Commit 757e725b58 added a number of #include "qemu/osdep.h"
files to the tcg-target.c files (as they were named at the time).
These are unnecessary because these files are not standalone C
files, and the tcg/tcg.c file which includes them will have
already included osdep.h on their behalf. Remove the unneeded
include directives.

Spice hooks the migration status changes to figure out when to
transmit information to the new spice server; but the migration
status in postcopy doesn't quite fit - the destination starts
running before the end of the source migration.
It's not a case of hanging off the migration status change to
postcopy-active either, since that happens before we stop the
guest CPU.
Fix it by sending a notify just after sending the device state,
and adding a flag that can be tested by the notify receiver.
Symptom:
spice handover doesn't work with the error:

This adds support for dma-buf passing to spice. This makes virtio-gpu
with 3d acceleration work with spice.
Workflow:
* virglrenderer renders the guest command stream into a texture.
* qemu exports the texture as dma-buf and passes on that dma-buf
to spice-server.
* spice-server passes the dma-buf to spice-client, using unix
socket file descriptor passing.
* spice-client asks the window systems composer to render the
dma-buf to the screen.
Requires cutting edge spice (server) and spice-gtk (client) builds,
from git master branch.
Also requires libvirt managing your qemu instance, and using
"virt-viewer --attach $guest". libvirt will connect spice-server and
spice-client using unix sockets instead of tcp sockets then, which
is required for file descriptor passing.
Works for the local case (spice server and client on the same machine)
only. Supporting remote too is planned (by feeding the dma-bufs into
gpu-assisted video encoder), but not there yet.
gl mode is turned off by default, use "-spice gl=on,$otherargs" to
enable it.

pid can be gotten from uhci device memory in uhci_handle_td(),
so the guest can trigger assert qemu if we get an invalid pid.
And the uhci spec 2.1.2 tells us The Host Controller sets Host
Controller Process Error bit to 1 when it detects a fatal error
and indicates that the Host Controller suffered a consistency
check failure while processing a Transfer Descriptor. An example
of a consistency check failure would be finding an illegal PID
field while processing the packet header portion of the TD.
When this error occurs, the Host Controller clears the Run/Stop
bit in the Command register to prevent further schedule execution.
We'd better to set UHCI_STS_HCPERR and kick an interrupt, check
the pid value at the first of uhci_handle_td function.
