d624c9af5d make set_bad_callback() a proper driver_t entry
... and make the pointers private to the drivers.

f46cf8c887 provide a proper getter callback for driver capabilities
that way driver_t contains only callbacks.

d54809e268 prepend "get_" to getters in driver_t
this makes it callbacks consistently start with a verb.

36666f7e52 rewrite tracking of highest expired UID
so far, we tracked the slave side, and calculated the master side on the
fly. that complicated things unnecessarily.

677accfd84 streamline syncing of old entries
the order of the conditionals was purely historical (pre 4ec56f8cf, anno
2005) and hard to follow, as were the comments.

990c8a1404 sort uid exception list in a smarter place
do it closer to where it is populated. that way the debug output is
sorted, and we don't sort the list if it's known to be empty.

72be55b0e3 add fallbacks for determining UIDNEXT
if the server sends no UIDNEXT, do an initial FETCH to query the UID of
the last message.

same if the server sends no APPENDUID.

this allows us to remove the arbitrary limitation of the UID range to
INT_MAX, at the cost of additional round-trips.

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.

b9505301cc factor out listing Maildir++ Stores
Maildir++ is sufficiently different from the other SubFolder styles to
justify a separate function; the resulting code duplication is minimal,
but the separated functions are a lot clearer.

9eaa97923a fix exclusion of bogus "INBOX.*" folders in Maildir++
this also adds code which avoids that the message about excluding the
mailbox is printed multiple times - this could happen with Maildir++, as
the hierarchy is flattened.

amends 0f24ca31b.

2d1cfc2c7f make "Patterns *" match INBOX* in Maildir++ Stores
this also has the side effect that we won't fail to include INBOX itself
when Inbox is nested under Path when using other SubFolder styles
(regression introduced with Maildir++ support in 0f24ca31b).

34993fbca6 fix sync resumption with aborted entries
we need a separate log entry type which does proper mmaxxuid tracking.

while moving code around, this also removes a redundant debug statement.

887b2205ff remove nonsensical statement from journal replay of aborted entries
at this stage, entries cannot possibly have messages assigned to them,
so trying to unlink them makes no sense.

5c2ce59217 fix sync resumption with re-newed messages
the UID of the entries needs to be bumped from -1 to -2, as otherwise
the resumed run would see a TUID in a sync entry which may not have one.

1ea2e69aa7 fix maxuid tracking
newmaxuid represents the highest UID for which a sync entry was created,
while maxuid represents the end of the range which is guaranteed to have
been propagated. that means that the former needs to be instantly
incremented (and logged), while the latter must not be touched until the
entire new message sync completes. this matters particularly in the case
of resuming an interrupted run, where sync entry creation must resume
exactly where it left off, while loading the box must use the old limit
to ensure that all messages are available for actual propagation.

6705604c4a de-duplicate journal replay somewhat
we've been using indices to separate master/slave state for a long time,
so there is no point in using pairs of matching brackets to signify the
side in the journal. instead, use somewhat descriptive letters (S[een],
F[ind], T[rashed]) and the index itself.

1fdf793a3f fix signedness of 'nex' variables
they are derived from srec->status, which is unsigned. for not

to a full unsigned int.

1e939bafd8 don't use strncpy() to copy TUIDs
latest since 77acc268, the code prior to these statements ensures that
the full length is available, so just use memcpy(). the code for
comparing TUIDs uses memcmp() anyway.

67f4aeff1f standardize on 'int' for message sizes
that's what the sources already assumed anyway. size_t is total
overkill, as No Email Ever (TM) will exceed 2GiB.

this also fixes a harmless format string warning in 32 bit builds.
