Handle TFTP ERROR from client

The ERROR packet should cause qemu to terminate the session. If not,
the sessions will soon run out and cause timeouts in the client.
Also, if a TFTP session already exists with same IP/UDP port, it

Support PCI based option rom loading
Currently, we preload option roms into the option rom space in memory. This
prevents DDIM from functioning correctly which severely limits the number
of roms we can support.
This patch introduces a pci_add_option_rom() which registers the
PCI_ROM_ADDRESS bar which points to our option rom. It also converts over
the cirrus vga adapter, the rtl8139, virtio, and the e1000 to use this
new mechanism.
The result is that PXE boot functions even with three unique types of cards.

Fix VMware VGA depth computation
VMware VGA requires that the depth presented to the guest is the same as the
DisplaySurface that it renders to. This is because it performs a very simple
memcpy() to blit from one surface to another.
We currently hardcode a 24-bit depth. The surface allocator for SDL may, and
usually will, allocate a surface with a different depth causing screen
corruption.
This changes the code to allocate the DisplaySurface before initializing the
device which allows the depth of the DisplaySurface to be used instead of
hardcoding something.

Make sure to enable dirty tracking of VBE vram mapping
Apparently, VBE maps the VGA vram to a fixed physical location. KVM requires
that all mappings of the VGA vram have dirty tracking enabled on them. Any
access to the VGA vram through the VBE mapping currently fails to result in
dirty page tracking updates causing a black screen.
This is the true root cause of VMware VGA not working correctly under KVM and
likely also an issue with some of the std-vga black screen issues too.
Cirrus does not enable VBE so it would not be a problem when using Cirrus.
