Instead of the target-specific TARGET_PAGE_BITS definition,
use qemu_target_page_bits() which is target agnostic.

To avoid a potential global variable shadow in
hw/i386/pc_piix.c::pc_init1(), rename Xen's
"ram_memory" as "xen_memory".

According to the QEMU Coding Style document:
> Do not use printf(), fprintf() or monitor_printf(). Instead, use
> error_report() or error_vreport() from error-report.h. This ensures the
> error is reported in the right place (current monitor or stderr), and in
> a uniform format.
> Use error_printf() & friends to print additional information.
This commit changes fprintfs that report warnings and errors to the
appropriate report functions.

Tracing DPRINTFs to stderr might not be desired. A developer that relies
on tracepoints should be able to opt-in to each tracepoint and rely on
QEMU's log redirection, instead of stderr by default.
This commit converts DPRINTFs in this file that are used for tracing
into tracepoints.

When a vm transitions from running to suspended, runstate notifiers are
not called, so the notifiers still think the vm is running. Hence, when
we call vm_start to restore the suspended state, we call vm_state_notify
with running=1. However, some notifiers check for RUN_STATE_RUNNING.
They must check the running boolean instead.
No functional change.

Coverity points out (CID 1513106, 1513107) that MemoryListener is a
192 byte struct which we are passing around by value. Switch to
passing a const pointer into xen_register_ioreq() and then to
xen_do_ioreq_register(). We can also make the file-scope
MemoryListener variables const, since nothing changes them.

On ARM it is possible to have a functioning xenpv machine with only the
PV backends and no IOREQ server. If the IOREQ server creation fails continue
to the PV backends initialization.
Also, moved the IOREQ registration and mapping subroutine to new function
xen_do_ioreq_register().

This patch does following:
1. creates arch_handle_ioreq() and arch_xen_set_memory(). This is done in
preparation for moving most of xen-hvm code to an arch-neutral location,
move the x86-specific portion of xen_set_memory to arch_xen_set_memory.
Also, move handle_vmport_ioreq to arch_handle_ioreq.
2. Pure code movement: move common functions to hw/xen/xen-hvm-common.c
Extract common functionalities from hw/i386/xen/xen-hvm.c and move them to
hw/xen/xen-hvm-common.c. These common functions are useful for creating
an IOREQ server.
xen_hvm_init_pc() contains the architecture independent code for creating
and mapping a IOREQ server, connecting memory and IO listeners, initializing
a xen bus and registering backends. Moved this common xen code to a new
function xen_register_ioreq() which can be used by both x86 and ARM machines.
Following functions are moved to hw/xen/xen-hvm-common.c:
xen_vcpu_eport(), xen_vcpu_ioreq(), xen_ram_alloc(), xen_set_memory(),
xen_region_add(), xen_region_del(), xen_io_add(), xen_io_del(),
xen_device_realize(), xen_device_unrealize(),
cpu_get_ioreq_from_shared_memory(), cpu_get_ioreq(), do_inp(),
do_outp(), rw_phys_req_item(), read_phys_req_item(),
write_phys_req_item(), cpu_ioreq_pio(), cpu_ioreq_move(),
cpu_ioreq_config(), handle_ioreq(), handle_buffered_iopage(),
handle_buffered_io(), cpu_handle_ioreq(), xen_main_loop_prepare(),
xen_hvm_change_state_handler(), xen_exit_notifier(),
xen_map_ioreq_server(), destroy_hvm_domain() and
xen_shutdown_fatal_error()
3. Removed static type from below functions:
1. xen_region_add()
2. xen_region_del()
3. xen_io_add()
4. xen_io_del()
5. xen_device_realize()
6. xen_device_unrealize()
7. xen_hvm_change_state_handler()
8. cpu_ioreq_pio()
9. xen_exit_notifier()
4. Replace TARGET_PAGE_SIZE with XC_PAGE_SIZE to match the page side with Xen.
