Use issuer type instead of event type to group
vm related events. This saves us from
explicit enumeration of all vm event types in
prlsdkHandleVmEvent.

Not every architecture out there has 'char' signed by default.
For instance, my arm box has it unsigned by default:

  $ gcc -dM -E - < /dev/null | grep __CHAR_UNSIGNED__
  #define __CHAR_UNSIGNED__ 1

Therefore, after 65c61e50 the test if failing for me. Problem is,
we are trying to assign couple of negative values into char
assuming some will overflow and some don't. That can't be the
case if 'char' is unsigned by default. Lets use more explicit types
instead: int8_t and uint8_t where is no ambiguity.

Commit 825df8c3 refactored virProcess{Set,Get}Affinity routines,
however broke BSD implementation because of the incorrect variable
name. Fix build by using a proper variable name.

Pushing as trivial and build break fix.

The stubs for the two functions that are compiled on platforms that
don't have HAVE_GETPWUID_R and friends defined do not return error but
report an error message. The calling code then assumes that the @uid or
@gid arguments were filled, which is not the case in the stubs.

We were effectively ignoring its errors anyway.

The monitor code does not hold the virDomainObjPtr lock and should
not access the defitinion.

There's no point in calling the monitor if there is no balloon.

There is nothing to get from the monitor for model='none'.

It only makes sense if qemuMonitorGetMemoryStats is called,
but the following patch will make that call conditional.

Reduce the indentation level.

All the callers use "/" anyway.

When traversing through the QOM tree, we're looking for
a link to a device, e.g.:
link<virtio-balloon-pci>

Introduce a helper that will format the link name at the start,
instead of doing it every time while recursing through the tree.

This function is specific to the JSON monitor.

Ref service passed as a parameter to the callback.  And don't unref the
socket that is part of the service being passed at another point in code.

When building without avahi support, we used VIR_DEBUG() to note that to
the user.  However, functions that fail because of that (return NULL/-1)
did not set the error message.  This was the only file that forgot to do
such thing.

The virStorageBackendFileSystemIsMounted is called from three source paths
checkPool, startPool, and stopPool. Both start and stop validate the FS
fields before calling *IsMounted; however the check path there is no call.
This could lead the code into returning a true in "isActive" if for some
reason the target path for the pool was mounted. The assumption being
that if it was mounted, then we believe we started/mounted it.

It's also of note that commit id '81165294' added an error message for
the start/mount path regarding that the target is already mounted so
fail the start. That check was adjusted by commit id '13fde7ce' to
only message if actually mounted.

At one time this led to the libvirtd restart autostart code to declare
that the pool was active even though the startPool would inhibit startup
and the stopPool would inhibit shutdown. The autostart path changed as
of commit id '2a31c5f0' as part of the keep storage pools started between
libvirtd restarts.

This patch adds the same check made prior to start/mount and stop/unmount
to ensure we have a valid configuration before attempting to see if the
target is already mounted to declare "isActive" or not. Finding an improper
configuration will now cause an error at checkPool, which should make it
so we can no longer be left in a situation where the pool was started and
we have no way to stop it.

Currently the assumption on the error message is that there are
no source device paths defined when the number of devices check
fails, but in reality the XML could have had none or it could have
had more than the value supported. Adjust the error message accordingly
to make it clearer what the error really is.

Refactor the code for both startPool (*Mount) and stopPool (*Unmount) code
paths by introducing virStorageBackendFileSystemIsValid.

Over time the parameters changed, but the comment wasn't updated

Commit 1882c0bd accidentally used ',' instead of ';'; oddly
enough, the result was still syntactically valid (yes, C is
a fun language).  But it made me do a double take; it's better
to use idiomatic syntax.

In qemuDomainUpdateCurrentMemorySize I misplaced the actual update of
the balloon size to a place where it may not be initialized. Move it a
few lines above.

Coverity rightfully determined that in commit 3d021381
I made a mistake in the first check if @persDef is not NULL is
dereferencing it rather than checking.

Additionally if the vm is online the code would set @liveDef twice
rather than modifying @persDef. Fix both mistakes.

When getting block device I/O tuning data there is no check for whether
QEMU supports such options and the call fails on
qemuMonitorGetBlockIoThrottle() when getting the particular throttle
data.  So try reporting a better error when blkdeviotune is not
supported.

virDomainLiveConfigHelperMethod that is used for this job now does
modify the flags but still requires the callers to extract the correct
definition objects.

In addition coverity and other static analyzers are usually unhappy as
they don't grasp the fact that @flags are upadted according to the
correct def to be present.

To work this issue around and simplify the calling chain let's add a new
helper that will work only on drivers that always copy the persistent
def to a transient at start of a vm. This will allow to drop a few
arguments. The new function syntax will also fill two definition
pointers rather than modifying the @flags parameter.

The vCPU pinning definition gets removed when the domain definition is
being freed later. If there is no next configuration it would remove the
configured pinning.
