Now that we can include <interface type='ethernet'> in tests, we could
almost test XML that has an <ip> element in an interface. Except that
the test fails when it tries to actually set the IP address for the
interface's tap device. This patch mocks virNetDevSetIPAddress() to
just return success.

Rearrange this function to be better organized and more correct:

* the error codes were changed from the incorrect INVALID_ARG to
  XML_ERROR

* prefix still isn't required, but if present it must be valid or an
  error will be logged.

* don't emit a debug log just because prefix is missing - this
  is valid.

* group everything related to setting prefix in one place rather than
  scattered through the function.

I'm tired of mistyping this all the time, so let's do it the same all
the time (similar to how we changed all "Pci" to "PCI" awhile back).

(NB: I've left alone some things in the esx and vbox drivers because
I'm unable to compile them and they weren't obviously *not* a part of
some API. I also didn't change a couple of variables named,
e.g. "somethingIptables", because they were derived from the name of
the "iptables" command)

These had been declared in conf/device_conf.h, but then used in
util/virnetdev.c, meaning that we had to #include conf/device_conf.h
in virnetdev.c (which we have for a long time said shouldn't be done.

This caused a bigger problem when I tried to #include util/virnetdev.h
in a file in src/conf (which is allowed) - for some reason the
"device_conf.h: File not found" error.

The solution is to move the data types and functions used in util
sources from conf to util. Some names were adjusted during the move
("virInterface" --> "virNetDevIf", and "VIR_INTERFACE" -->
"VIR_NETDEV_IF")

virNetDevLinkDump should have been in virnetlink.c, but that file
didn't exist yet when the function was created. It didn't really
matter until now - I found that having virnetlink.h included by
virnetdev.h caused build problems when trying to #include virnetdev.h
in a .c file in src/conf (due to missing directory in -I). Rather than
fix that to further institutionalize the incorrect placement of this
one function, this patch moves the function.

With respect to to the following thread
https://www.redhat.com/archives/libvir-list/2016-June/msg01822.html, until we
introduce a new rpm package '-libs' that would allow us to drop daemon's
dependency on the client package, distribute admin API related stuff within
the client package (since it's the best analogy to the virsh client).

Some of the examples make use of asprintf and strtol functions (to keep
things simple) which are prohibited to use within our code (enforced by
syntax-check). Therefore besides adding some examples, this patch also updates
cfg.mk to exclude examples directory from asprintf and strtol rules, as well as
updates .gitignore to exclude all the new admin binaries created in the
'examples' dir.

This patch enables admin socket creation in daemon's code, bumps the library
version in libvirt_admin_public.syms, and performs all necessary modifications
to our makefiles so that admin API can finally be included in the tarball,
and eventually become part of an rpm package (a patch later in this series).

First we need to always set value to vz sdk parameter so
we can leverage setting code for device updates. This patch
resolves tristate default to off implicitly. This is easier
then extract default value from vz sdk itself. First current
default is off too, second this approach is already taken
for 'net->linkstate'.

Second dump this option in domain xml.

Current code that pass gateways to vz sdk is not suitable for
updates. If update has no gateways while we had them before
we need to pass "" for vz sdk gateways to reset old value.

The code definitely deserves its own function.

Drop checks that skip setting gateways if network address
is not set. Such a configuration is possible in vz sdk.
