Introduce support for codec type 'output' ('hda-output' in QEMU) for ich6
and ich9 sound devices, which only advertises a line-out in the guest.
This has been available in QEMU since 0.14.

Unfortunately, when there are none, qemuBuildNumaArgStr() is not

too.

QEMU has this new feature memory-backend-file.discard-data=yes
which is a nifty optimization. Basically, when qemu is quitting
or on memory hotplug it calls munmap() and close() on the file
that is backing the memory. However, this does not mean kernel
won't stop touching that part of memory. It still might. With
this feature enabled we tell kernel: "we don't need this memory
nor data stored in it". This makes kernel drop the memory
immediately without trying to sync memory with the mapped file.
Unfortunately, this cannot be turned on by default because we
can't be sure when users really don't care about what happens to
data after qemu dies. So it has to be opt-in. As usual, there are
three places where one can configure memory attributes. This
patch adds the feature to all of them.

For command line we need two things:
1) -object pr-manager-helper,id=$alias,path=$socketPath
2) -drive file.pr-manager=$alias
In -object pr-manager-helper we tell qemu which socket to connect
to, then in -drive file-pr-manager we just reference the object
the drive in question should use.
For managed PR helper the alias is always "pr-helper0" and socket
path "${vm->priv->libDir}/pr-helper0.sock".

The attribute can be used to disable ROM loading completely
for a device.
This might be needed because, even when the guest is configured
such that the PCI ROM will not be loaded in the PCI BAR, some
hypervisors (eg. QEMU) might still make it available to the
guest in a form (eg. fw_cfg) that some firmwares (eg. SeaBIOS)
will consume, thus not achieving the desired result.

obsolete (defaults to deny)
elevateprivileges (setuid & co, default: allow)
spawn (fork & execve, default: allow)
resourcecontrol (setaffinity, setscheduler, default: allow)
