This patch fixes:
1. build error in xen_pt.c when XEN_PT_LOGGING_ENABLED is defined
2. debug output format string error when DEBUG_XEN is defined

In the second case I also have the output info in consistent with the
output in mapping function - that is, print start_addr instead of
phys_offset.

Qemu has several hardcoded xenstore paths that are only valid on Dom0.
Attempts to launch a Qemu instance (to act as a userspace backend for
PV disks) will fail because Qemu is not able to access those paths
when running on a domain different than Dom0.

Instead make the xenstore paths relative to the domain where Qemu is
actually running.

Add ref/unref calls at the following places:

- places where memory regions are stashed by a listener and
  used outside the BQL (including in Xen or KVM).

- memory_region_find callsites

- creation of aliases and containers (only the aliased/contained
  region gets a reference to avoid loops)

- around calls to del_subregion/add_subregion, where the region
  could disappear after the first call

This reverts commit 9f24a803.

The start of the PCI hole is actually set to 0xf0000000 by hvmloader.
In order to retain ABI compatibility with Xen we leave the start of the
PCI hole at 0xf0000000 in QEMU (for Xen) too.

So far, the size of all regions passed to listeners could fit in 64 bits,
because artificial regions (containers and aliases) are eliminated by
the memory core, leaving only device regions which have reasonable sizes

An IOMMU however cannot be eliminated by the memory core, and may have
an artificial size, hence we may need 65 bits to represent its size.

No need for xen_vcpu_init anymore:

- the RTC emulator doesn't have any periodic timers continuously running

Many of these should be cleaned up with proper qdev-/QOM-ification.

Use the global first_cpu variable to halt the CPU rather than using a
local first_cpu initialized from qemu_get_cpu(0).

This will allow to change qemu_get_cpu() return type to CPUState
