Thomas Gleixner 05ac7bb6ac remail/pipe: Add command line option to handle config updates
When using pipe mode configuration updates are not handled until the next
mail is sent to the list. That means that e.g. welcome mails are delayed.

Add a command line option to allow the invocation of remail_pipe just to
deal with configuration updates without trying to process mail from stdin.

The update handling is serialized against concurrent incoming mail via the
folder lock, so no extra serialization is required. Whichever comes first
handles it.
