Explicit read/write locking pidfile under WIN32 is bit extreme
nobody get the chance to read the pidfile. Convert to a write-only lock.
Also, creating pidfile was disabled along with daemonize under
WIN32. Enable it, but do not enable daemon support which doesn't
exist under WIN32 atm.

Now that we load the option roms via fw_cfg, we can stop copying
them to the 0xc000 -> 0xe000. The patch does just that.
Also the rom loader gets simplified as all remaining users of the
rom loader load the bits at a fixed address so the packing and
aligning logic can go away.

This patch adds a file transfer interface to fw_cfg. Intended to be
used for passing non-pci option roms and vgabios to seabios. Namespace
is modeled after the existing cbfs filesystem support in seabios.
Reading the new FW_CFG_FILE_DIR entry returns a file list.
Fields there are in network byte order (aka bigendian).
aliguori: fix fw_cfg.h for multiboot.bin, add proper fw_cfg.h declarations,
quiet fprintf() in fw_cfg.c

This patch adds a romfile property to the pci bus. It allows to specify
a romfile to load into the rom bar of the pci device. The default value
comes from a new field in PCIDeviceInfo. The property allows to change
the file and also to disable the rom loading using an empty string.

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.

SCSI controllers have no trouble existing without any attached
disks. This could be achieved with the (legacy) monitor syntax
pci_add pci_addr=auto storage if=scsi
This is now denied with
scsi requires a backing file/device.

There is no need for this denial and it breaks compatability
with existing QEMU usage, so remove the check for presence

This patch enables dirty log tracking whenever it's needed and disables it
when it is not.
We unconditionally enable dirty log tracking on reset, restart dirty log
tracking when PCI IO regions are remapped, and disable/enable it based on
commands from the guest.

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.

This is needed for VMware VGA to work properly under KVM.

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.

The monitor_vprintf() function now touches the 'mon' pointer
before calling monitor_puts(), this causes block migration
to segfault as its functions call monitor_printf() with a
NULL 'mon'.
To fix the problem this commit moves the 'mon' NULL check
from monitor_puts() to monitor_vprintf().
This can potentially hide bugs, but for some reason this has
been the behavior for a long time.

Currently we always set the "config space changed" bit to 1 when triggering
any virtio interrupt. While that worked in 2.6.27, newer kernels interpret
that value as "only the config space changed and nothing else happened".
Since we usually trigger interrupts to tell the guest that something did
happen, we just not tell it the config space changed for now until we
implement the correct callback for that.

We were being a bit too nice and didn't give the guest an invalid instruction
interrupt.
While that works, it's not exactly the fastest thing to do, since now the
guest doesn't know that we're not really implementing that instruction, so it
continues doing it.
We run into this with the set_page_unstable hint instruction. So let's bail out
in these cases.

If QEMU finds newer kernel header files on compilation time, it will use
advertised features like pipe2 or SOCK_CLOEXEC by just doing a compile test.
If later the executables are executed on an older kernel (<2.6.27,
like Xen Dom0 2.6.18), then QEMU will fail on opening sockets and creating
pipes and returns the rather unspecific "qemu_init_main_loop failed".
This patch fixes this by checking the return values of these calls
for EINVAL and ENOSYS and falling back to the older versions automatically.
