From: Stefano Stabellini
This is done to prepare for enabling xenpv support for ARM architecture.
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.

xen-mapcache.c contains common functions which can be used for enabling Xen on
aarch64 with IOREQ handling. Moving it out from hw/i386/xen to hw/xen to make it
accessible for both aarch64 and x86.

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.

In preparation to moving most of xen-hvm code to an arch-neutral location, move:
- shared_vmport_page
- log_for_dirtybit
- dirty_bitmap
- suspend
- wakeup

related to dirty logging.
