mailbox: Add ability for clients to request channels by name
This patch supplies a new framework API; mbox_request_channel_byname().
It works by supplying the usual client pointer as the first argument and
a string as the second. The API will search the client's node for a
'mbox-names' property then request a channel in the normal way using the
requested string's index as the expected second 'index' argument.
