usb: mtp: tag root property as experimental

Reason: we don't want commit to that interface yet.  Possibly
the implementation will be switched over to use fsdev.

docs: grammar fixes to qmp-events

When converting to qmp events, commits 7cfadb6b and a6330785
fixed some grammar as part of moving text between files.  But
since dfab4892 later restored this file to the state prior to
qmp events, we have to do it again.

SPICE_CONNECTED and SPICE_DISCONNECTED into separate qmp events.

docs: document missing SPICE_MIGRATE_COMPLETED event

The SPICE_MIGRATE_COMPLETED event was first documented in

docs: document missing VSERPORT_CHANGE event

The VSERPORT_CHANGE event was added in e2ae6159.  The patch for
this event was prepared at a time when this file was gone, even
though it got applied immediately after dfab4892 restored this

anyone using this file instead of qapi will not miss out on this

vnc update fix

We need to remember has_updates for each vnc client.  Otherwise it might
happen that vnc_update_client(has_dirty=1) takes the first exit due to
output buffers not being flushed yet and subsequent calls with
has_dirty=0 take the second exit, wrongly assuming there is nothing to
do because the work defered in the first call is ignored.

qemu-char: ignore flow control if a PTY's slave is not connected

After commit f702e62 (serial: change retry logic to avoid concurrency,
2014-07-11), guest boot hangs if the backend is an unconnected PTY.

The reason is that PTYs do not support G_IO_HUP, and serial_xmit is
never called.  To fix this, simply invoke serial_xmit immediately
(via g_idle_source_new) when this happens.
