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 allows us to provide alternative implementations for the handlers
as necessary. The vpnor feature, which enforces the read-only property
of FFS partitions, requires this for handling CREATE_WRITE_WINDOW.

mboxd_msg.h uses the MBOX_REG_BYTES symbol, but forces its users to
first include mbox.h. Include what we use to restore some sanity.

This was roughly achieved by the following shell script:
$ git ls-files |
grep '\.[ch]p*$' |
while read F; do EXT=${F##*.}; cat spdx.$EXT <(sed '/^\/\*$/,/^ \*\/$/d' $F) > ${F}.tmp; mv ${F}.tmp $F; done

The `sed` invocation catches a lot of function documentation, so the
hunks were manually added to avoid removing information that we want to
keep.

The previous patch added a new return field in GET_MBOX_INFO called
"suggested timeout" to be used to provide a suggested maximum timeout
value to the host.
Add this to the return arguments of GET_MBOX_INFO.
Note that the host is free to ignore the value and the daemon can
leave this blank if it doesn't want to provide a timeout.
We hard code a milliseconds per megabyte value which was determined
to be approximately 8000 based on testing and is close to linear
as the access size changes. Testing was conducted on an Aspeed ast2500
on a Witherspoon with the dev-4.7 OpenBMC branch.

Version 2 of the mbox protocol contains a few changes such as:
- All sizes are in block size
- Adds an erase command
- Adds new response codes
- Adds new BMC events
- Open windows commands now take a size directive
Update the mailbox daemon to support version 2 of the protocol which
includes implementing all of the V2 functionality. Also entirely refactor
the mboxd.c code to make it more modular improving readability and
maintainability.
At the same time improve the functionality by adding:
- Multiple windows in the daemon (still only one active window) to cache
flash contents
- Implement a dbus interface to allow interaction with the daemon
- Handle sigterm and sigint and terminate cleanly
The previous implementation utilised the entire reserved memory region.
Update the daemon so that on the command line the number of windows and
the size of each which the reserved memory region will be split into can
be specified. The reserved memory region is then divided between the
windows, however there can still only be one "active" window at a time.
The daemon uses these windows to cache the flash contents meaning the
flash doesn't have to be copied when the host requests access assuming
the daemon already has a copy.
A dbus interface is added so that commands can be sent to the daemon to
control it's operation from the bmc. These include suspending and resuming
the daemon to synchronise flash access, telling the daemon to point the lpc
mapping back to flash and telling the daemon when the flash has been
modified out from under it.
