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
compile with both older versions (that needed the aliases) and
potentially new versions (that will hide the data members - still not
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
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.

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>.
