message_store: Add an each helper.

Browse Source 
This new helper allows us to do the same operation
on every message in our message_store.  We will
use this in a future commit to clear the `is_tall`
flags on all messages, after a resize.

We should be somewhat cautious about using this,
but simple operations should be really fast, even
if you have lots of messages in the store.
