target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,
standards conformant hwaddr.
Outstanding patchsets can be fixed up with the command
git rebase -i --exec 'find -name "*.[ch]"
| xargs s/target_phys_addr_t/hwaddr/g' origin

In preparation of stopping to flush coalesced MMIO unconditionally on
vmexits, mark VGA MMIO and PIO regions as synchronous /wrt coalesced
MMIO and flush the buffer explicitly on PIO accesses that do not use
generic memory regions yet.

Zap the global VGA_RAM_SIZE #define, make the vga ram size configurable
for standard vga and vmware vga. cirrus and qxl are left with a fixed
size (and private VGA_RAM_SIZE #define) for now.
qxl needs some non-trivial adjustments in the mode list handling deal
with a runtime-configurable size, which calls for a separate qxl patch.
cirrus emulates cards which have 2 MB (isa) and 4 MB (pci), so I guess
it would make sense to use these sizes. That change would break
migration though, so I left it fixed at 8 MB size. Making it
configurabls is pretty pointless for cirrus as we have to match real
hardware.

Instead, use the bus accessors, or get the address space directly
from the board constructor.

Convert all vga memory to the memory API. Note we need to fall back to
get_system_memory(), since the various buses don't pass the vga window
as a memory region.
We no longer need to sync the dirty bitmap of the cirrus mapped memory
banks, since the memory API takes care of that for us.

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.
This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

When available, we'd like to be able to access the DeviceState
when registering a savevm. For buses with a get_dev_path()
function, this will allow us to create more unique savevm
id strings.

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
This reverts commit 99a0949b72.
