Standalone binlog server

The idea is to have something like

mysqld --defaults-extra-file=/etc/some.cnf --binlog-server --datadir=/path/to/my/binlogs/ --port=6033 --repl-user=markus --repl-password=s3kr3t

So you can easily start and stop an standalone instance that has no real datadir, and instead only has the binlogs one would need to perform point in time recovery. One should only specify the binlogs dir, port, user and passwords necessary for a replication slave thread to connect to it.

The use case is for a Point In Time Recovery, specially if one has streamed binlogs to backup server... Having a standalone, easy to setup binlog-server would prevent DBAs from having to copy binlogs elsewhere, avoid dumping the binlogs and avoid all the potential issues that can happen when importing a binlog dump.
