f1f5f4070c Add SPICE support to add_client monitor command
With the acceptance of some new APIs to libspice-server.so it
is possible to add support for SPICE to the 'add_client'
monitor command, bringing parity with VNC. Since SPICE can
use TLS or plain connections, the command also gains a new
'tls' parameter to specify whether TLS should be attempted
on the injected client sockets.

This new feature is only enabled if building against a
libspice-server >= 0.10.1

* qmp-commands.hx: Add 'tls' parameter & missing doc for
  'skipauth' parameter
* monitor.c: Wire up SPICE for 'add_client' command
* ui/qemu-spice.h, ui/spice-core.c: Add qemu_spice_display_add_client
  API to wire up from monitor

    http://cgit.freedesktop.org/spice/spice/commit/server/spice.h?id=bd07dde530d9504e1cfe7ed5837fc00c26f36716

Changes in v3:
 - Added 'optional' flag to new parameters documented
 - Added no-op impl of qemu_spice_display_add_client when
   SPICE is disabled during build

7844e448d1 qxl: don't render stuff when the vm is stopped.
This patch fixes the local qxl renderer to not kick spice-server
in case the vm is stopped.  First it is largely pointless because
we ask spice-server to process all not-yet processed commands when
the vm is stopped, so there isn't much do do anyway.  Second we
avoid triggering an assert in spice-server.

The patch makes sure we still honor redraw requests, even if we don't
ask spice-server for updates.  This is needed to handle displaysurface
changes with a stopped vm correctly.

With this patch applied it is possible to take screen shots (via
screendump monitor command) from a qxl gpu even in case the guest
is stopped.

99c7f87826 input: send kbd+mouse events only to running guests.
Trying to interact with a stopped guest will queue up the events,
then send them all at once when the guest continues running, with
a high chance to have them cause unwanted actions.

Avoid that by only injecting the input events only when the guest
is in running state.

aa24822bdc i8259: Do not clear level-triggered lines in IRR on init

pcspk_callback but with a much cleaner interface. Also, it will simplify

ce967e2f33 i8254: Rework & fix interaction with HPET in legacy mode
When the HPET enters legacy mode, the IRQ output of the PIT is
suppressed and replaced by the HPET timer 0. But the current code to
emulate this was broken in many ways. It reset the PIT state after
re-enabling, it worked against a stale static PIT structure, and it did
not properly saved/restored the IRQ output mask in the PIT vmstate.

This patch solves the PIT IRQ control in a different way. On x86, it
both redirects the PIT IRQ to the HPET, just like the RTC. But it also
keeps the control line from the HPET to the PIT. This allows to disable
the PIT QEMU timer when it is not needed. The PIT's view on the control
line state is now saved in the same format that qemu-kvm is already
using.

Note that, in contrast to the suppressed RTC IRQ line, we do not need to
save/restore the PIT line state in the HPET. As we trigger a PIT IRQ
update via the control line, the line state is reconstructed on mode
switch.

319ba9f527 i8254: Pass alternative IRQ output object on initialization
HPET legacy emulation will require control over the PIT IRQ output. To
enable this, add support for an alternative IRQ output object to the PIT
factory function. If the isa_irq number is < 0, this object will be
used.

This also removes the IRQ number property from the PIT class as we now
use a generic GPIO output pin that is connected by the factory function.

5904ae4eba hpet: Save/restore cached RTC IRQ level
In legacy mode, the HPET suppresses the RTC interrupt delivery via IRQ
8 but keeps track of the RTC output level and applies it when legacy
mode is turned off again. This value has to be preserved across save/
restore as it cannot be reconstructed otherwise.

To document that a raised rtc_irq_level won't survive a vmload without
a hpet/rtc_irq_level subsection, add an explicit clearing to the reset
handler.

7dfbfc7927 vnc: Don't demote authentication scheme when changing password/disabling login
Currently when disabling login in VNC, the password is cleared out and the
authentication protocol is forced to AUTH_VNC.  If you're using a stronger
authentication protocol, this has the effect of downgrading your security
protocol.

Fix this by only changing the authentication protocol if the current
authentication protocol is AUTH_NONE.  That ensures we're never downgrading.

4ed658ca92 qdev: Fix qdev_try_create() semantics
Since QOM'ification, qdev_try_create() uses object_new() internally,
which asserts "type != NULL" when the type is not registered.
This was revealed by the combination of kvmclock's kvm_enabled() check
and early QOM type registration.

Check whether the class exists before calling object_new(), so that
the caller (e.g., qdev_create) can fail gracefully, telling us which
device could not be created.

cf904cfa7c qemu-queue: drop QCIRCLEQ
The main advantage of circular lists (the fact that the head node
has the same memory layout as any other node) is completely negated
by the implementation in qemu-queue.h.  Not surprisingly, nobody
uses QCIRCLEQ.  While this might change if RCU is ever adopted by
QEMU, the QLIST is also RCU-friendly and in fact it is used in a
RCU-like manner by 9pfs already.  So, just kill QCIRCLEQ.

9faf31b68f do not chdir(/) in qemu-nbd before opening all files
When qemu-nbd becomes a daemon it calls daemon(3) with
nochdir=0, so daemon(3) changes current directory to /.
But at this time, qemu-nbd did not open any user-specified
files yet, so by changing current directory, all non-absolute
paths becomes wrong.  The solution is to pass nochdir=1 to
daemon(3) function, and to chdir("/") after all init has
been performed, before entering the main loop, -- just like
a good daemon should do.

This patch is applicable for -stable.

case (Linux): if the daughterboard has a CLCD it will come first
