d61f462039 Fix CopyArrivalDate on platforms without glibc
strptime(3)'s "%d" day of the month conversion specifier does not accept
leading blanks in case of single digit numbers.  "%e" does that.

While implementation details and differences between the two
day-of-month conversion specifiers vary, none of the major libcs
(incl. OpenBSD, FreeBSD, Illumos, musl) consume a leading blank for "%d"
except glibc, which consumes any number of spaces like in the "%e" case.

Using "%e" ensures that date strings like " 4-Mar-2018 16:49:25 -0500"
are successfully parsed by all major implementations in compliance to
X/Open Portability Guide Issue 4, Version 2 ("XPG4.2").  musl is now the
only one that still treats "%d" and "%e" without stripping any space.

Issue analysed and reported by Evan Silberman <evan@jklol.net> who found
mbsync 1.3.0 on OpenBSD 6.4 to fail with `CopyArrivalDate' set when
syncing mails with the above mentioned timestamp.

See https://marc.info/?l=openbsd-tech&m=155044284526535 for details.

a8f6eebdd9 Work around useless SASL warnings
Ater sasl_client_step() is called and the Cyrus SASL library forwards
it to the client plugin, if the result value is OK (authentication
succeeded), the clientout is filled out to be an empty string, even if
the client plugin wanted to return NULL.

To avoid that mbsync complains at this point, check the returned length
instead of the pointer.

acfa3a2bbc sort messages from UID FETCH request
turns out that some IMAP servers (e.g., poczta.o2.pl) do not return
messages in ascending UID order in response to a UID FETCH request,
which makes the driver violate the API contract.

counter this by sorting the messages. this also addresses the
long-standing (but hypothetical) issue that parallel UID FETCH requests
could be handled out-of-order and thus also lead to mixed up results.

based on patch by Marcin Niestroj <macius1990w@gmail.com>.

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.

c29eceaeed make map_name() interpret empty strings as "no separator"
empty strings were previously meaningless, and starting with 72c2d695a,
failure to handle them lead to bogus results when the IMAP hierarchy
separator is legitimately empty (when the server genuinely supports none
and none is manually configured). non-null can be asserted more cleanly
than null-or-non-empty, so change the api like that.
incidentally, this also removes the need to work around gcc's bogus
warning in -Os mode.

5aab050198 don't forward-declare SSL types any more
our current project structure precludes the clash between some indirect
include of ssl.h and our definition of 'S' (or 'M', i don't remember)
that happened on some system, so there is no need to avoid including it
any more.

this avoids complaints from some more picky compilers, as re-defining

56515abe94 socket: use next addrinfo if opening socket fails
The `socket_connect_one` function previously did an `exit(1)` when
encountering any errors with opening the socket. This would break
connecting to a host where multiple possible addrinfos are returned,
where the leading addrinfos are in fact impossible to connect to. E.g.
with a kernel configured without support for IPv6, the `getaddrinfo`
call may still return a hint containing an IPv6 address alongside
another hint with an IPv4 address. Creating the socket with the IPv6
address, which will cause an error, lead us to exiting early without
even trying remaining hints.

While one can argue that the user should have compiled without HAVE_IPV6
or used an appropriate DNS configuration, we can do better by simply
skipping over the current addrinfo causing an error. To do so, we split
out a new function `socket_connect_next`, which selects the next
available address info and subsequently calls `socket_connect_one`
again. When no hints remain, `sock_connect_one` will error out at that
point.

bd5fb6fff3 move away from magic UIDs in the sync state
the only legitimate "deviant" UID is zero, meaning "no message". this
can be futher qualified by additional flags in the sync record, rather
than using magic values for the UID. in fact, the zero UID (so far
meaning only "expunged") was already optionally qualifed with "expired".

as a side effect, driver->store_msg() now returns 0 instead of -2 for
unknown UIDs. this was a hack to avoid translating the value later
on, but it made the api horrible, and now it's superflous in the first
place.

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.

we need a separate log entry type which does proper mmaxxuid tracking.

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

amends b1842617.

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.

af4b8896f0 use typedefs for structs more
makes the code more compact (and consistent, as typedefs were already
used in some places).

1fdf793a3f fix signedness of 'nex' variables
they are derived from srec->status, which is unsigned. for not
understood reasons, the compiler complains only after extending status
to a full unsigned int.

on the way, localize the declarations.

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.

d754608f55 autotest: improve valgrind integration
introduce recognition of $USE_VALGRIND to run all mbsync invocations
through valgrind.

this also removes the seemingly purposeless --log-fd=3 indirection.
