mboxd: Add a backend abstraction layer to mboxd.

Introduce a backend abstraction, enabling multiple implementations to be
compiled in at once. This change formally abstracts the two existing
backends, mtd and vpnor.

With the backend abstraction in place, subsequent backends are easier to
implement.

This change is based of Evan's work and he retains authorship credit. I
(AJ) have reworked the patch to pass the vpnor tests, refactored some
parts to enable broader use of const structures and others to clarify
the initialisation sequences.

Due to the existing lack of abstraction the patch has unfortunately
wide-ranging impacts. I've whittled it down as much as I consider
reasonable.

flash: Introduce flash_validate()

Clean up the protocol_negotiate_version() mess. The existing approach
came about due to viewing the vpnor implementation as an edge case in
its own right. The code becomes much neater if we consider all backends
as equal and afford them the callbacks necessary for correct behaviour.

vpnor: Hijack protocol rather than transport

By hijacking the transport the changes in behaviour were limited to the
mailbox interface. Now that we have a DBus interface as well this would
lead to inconsistent behaviour dependent on the transport.

Instead of hooking the transport, push the hook down to the protocol
level where we will achieve consistent behaviour across all transports.

vpnor: Configure a handler table in init_vpnor()

Currently the table just mirrors that which is set by the regular
implementation, however getting to that point requires massaging the
code a little. Thus, separate out this change from one that changes the
behaviour of the commands to improve the readability of the latter
change.

This is prepatory work for introducing more vpnor-specific behaviours to

to hook some of the window command handlers.

This change takes the opportunity to revert back to the upstream names
for some of the original C files.
