Attach the usb bus of a new pvusb controller to the qdev associated
with the Xen backend. Any device connected to that controller can now
specify the bus and port directly via its properties.

PAGE_SIZE is undefined on ARM64. Use XC_PAGE_SIZE instead, which is
always 4096 even when page granularity is 64K.
For this to actually work with 64K pages, more changes are required.

When unplugging a device in the Xen pvusb backend drain the submit
queue before deallocation of the control structures. Otherwise there
will be bogus memory accesses when I/O contracts are finished.
Correlated to this issue is the handling of cancel requests: a packet
cancelled will still lead to the call of complete, so add a flag
to the request indicating it should be just dropped on complete.

Tracked down with an ugly, brittle and probably buggy Perl script.
Also move includes converted to <...> up so they get included before
ours where that's obviously okay.

qemu/osdep.h checks whether MAP_ANONYMOUS is defined, but this check
is bogus without a previous inclusion of sys/mman.h. Include it in
sysemu/os-posix.h and remove it from everywhere else.

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

Add a backend for para-virtualized USB devices for xen domains.
The backend is using host-libusb to forward USB requests from a
domain via libusb to the real device(s) passed through.
