doveadm: dsync: Switch ioloop for input/output streams while making TCP connection.
This task is performed in a sub-ioloop, and when returning from that ioloop, the
output stream would sometimes still have an object on the sub-ioloop that was
just destroyed.

lib-ssl-iostream: openssl: Make verbose logging robust against i_debug() writing to stream itself.
In dsync, i_debug() is overridden to write to the SSL stream itself through a
multiplexed data stream. So, during the i_debug() call all kinds of things can
happen to the persisted error string in the stream, which caused problems.

fts: Fix searching headers with TEXT/BODY
TEXT is searching headers and BODY is searching MIME headers. Those headers
were indexed with data language, so search must also include data language
when looking up words. We'll just include the data language for all
searches now, so it should always work correctly.
imap: Iterate over ns settings when deciding to add SPECIAL-USE capability
To determine whether we should add the SPECIAL-USE capability to the
OK response to LOGIN, we have to iterate over namespace and mailbox
*settings* since the namespaces haven't been set up yet.

When the program_input is NULL, the stream is finished, meaning that the

remote streams, even when the program produces no output.

lib-index: Fix removal of forced cache decisions from existing cache files

imapc: Add imapc_features=no-msn-updates
This is a stricter version of fetch-msn-workarounds. The MSNs aren't trusted
at all. This means any new untagged EXISTS and EXPUNGE replies are ignored,
as well as untagged FETCH replies that don't include UID.
A potential downside with this feature is that UID FETCH/STORE commands
sent to expunged messages will likely fail without the IMAP client being
notified of the EXPUNGEs. New mails are also not noticed, so this should
be used only when it's known that the clients don't keep the connection
open for long.

lib-storage: mail_storage_set_index_error() - handle NULL index error
This avoids assert-crashing later on in mail*_get_last_internal_error().
This could potentially be an assert instead of setting it as "BUG", but
it looks like there are various code paths in lib-index that return -1
without setting an error. (That's to avoid duplicate error logging,
although it could now be fixed with mail_index_set_error_nolog().)

lib-storage: Set index error on transaction commit() callback
The commit callback is setting errors to storage. However, it's being
called from mail_index_transaction_commit() whose callers are expecting
the error to be in index. If that index error was attempted to be used,
it could have been wrong or NULL. Fix this by setting the same storage
error also to the index.
Including it in lib.h allows all of the Dovecot code (as well as any
external plugins) to just use these macros without worrying about what
system headers to include.

dsync: Add per-mailbox sync lock that is always used.
Both importing and exporting gets the lock before they even sync the
mailbox. The lock is kept until the import/export finishes. This guarantees
that no matter how dsync is run, two dsyncs can't be working on the same
mailbox at the same time.
This lock is in addition to the optional per-user lock enabled by the -l
parameter. If the -l parameter is used, the same lock timeout is used for
the per-mailbox lock. Otherwise 30s timeout is used.
This should help to avoid email duplication when replication is enabled for
public namespaces, and maybe in some other rare situations as well.
