78b9b85c06 log: daemon: Add remote protocol handling for the log appending API 
Implement the RPC dispatcher and caller for the new API.

5e6143fbcc log: handler: Add new API to append to logging files 
For logging one-shot entries to the VM log file it's quite a waste to
hold open the file descriptor for logging that is provided by the
current API.

This new API will be ideal for logging one-shot entries to the file
e.g. at the point when we shut the VM down rather than having to add the
whole file-descriptor infrastructure.

Additionally this will allow to add the messages even after restart of
libvirtd since virtlogd doesn't allow to obtain a regular context with
filedescriptors while the VM is still active.

Document the return value of virRandomBytes as 0 or some errno value and
then make sure all callers make the proper checks.

577fb98fbd qemu: process: Allow VIR_QEMU_PROCESS_START_NEW in qemuProcessLaunch 
The new flag was not added to virCheckFlags in commit '0d1c17aa' causing
a regression where VMs were not able to start.

18f1dda390 conf: Move validation of disk LUN device to the appropriate place 
Now with the proper domain config validation infrastructure the check
can be moved to a place that doesn't make domains vanish.

05eab1bf9a conf: Move disk info validator to the domain conf validator 
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.

d071d292ca qemu: process: Call the domain config validator when starting a new VM

0d1c17aa68 qemu: process: Convert multiple boolean args to a single flag 
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.

9890a7a183 conf: Add device def validation callback 
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.

b394af162a conf: Add infrastructure for adding configuration validation 
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.

e545806db9 Only return two values in udevGetStringSysfsAttr

71402ef6f5 Only return two values in udevGetStringProperty 
There is no need to differentiate between PROPERTY_FOUND
and PROPERTY_MISSING - we can just look if the string is non-NULL.

4ccf6886c8 Fix the return value in udevKludgeStorageType 
Since the switch to VIR_STRDUP this function returns 1 on success,
but the caller treats any non-zero value as failure.

df7291c31c udevProcessFloppy; remove unnecessary allocation 
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.

0d372687eb Do not VIR_STRDUP the string in udevGetDeviceProperty

Also change the comment at the beginning of the function, because

1a97fb16ae Remove udevStrToLong_ull 
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.
