Actually, I'm turning this function into a macro as filename,
function name and line number needs to be passed. The new
function virAsprintfInternal is introduced with the extended set
of arguments.

Similarly to VIR_STRDUP, we want the OOM error to be reported in
VIR_ALLOC and friends.

Initially proposed as [1], but then changed to comment fix only.  VMDK
can have internal version set to 2 when there are few features added
which do not affect us.  Thanks to Jan's commit a1ee8e18 this can be
easily fixed by adding it to list of supported versions.

This helper function is used to create parent directory for
the hostdev which will be added to the container. If the
parent directory of this hostdev doesn't exist, the mknod of
the hostdev will fail. eg with /dev/net/tun

Many applications use /dev/tty to read from stdin.
e.g. zypper on openSUSE.

Let's create this device node to unbreak those applications.
As /dev/tty is a synonym for the current controlling terminal
it cannot harm the host or any other containers.
