QRESYNC and CONDSTORE just pushed

[Kevin J. McCarthy]

I've just pushed CONDSTORE and (experimental) QRESYNC IMAP support into
master.

If you run against an IMAP server that supports QRESYNC, I would
greatly appreciate help testing.

(Note that Gmail doesn't seem to benefit from either of these
extensions. Enabling CONDSTORE in fact seems to slow Gmail down.)

Performance boost is a second or two on 33k+ mailbox (I use lmdb and M.2
SSD for caching). Thank you for this patch, it improves things.

Thanks Consus!

By the way (for the list), I neglected to mention the extensions are
enabled by the config vars $imap_condstore and $imap_qresync, which
default unset.

For CONDSTORE, Mutt is only using the FETCH CHANGEDSINCE extension, not
the conditional store or other features. On servers which don't include
MODSEQ in the initial UID FETCH (where it is not required), this can
result in a slight speedup due to the flags not being included.

QRESYNC can result in a larger speedup because it can completely skip
the initial UID FETCH.

With sleep_time set to 0 the switch is almost instant now ^_____^

I just realized I left a stupid mistake in the code, so please hold off
on testing until I push a fix later this morning. I'll post when it's
fixed.

Okay, I've pushed up a fix. Testers, please pull and rebuild asap.

The brain is a strange thing. I meant to include that guard quite a
while ago, but forgot in the midst of the refactor. Then last night I
suddenly woke up and realized I had forgotten! :-o

Anyway, I'm sure this won't be the last issue, but I'll try to get fixes
pushed as quickly as I can for testers.
