This is prepatory work for introducing more vpnor-specific behaviours to
window handling. We will be introducing more objects to link, in order
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.

The vpnor version needs to set the erase block size as 4K.
That's the size hostboot expects in the FFS structure.
This change also requires moving code from mboxd_flash.c to
mboxd_flash_physical.c, else there will be 3 symbols per flash function.
It should suffice to just have mboxd_flash_physical.c and
mboxd_flash_virtual.cpp.

Opens the partition file from the vpnor,
Memory map to it and then copy the given data
from the reserved memory area to the vpnor.

Map host's request to read the flash at offset less than the partition
table length as a request to read the pnor partition table.
Resolves openbmc/openbmc#1439.

Currently there is no output on the console unless -v is specified on
the command line which enables error output. A second -v will provide
info output.
We probably want error output irrespective of whether a -v was given
on the command line because people generally want to know why their
program stopped working.
Make error output unconditional.
A single -v will give minimal informational output which is a good
level to see what the daemon is doing without barfing all over the
console.
A second -v will enable debug output which will print highly verbose
information which will be useful for debugging. Probably don't enable
this under normal circumstances.

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.
