1. Balloon driver does not need to set M2P entry.
This is done by the populate_physmap hypercall.
2. Xen now translates foreign mappings from GMFN->MFN.
Tools are simplified because of this.

Actually the conflict between LAPIC ID 0x00 and IOAPIC ID 0x00
really doesn't matter even in a native system but we can avoid
any risk of a warning by shifting the LAPIC ID space by one.
Also the changeset fixes construction of the MADT (LAPIC info
was overwriting the IOAPIC info) so we can now boot with ACPI
MADT again.

In fdctrl_start_transfer the sector size field (fifo[5]) is not
checked for overflows. This allows an arbitrarily large sector size
to be used, which can in turn result in a negative data_len field that
is then used for DMA transfers.
This can lead to the corrpuption of qemu state because some subsequent
checks on the transfer length is conducted using signed integers.
This patch limits the value fifo[5] to 7 which is the standard limit
on floppy sector size.

1. Override ISA IRQs 5,6,10,11 as active-low level-triggered.
These are 'wired' to PCI devices.
2. Limit PCI-ISA link routers to route to 5,6,10,11. Others
are active-high edge-triggered and so invalid to use for
PCI devices. In any case, four ISA IRQs is sufficient to
avoid unnecessary aliasing among four links.
Also remove PCI device 0 IRQ info. It's an embedded host bridge with
no interrupt sources.

The Xen IPI spec states that destroy, hard_shutdown, pause, resume, start, suspend, and unpause return void. This patch makes it so and permits proper parsing of the response by clients (libxen) that follow the spec.

TODO:
1. Fix IO-APIC ID to not conflict with LAPIC IDS.
2. Fix i8259 device model (seems to work already though!).
3. Add INTSRC overrides in MPBIOS and ACPI tables so
that PCI legacy IRQ routing always ends up at an
IO-APIC input with level trigger. Restricting link
routing to {5,6,10,11} and setting overrides for all
four of those would work.

the vTPM device's state needs to be explicitly destroyed.
I am also surrounding the saving of the managed domain's configuration

that it logs everything written to stderr by xc_save and xc_restore as
errors whereas in fact the vast majority of this output is
information/debug (and all actual errors are marked by the string ERROR:
at the start of the message) -- this is confusing to folks looking at
the logs and makes automated log analysis tricky.
Fix is to scan for the ERROR: string and log anything without it using
log.info instead.

Fixed regression with rebooting domU caused by the change in handling
syncing state from Xen and Xend.
Added missing implementation for XendDomainInfo.unwatchVm() which
disappeared during a merge.
Added protection for console/vnc-port reading for managed domains.

As it stands the 8139C+ TX chaining is only bounded by realloc failure.
This is contrary to how the real hardware operates. It also has DoS
potential when ioemu runs in dom0.
This patch makes any attempt to chain a frame beyond 64K fail
immediately.
