pt_bar_reg_parse() is called for expansion rom base address register.
Currently it returns PT_BAR_FLAG_MEM if bit 0 is 0. It returns
PT_BAR_FLAG_IO if bit 0 is 1.
But bit 0 in expansion rom base address register is enable bit. If bit
0 is 1 for some reason, it returns PT_BAR_FLAG_IO. Expansion rom is
mapped to memory space. It should return PT_BAR_FLAG_MEM.
After applying this patch, it returns PT_BAR_FLAG_MEM regardless
of bit 0, when it is called for expansion rom base address register.

I forgot to shift value read from real device. If the emulated
register offset is not aligned with 4 byte, the write emulation will
not be handled well because of corrupting register value read from
real device. The patch fixes this issue.

libpci returns ALL F when error occurs. Currently, if libpci returns
ALL F, emulation stops. But it is possible that the field of real register
which is read by guest software is ALL F.
After applying this patch, if libpci returns ALL F, ioemu will log
warning message and continue the emulation.

This patch fixes writing handlers for base address registers (include
expansion rom base address register) as follows.
It can be applied to both ioemu-remote and ioemu.
- Current implementation can not work fine when base address registers
are accessed via 1 byte write access and 2 byte write access. This
patch enables them.
- Currently guest software can set address which is not aligned
with resource size and page size. The patch does not allow guest
software to set unaligned address.

The new merged qemu no longer has the ability to spawn a vnc viewer
process in the bowels of the xend/qemu stack. In this patch we
provide support for this use case in a different manner - one more
akin to the mechanism used for `xm console' and `xm create -c'.
We introduce new xm options:
xm create --vncviewer [--vncviewer-autopass]
xm vncviewer [--vncviewer-autopass]
These spawn a VNC viewer, obtaining the relevant information
(including the port number and if you tell it your viewer supports it
the password to use) directly from xenstore.
Like xm console it waits in the foreground for the vnc port to become
available; the timeout case isn't handled as well as it might be - it
just causes the whole program (xm) to die with `Alarm clock' but this
is difficult to deal with given the current structure of the xs Python
lowlevel interface, which doesn't provide a timeout on the call to
wait for a xenstore watch.

If put dom0 RMRR check in domain_context_unmap_one(), the devices with
RMRR cannot be assigned to other domain, becuase
domain_context_unmap_one() won't unmap context for them, and dom0
always owns them. This patch moves the check to intel_iommu_remove_device()
which is only called by dom0 hypercall. This not only guarantees
keeping RMRR mappings for dom0 during its booting, but also won't
impact device assignment.

Currently if someone changes the date on the host, xenconsoled may
behave incorrectly due to the use of gettimeofday for the rate control
algorithm. For example I was able to hang the console connected to a
guest just setting the date forward 20 years. To solve the problem we
need to use a time source that doesn't change start point, that is
clock_gettime with CLOCK_MONOTONIC. The only bad side effect is that
it introduces a dependency to librt, but I think is well worth it.
