To enable translation management systems to add new languages they need
to be able to modify the supported language list. The LINGUAS file is a
simple standard format that can be used for the language list, as this
is easier than modifying make variables.

Long ago we switched the vbox driver to run inside libvirtd to avoid
libvirt.so being polluted with GPLv2-only code. Since libvirtd is not
built on Windows, we disabled vbox on Windows builds. Thus the MSCOM
glue code is not required.

The virbpf module wraps syscalls to BPF. However, if the kernel
headers used at the compile time don't have support for BPF the
module offers stubs which return a negative one to signal error
to the caller. But there is a slight discrepancy between real
functions and these stubs. While the former set errno and return
-1 the latter report an error (without setting the errno) and
return -1. This is not optimal because the caller might see stale
errno and overwrite the error message with a less accurate one.

lxcDomainMergeBlkioDevice() and qemuDomainMergeBlkioDevice()
are the same functions. This duplicated code can't be put in
the existing domain_cgroup.c since it's not cgroup related.

This patch introduces a new src/hypervisor/domain_driver.c to
host this more generic code that can be shared between virt
drivers. This new file is then used to create a new helper
called virDomainDeivceMergeBlkioDevice() to eliminate the code
repetition mentioned above. Callers in LXC and QEMU files
were updated.

This change is a preliminary step for more code reduction of
cgroup related code inside lxcDomainSetBlkioParameters() and
qemuDomainSetBlkioParameters().

When building RPMs for libvirt the PO files are part of libvirt-libs
package.  Now that we generate libvirt.pot during build time the POT
creation date is also generated at that time.

The issue here is that when building libvirt-libs for x86_64 and i686
the generated libvirt.pot file will have different POT creation date
which affects installed PO files as well which leads to conflict when
installing both x86_64 and i686 packages.

This function loads the BPF prog with prepared map into kernel and
attaches it into guest cgroup.  It can be also used to replace existing
program in the cgroup if we need to resize BPF map to store more rules
for devices. The old program will be closed and removed from kernel.

There are two possible ways how to create BPF program:

    - One way is to write simple C-like code which can by compiled into
      BPF object file which can be loaded into kernel using elfutils.

    - The second way is to define macros which look like assembler
      instructions and can be used directly to create BPF program that
      can be directly loaded into kernel.

Since the program is not too complex we can use the second option.

If there is no program, all devices are allowed, if there is some
program it is executed and based on the exit status the access is
denied for 0 and allowed for 1.

Our program will follow these rules:

    - first it will try to look for the specific key using major and
      minor to see if there is any rule for that specific device

    - if there is no specific rule it will try to look for any rule that
      matches only major of the device

    - if there is no match with major it will try the same but with
      minor of the device

    - as the last attempt it will try to look for rule for all devices
      and if there is no match it will return 0 to deny that access
