doveadm: Send hostname without ":port" as TLS SNI name for outgoing SSL connections.

doveadm: Changed most print formatters to write to ostream. This allows all the formatters to be used when sending replies to the upcoming doveadm HTTP server responses. The "table" formatter wasn't modified, because it writes to both stdout and stderr.

dsync: Added tcps (TCP+SSL) target.

Array API changed: ARRAY_DEFINE(name, type) -> ARRAY(type) name Easy way to update your existing code: perl -i -pe 's:ARRAY_DEFINE\(([^,]+), *([^)]+)\);:ARRAY($2) $1;:' **/*.[ch]

doveadm: Added client/server architecture support for running mail commands. This is done when doveadm_worker_count is non-zero.
