xen-disk: use an IOThread per instance
This patch allocates an IOThread object for each xen_disk instance and
sets the AIO context appropriately on connect. This allows processing
of I/O to proceed in parallel.
The patch also adds tracepoints into xen_disk to make it possible to
follow the state transtions of an instance in the log.

xenfb: Use Input Handlers directly
Avoid the unneccessary calls through the input-legacy.c file by
using the qemu_input_handler_*() calls directly. This did require
reworking the event and sync handlers to use the reverse mapping
from qcode to linux using qemu_input_qcode_to_linux().
Removes the scancode2linux mapping, and supporting documention.

xenfb: Add [feature|request]-raw-pointer
Writes "feature-raw-pointer" during init to indicate the backend
can pass raw unscaled values for absolute axes to the frontend.
Frontends set "request-raw-pointer" to indicate the backend should
not attempt to scale absolute values to console size.
"request-raw-pointer" is only valid if "request-abs-pointer" is
also set. Raw unscaled pointer values are in the range [0, 0x7fff]
"feature-raw-pointer" and "request-raw-pointer" added to Xen
header in commit 7868654ff7fe5e4a2eeae2b277644fa884a5031e

xenfb: activate input handlers for raw pointer devices
If the frontend requests raw pointers, the input handlers must be
activated to have the input events delivered to the xenfb backend.
Without activation, the input events are delivered to handlers
registered earlier, which would be the emulated USB tablet or
emulated PS/2 mouse.
HVM xen_kbdfront can incorrectly scale absolute coordinates when
the display resolution is not 800x600.

xen/pt: Set is_express to avoid out-of-bounds write
The passed-through device might be an express device. In this case the
old code allocated a too small emulated config space in
pci_config_alloc() since pci_config_size() returned the size for a
non-express device. This leads to an out-of-bound write in
xen_pt_config_reg_init(), which sometimes results in crashes. So set
is_express as already done for KVM in vfio-pci.
