Plugin core: support true multi-node multi-master replication of dovecot

dovecot syncer plugin

helps to create scripts for true multi-node multi-master replication

plugin listens on mailbox changes and reports them by:

• writing a marker file <mail_home>/syncer/guid/<mailbox_guid>
• sending a change event to the pipe /run/dovecot/syncer/pipe

replication scripts then can watch for changes:

• new files in the syncer/{guid,type} folder
• new events in the syncer/pipe fifo

and invoke doveadm sync -g <mailbox_guid> to multiple replication nodes

replication design

use tinc symmetric mail network mesh

have tinc-up / tinc-down script dynamically register mail replication nodes

have your replication scripts to use tinc dynamic nodes as replication targets

plugin installation
