memory: Add Error** argument to the global_dirty_log routines

Now that the log_global*() handlers take an Error** parameter and
return a bool, do the same for memory_global_dirty_log_start() and
memory_global_dirty_log_stop(). The error is reported in the callers
for now and it will be propagated in the call stack in the next
changes.

To be noted a functional change in ram_init_bitmaps(), if the dirty
pages logger fails to start, there is no need to synchronize the dirty
pages bitmaps. colo_incoming_start_dirty_log() could be modified in a
similar way.

Modify all .log_global_start() handlers to take an Error** parameter

xen-hvm: reorganize xen-hvm and move common function to xen-hvm-common

This patch does following:
1. creates arch_handle_ioreq() and arch_xen_set_memory(). This is done in
preparation for moving

xen-hvm: reorganize xen-hvm and move common function to xen-hvm-common

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.

This is done to keep the common ioreq functions in one place which will be

hw/xen: Rename xen_common.h to xen_native.h

This header is now only for native Xen code, not PV backends that may be
used in Xen emulation. Since the toolstack libraries may depend on the
specific version of Xen headers that they pull in (and will set the
__XEN_TOOLS__ macro to enable internal definitions that they depend on),
the rule is that xen_native.h (and thus the toolstack library headers)
must be included *before* any of the headers in include/hw/xen/interface.
