Peter Krempa 663b1d55de qemu: hotplug: consolidate media change code paths
Use qemuDomainAttachDeviceDiskLive to change the media in
qemuDomainChangeDiskLive as the former function already does all the
necessary steps to prepare the new medium.

This also allows us to turn qemuDomainChangeEjectableMedia static.

Ján Tomko 9cf38263d0 Switch from yajl to Jansson
Yajl has not seen much activity upstream recently.
Switch to using Jansson >= 2.5.

All the platforms we target on https://libvirt.org/platforms.html
have a version >= 2.7 listed on the sites below:
https://repology.org/metapackage/jansson/versions
https://build.opensuse.org/package/show/devel:libraries:c_c++/libjansson

Additionally, Ubuntu 14.04 on Travis-CI has 2.5. Set the requirement
to 2.5 since we don't use anything from newer versions.

Implement virJSONValue{From,To}String using Jansson, delete the yajl
code (and the related virJSONParser structure) and report an error
if someone explicitly specifies --with-yajl.

Also adjust the test data to account for Jansson's different whitespace
usage for empty arrays and tune up the specfile to keep 'make rpm'
working when bisecting.

Michal Privoznik 5c81c342a7 qemu_hotplug: Allow asynchronous detach
The virDomainDetachDeviceAlias API is designed so that it only
sends detach request to qemu. It's user's responsibility to wait
for DEVICE_DELETED event, not libvirt's. Add @async flag to
qemuDomainDetach*Device() functions so that caller can chose if
detach is semi-synchronous (old virDomainDetachDeviceFlags()) or
fully asynchronous (new virDomainDetachDeviceFlags()).

Shalini Chellathurai Saroja f245a9791c qemu: introduce capability for virtual-css-bridge
Let us introduce the capability QEMU_CAPS_CCW for virtual-css-bridge
and replace QEMU_CAPS_VIRTIO_CCW with QEMU_CAPS_CCW in code segments
which identify support for ccw devices.

The virtual-css-bridge is part of the ccw support introduced in QEMU 2.7.
The QEMU_CAPS_CCW capability is based on the existence of the QEMU type.

Let us also add the capability QEMU_CAPS_CCW to the tests which
require support for ccw devices.

Laine Stump 9b0848d523 qemu: propagate virQEMUDriver object to qemuDomainDeviceCalculatePCIConnectFlags
If libvirtd is running unprivileged, it can open a device's PCI config
data in sysfs, but can only read the first 64 bytes. But as part of
determining whether a device is Express or legacy PCI,
qemuDomainDeviceCalculatePCIConnectFlags() will be updated in a future
patch to call virPCIDeviceIsPCIExpress(), which tries to read beyond
the first 64 bytes of the PCI config data and fails with an error log
if the read is unsuccessful.

In order to avoid creating a parallel "quiet" version of
virPCIDeviceIsPCIExpress(), this patch passes a virQEMUDriverPtr down
through all the call chains that initialize the
qemuDomainFillDevicePCIConnectFlagsIterData, and saves the driver
pointer with the rest of the iterdata so that it can be used by
qemuDomainDeviceCalculatePCIConnectFlags(). This pointer isn't used
yet, but will be used in an upcoming patch (that detects Express vs
legacy PCI for VFIO assigned devices) to examine driver->privileged.

John Ferlan 8550e8585e qemu: Add secret object hotplug for TCP chardev TLS
https://bugzilla.redhat.com/show_bug.cgi?id=1300776

Complete the implementation of support for TLS encryption on
chardev TCP transports by adding the hotplug ability of a secret
to generate the passwordid for the TLS object for chrdev, RNG,
and redirdev.

Fix up the order of object removal on failure to be the inverse
of the attempted attach (for redirdev, chr, rng) - for each the
tls object was being removed before the chardev backend.

Likewise, add the ability to hot unplug that secret object as well
and be sure the order of unplug matches that inverse order of plug.
