Since it will not be called from outside of conf we can unexport it too
if we move it to the appropriate place.
Test suite change is necessary since the error will be reported sooner
now.
Validation of qemu process startup requires to know whether the process
is used for a fresh VM or whether it's reloaded from a
snapshot/migration. Pass this information in via a flag rather than
calculating it from a bunch of bools.
Similarly to the domain definition validator add a device validator. The
change to the prototype of the domain validator is necessary as
virDomainDeviceInfoIterateInternal requires a non-const pointer.
Until now we weren't able to add checks that would reject configuration
once accepted by the parser. This patch adds a new callback and
infrastructure to add such checks. In this patch all the places where
rejecting a now-invalid configuration wouldn't be a good idea are marked
with a new parser flag.
Historically, we added heads=1 to videos, but for example for qxl, we
did not reflect that on the command line.

Use udevHasDeviceProperty instead of udevGetStringProperty.
We do not need to copy the string since we do not need it.
Also add braces around the if body, since the change made
syntax check complain.
Two out of three callers free it right after converting it to a number.
Also change the comment at the beginning of the function, because
the comment inside the function told me to.
The wrapper adds an error message or a debug log.
Since we already log the properties we get from udev as strings,
there is no much use for the debug logs.
Open code the error message and delete the function.
Most of the code paths had to reset it to -1 and returning 0 was
only possible if we made it to the end of the function.
Initialize it to -1 and only set it to 0 if we reach the end, as we do
in most of libvirt code.
The sd_notify method is used to tell systemd when libvirtd
has finished starting up. All it does is send a datagram
containing the string parameter to systemd on a UNIX socket
named in the NOTIFY_SOCKET environment variable. Rather than
pulling in the systemd libraries for this, just code the
notification directly in libvirt as this is a stable ABI
from systemd's POV which explicitly allows independant
implementations:
See "Reimplementable Independently" column in the
"$NOTIFY_SOCKET Daemon Notifications" row:

Move the module from qemu_command.c to a new module virqemu.c and
rename the API to virQEMUBuildObjectCommandline.
This API will then be shareable with qemu-img and the need to build
a security object for luks support.

Split out a helper from virStorageBackendCreateQemuImgCmdFromVol
to check the encryption - soon a new encryption sheriff will be
patroling and that'll mean all sorts of new checks.

I was asked the other day what's event loop and how libvirt uses
it. Well, I haven't found any good sources on the Internet so I
thought of writing the documentation on my own.

Remove the live attribute and mark the definition as transient
whether the domain is runing or not.
There were only two callers left calling with live=false:
* testDomainStartState, where the domain already is active
because we assigned vm->def->id just a few lines above the call
* virDomainObjGetPersistentDef, which now only calls
virDomainObjSetDefTransient for an active domain
Calling virDomainObjSetDefTransient with live=false is a no-op
on an inactive domain.
Only call it on an active domain, since this is the only place using
the live bool.
