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.
we did already set up the timeout when starting to send commands, but so
far we did not reset it when succeeding to send out data. rectify that.

otherwise, we'd re-generate it during 'install' as well.
note that this does not work with new-style git worktrees, where .git is
only a file - but there the log generation itself already doesn't work
anyway.
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.
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.
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>.
while only 1KiB is required by the IMAP spec, AUTHENTICATE GSSAPI with
Kerberos requires about 1700 bytes.
accomodate that, plus some reserve.
fix suggested by Tollef Fog Heen <tfheen@err.no> via Debian BTS.
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.

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.

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 ...
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.
problem found by "Casper Ti. Vector" <caspervector@gmail.com>
apple gcc 4.2 complains about the use of the pragma inside a function.
clang also complains, but because the pragma is entirely unknown to it.
as neither compiler emits the bogus warning in the first place, there is
no point in suppressing it anyway.
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
typedefs (even to the same thing) is illegal before C11.
