These are not available under that name anymore and when the replacing extension has the same bare name, this would have led to duplicate capabilities.

lib-sieve: vnd.dovecot.report extension: Made the report action behave correctly when there is no envelope.

lib-sieve: enotify: mailto: Sending a notification still partly depended on having an envelope available.

This is used mainly when no other means of obtaining the user's email is available, such as when there is no envelope (in IMAP).
Before, the postmaster address or the null "<>" address was used as a fallback for sending messages.
The redirect and enotify commands can be explicitly configured to use what is configured with sieve_user_email.

Used wrong type in sizeof().

lib-sieve: Made sure local part of a mail address is encoded properly using quoted string when it is not a dot-atom.

lib-sieve: Allow X-Original-To header for the address test.

Trace_log variable was not initialized.

This way, imapsieve can show to which user.mailbox.uid the trace applies.

Registering conflicting commands before conflicts are checked is a bad idea.
Make sure conflicting extensions are not part of remaining validation process.

This was duplicated between the lda-sieve and imapsieve plugins.

lib-sieve: Implemented support for writing runtime trace output to a directory if it exists, much like Dovecot rawlog.

doc/example-config: Added description for a few generic settings that were only mentioned in the INSTALL file.

Futher changes are needed to prevent accessing the envelope in the first place.

It allows sending feedback report (RFC 5965) messages.

lib-sieve: Notify extensions about whether they are loaded in the validator optionally (ihave extension).

Conflicts are now always tested from both sides. This is mainly important for the "ihave" test.

An earlier change exposed this bug. Before, it was always a socket, and closing the output early meant using shutdown() rather than close().
This bug caused an assert failure.
