a76a2f729a spice: fix libvirt snapshots
Only notify spice-server about migration events in case we got
target host information beforehand.  So we kick the seamless spice
client migration only in case a actual live migration happens, not
when libvirt uses live-migration-to-file for snapshotting.

4f60af9ac0 spice: fix "info spice"
In case no listening address was specified, "info spice" reports
"0.0.0.0" as address.  Which is incorrect in case spice is listening
on ipv6.  Replace it by a wildcard "*" to indicate it is not limited
to a specific address.

Note:  Being more specific is not possible without extending the
spice-server api.  The socket is handled by spice-server not
qemu, so qemu can't easily figure the actual socket address.

f1d3e586f0 spice: flip streaming video mode to off by default
Video streaming detection heuristics in spice-server have problems
keeping modern desktop animations (as done by gnome shell) and real
video playback apart.  This leads to jpeg compression artefacts on
your desktop, due to spice using mjpeg to send what it thinks is
a video stream.

Turn off video detection by default to avoid these artifacts.

9fa032866d spice: fix multihead support
This patch fixes spice display initialization to handle
multihead properly.

spice-core now keeps track of which QemuConsole has a spice
display channel attached to it and which has not.  It also
manages display channel ids.

spice-display looks at all QemuConsoles and will pick up any
graphic console not yet bound to a spice channel (which in practice
are all non-qxl graphic devices).

Result is that
 (a) you'll get a spice client window for each graphical device
     now (first only without this patch), and
 (b) mixing qxl and non-qxl vga cards works properly.

764eb39d1b Fix VNC SASL authentication when using a QXL device
ui/vnc.c:vnc_display_open() and spice-server/server/reds.c:do_spice_init()
are both calling sasl_server_init(). If spice_server_set_sasl_appname()
hasn't been called, spice-server will call it with "spice" as an appname,
causing cyrus-sasl to try to use a /etc/sasl2/spice.conf config file rather
than the /etc/sasl2/qemu.conf file that QEMU uses.

When using -spice sasl on the command line, QEMU properly calls
spice_server_set_sasl_appname() to set the SASL appname as "qemu",
but when using a QXL device without using SPICE, spice_server_init()
is called from qemu_spice_add_interface() without setting the appname
to "qemu", which then causes the VNC code to try to use spice.conf
instead of qemu.conf.

58ae52a8dc spice: fix display initialization
Spice has two display interface implementations:  One integrated into
the qxl graphics card, and one generic which can operate with every
qemu-emulated graphics card.

The generic one is activated in case spice is used without qxl.  The
logic for that only caught the "-vga qxl" case, "-device qxl-vga" goes
unnoticed.  Fix that by adding a check in the spice interface
registration so we'll notice the qxl card no matter how it is created.

02edd2e766 migration: fix spice migration
Commit 29ae8a4133 ("rdma: introduce
MIG_STATE_NONE and change MIG_STATE_SETUP state transition") changed the
state transitions during migration setup.

Spice used to be notified with MIG_STATE_ACTIVE and it detected this
using migration_is_active().  Spice is now notified with
MIG_STATE_SETUP and migration_is_active() no longer works.

Replace migration_is_active() with migration_in_setup() to fix spice
migration.

67be6726b6 spice: raise requirement to 0.12
With the next qemu version (1.3) we are going to bump the qxl device
revision to 4.  The new features available require a recent spice-server
version, so raise up the bar.  Otherwise we would end up with different
qxl revisions depending on the spice-server version installed, which
would be a major PITA when it comes to compat properties.

Clear out a big bunch of #ifdefs which are not needed any more.

2fdd16e239 spice migration: add QEVENT_SPICE_MIGRATE_COMPLETED
When migrating, libvirt queries the migration status, and upon migration
completions, it closes the migration src. On the other hand, when
migration is completed, spice transfers data from the src to destination
via the client. This data is required for keeping the spice session
after migration, without suffering from data loss and inconsistencies.
In order to allow this data transfer, we add QEVENT for signaling
libvirt that spice migration has completed, and libvirt needs to wait
for this event before quitting the src process.

835cab85ad spice: abort on invalid streaming cmdline params
When parsing its command line parameters, spice aborts when it
finds unexpected values, except for the 'streaming-video' option.
This happens because the parsing of the parameters for this option
is done using the 'name2enum' helper, which does not error out
on unknown values. Using the 'parse_name' helper makes sure we
error out in this case. Looking at git history, the use of
'name2enum' instead of 'parse_name' seems to have been an oversight,
so let's change to that now.

ad1be89948 spice: fix broken initialization
Commit 1b71f7c14f moved MODULE_INIT_QOM to
way before MODULE_INIT_MACHINE, thereby breaking assumptions made in
spice-core.c which registered both a type initializer and a machine

This fix removes the type registration, and replaces it with calling
qemu_spice_init in vl.c after command line parsing (second pass) is
done, and after timers are armed, required by spice server.

012b80d3f9 spice: require spice 0.6.0 or newer.
This patch raises the minimum required spice version to 0.6.0 and drops
a few ifdefs.

0.6.0 is the first stable release with the current libspice-server API,
there shouldn't be any 0.5.x development versions deployed any more.

48b3ed0a68 spice: add SASL support
Turn on SASL support by appending "sasl" to the spice arguments, which
requires that the client use SASL to authenticate with the spice.  The
exact choice of authentication method used is controlled from the
system / user's SASL configuration file for the 'qemu' service. This
is typically found in /etc/sasl2/qemu.conf. If running QEMU as an
unprivileged user, an environment variable SASL_CONF_PATH can be used
to make it search alternate locations for the service config.  While
some SASL auth methods can also provide data encryption (eg GSSAPI),
it is recommended that SASL always be combined with the 'tls' and
'x509' settings to enable use of SSL and server certificates. This
ensures a data encryption preventing compromise of authentication
credentials.

It requires support from spice 0.8.1.

7bd427d801 change all rt_clock references to use millisecond resolution accessors
This was done with:

    sed -i '/get_clock\>.*rt_clock/s/get_clock\>/get_clock_ms/' \
        $(git grep -l 'get_clock\>.*rt_clock' )
    sed -i '/new_timer\>.*rt_clock/s/new_timer\>/new_timer_ms/' \
        $(git grep -l 'new_timer\>.*rt_clock' )

after checking that get_clock and new_timer never occur twice
on the same line.  There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.

e866e23959 spice/vnc: client migration.
Handle spice client migration, i.e. inform a spice client connected
about the new host and connection parameters, so it can move over the
connection automatically.

The monitor command has a not-yet used protocol argument simliar to
set_password and expire_password commands.  This allows to add a simliar
feature to vnc in the future.  Daniel Berrange plans to work on this.

6f8c63fbd7 spice: connection events.
This patch adds support for connection events to spice.  The events are
quite simliar to the vnc events.  Unlike vnc spice uses multiple tcp
channels though.  qemu will report every single tcp connection (aka
spice channel).  If you want track spice sessions only you can filter
for the main channel (channel-type == 1).

a19cbfb346 spice: add qxl device
qxl is a paravirtual graphics card.  The qxl device is the bridge
between the guest and the spice server (aka libspice-server).  The
spice server will send the rendering commands to the spice client, which
will actually render them.

The spice server is also able to render locally, which is done in case
the guest wants read something from video memory.  Local rendering is
also used to support display over vnc and sdl.

qxl is activated using "-vga qxl".  qxl supports multihead, additional
cards can be added via '-device qxl".

[ v2: add copyright to files                     ]
[ v2: use qemu-common.h for standard includes    ]
[ v2: create separate qxl-vga device for primary ]

3e31375378 spice: add audio
Add support for the spice audio interface.  With this patch applied
audio can be forwarded over the network from/to the spice client.  Both
recording and playback is supported.

The driver is first in the driver list, but the can_be_default flag is
set only in case spice is active.  So if you have the spice protocol
enabled the spice audio driver is the default one, otherwise whatever
comes first after spice in the list.  Overriding the default using
QEMU_AUDIO_DRV works in any case.

[ v2: audio codestyle: add spaces before open parenthesis ]
[ v2: add const to silence array ]
