakage.sh) has known-broken subtests.
If you have a two-message thread where message "B" is in-reply-to "A",
notmuch rightly sees this as a single thread.
But if you:
* remove "A" from the message store
* run "notmuch new"
* add "A" back into the message store
* re-run "notmuch new"
Then notmuch sees the messages as distinct threads.
This happens because if you insert "B" initially (before anything is
known about "A"), then a "ghost message" gets added to the database in
reference to "A" that is in the same thread, which "A" takes over when
it appears.
But if "A" is subsequently removed, no ghost message is retained, so
when "A" appears, it is treated as a new thread.
I see a few options to fix this:
ghost-on-removal
----------------
We could unilaterally add a ghost upon message removal. This has a
few disadvantages: the message index would leak information about what
messages the user has ever been exposed to, and we also create a
perpetually-growing dataset -- the ghosts can never be removed.
ghost-on-removal-when-shared-thread-exists
------------------------------------------
We could add a ghost upon message removal iff there are other
non-ghost messages with the same thread ID.
We'd also need to remove all ghost messages that share a thread when
the last non-ghost message in that thread is removed.
This still has a bit of information leakage, though: the message index
would reveal that i've seen a newer message in a thread, even if i had
deleted it from my message store
track-dependencies
------------------
rather than a simple "ghost-message" we could store all the (A,B)
message-reference pairs internally, showing which messages A reference
which other messages B.
Then removal of message X would require deleting all message-reference
pairs (X,B), and only deleting a ghost message if no (A,X) reference
pair exists.
This requires modifying the database by adding a new and fairly weird
table that would need to be indexed by both columns. I don't know
whether xapian has nice ways to do that.
scan-dependencies
-----------------
Without modifying the database, we could do something less efficient.
Upon removal of message X, we could scan the headers of all non-ghost
messages that share a thread with X. If any of those messages refers
to X, we would add a ghost message. If none of them do, then we would
just drop X entirely from the table.
---------------------
One risk of attempted fixes to this problem is that we could fail to
remove the search term indexes entirely. This test contains
additional subtests to guard against that.
This test also ensures that the right number of ghost messages exist
in each situation; this will help us ensure we don't accumulate ghosts
indefinitely or leak too much information about what messages we've
seen or not seen, while still making it easy to reassemble threads
when messages come in out-of-order.

lib: fix handling of one character long directory names at top level
The code to skip multiple slashes in _notmuch_database_split_path()
skips back one character too much. This is compensated by a +1 in the
length parameter to the strndup() call. Mostly this works fine, but if
the path is to a file under a top level directory with one character
long name, the directory part is mistaken to be part of the file name
(slash == path in code). The returned directory name will be the empty
string and the basename will be the full path, breaking the indexing
logic in notmuch new.
Fix the multiple slash skipping to keep the slash variable pointing at
the last slash, and adjust strndup() accordingly.
