  xhci: flush dequeue pointer to endpoint context

When done processing a endpoint ring we must update the dequeue pointer
in the endpoint context in guest memory.  This is needed to make sure
the guest has a correct view of things and also to make live migration
work properly, because xhci post_load restores alot of the state from
xhci data structures in guest memory.

Add xhci_set_ep_state() call to do that.

The recursive calls stopped by commit
ddb603ab6c981c1d67cb42266fc700c33e5b2d8f had the (unintentional) side
effect to hiding this bug.  xhci_set_ep_state() was called before
processing, to set the state to running, which updated the dequeue
pointer too.

  Fix input-linux reading from device

The evdev devices in input-linux.c are read in blocks of one whole
event. If there are not enough bytes available, they are discarded,
instead of being kept for the next read operation. This results in
lost events, of even non-working devices.

This patch keeps track of the number of bytes to be read to fill up
a whole event, and then handle it.

Changes from v1 to v2:
- Fix: Calculate offset on each iteration

Changes from v2 to v3:
- Fix coding style
- Store offset instead of bytes to be read

  vnc: allow to connect with add_client when -vnc none

Do not skip VNC initialization, in particular of auth method when vnc is
configured without sockets, since we should still allow connections
through QMP add_client.
