Now that we have a bit more control, let's convert our object into
a lockable object and let that magic handle the create and lock/unlock.

This commit also introduces virInterfaceObjEndAPI in order to handle the
lock unlock and object unref in one call for consumers returning a NULL
obj upon return. This removes the need for virInterfaceObj{Lock|Unlock}
external API's.

There is no "node driver" as there was before, drivers have to do
their own ACL checking anyway, so they all specify their functions and
nodeinfo is basically just extending conf/capablities.  Hence moving
the code to src/conf/ is the right way to go.

Also that way we can de-duplicate some code that is in virsysfs and/or
virhostcpu that got duplicated during the virhostcpu.c split.  And
Some cleanup is done throughout the changes, like adding the vir*
prefix etc.

There is no reason for it not to be in the utils, all global symbols
under that file already have prefix vir* and there is no reason for it
to be part of DRIVER_SOURCES because that is just a leftover from
older days (pre-driver modules era, I believe).

bhyve supports 'gop' video device that allows clients to connect
to VMs using VNC clients. This commit adds support for that to
the bhyve driver:

 - Introducr 'gop' video device type
 - Add capabilities probing for the 'fbuf' device that's
   responsible for graphics
 - Update command builder routines to let users configure
   domain's VNC via gop graphics.

Add bhyve support to virt-host-validate(1). It checks for the
essential kernel modules to be available so that user can actually
start VMs, have networking and console access.

It uses the kldnext(2)/kldstat(2) routines to retrieve modules list.
As bhyve is only available on FreeBSD and these routines were available
long before bhyve appeared, not adding any specific configure checks
for that.

Also, update tools/Makefile.am to add
virt-host-validate-$driver.[hc] to the build only if the
appropriate driver is enabled.

Create a virscsihost.c and place the functions there. That removes the
last #ifdef __linux__ from virutil.c.

Take the opporunity to also change the function names and in one case
the parameters slightly

Rather than have them mixed in with the virutil apis, create a separate
virvhba.c module and move the vHBA related calls into there. Soon there
will be more added.

Also modify the names of the functions and some arguments to be more
indicative of what is really happening. Adjust the callers respectively.

While I was changing fchosttest, rather than the non-descriptive names
test1...test6, rename them to match what the test is doing.

As bhyve for a long time didn't have a notion of the explicit SATA
controller and created a controller for each drive, the bhyve driver
in libvirt acted in a similar way and didn't care about the SATA
controllers and assigned PCI addresses to drives directly, as
the generated command will look like this anyway:

 2:0,ahci-hd,somedisk.img

This no longer makes sense because:

 1. After commit c07d1c1c it's not possible to assign
    PCI addresses to disks
 2. Bhyve now supports multiple disk drives for a controller,
    so it's going away from 1:1 controller:disk mapping, so
    the controller object starts to make more sense now

So, this patch does the following:

 - Assign PCI address to SATA controllers (previously we didn't do this)
 - Assign disk addresses instead of PCI addresses for disks. Now, when
   building a bhyve command, we take PCI address not from the disk
   itself but from its controller
 - Assign addresses at XML parsing time using the
   assignAddressesCallback. This is done mainly for being able to
   verify address allocation via xml2xml tests
 - Adjust existing bhyvexml2{xml,argv} tests to chase the new
   address allocation

This patch is largely based on work of Fabian Freyer.

Well, there were three different spots where closeCallback->freeCallback was
called, not looking the same --> potential for bugs - and there indeed is a bug
with refcounting of the @conn object. So this patch partially follows the path
set by commit 24dbb69f by introducing some close callback helpers both to
replace all the spots where we call clean the close callback data with a
dedicated function and to be able to fix the refcounting bug causing a memleak.

    - host-model is turned into custom CPU with a model and features
      copied from host
    - custom CPU with minimum match is converted similarly to host-model

First, remove escaped newlines and split up the string into an argv-list for
the bhyve and loader commands, respectively. This is done by iterating over the
string splitting it by newlines, and then re-iterating over each line,
splitting it by spaces.

Since this code reuses part of the code of qemu_parse_command.c

Unconditionally use gnulib's getopt module. This is needed by the bhyve driver
to provide a reentrant interface for getopt.

Several gnulib headers rely on features.h being included by ctype.h to provide
__GNUC_PREREQ, but on systems without glibc, this is not provided. In these
cases __GNUC_PREREQ gets redefined to 0, which causes build errors from checks
in src/internal.h.
Therefore, define __GNUC_PREREQ as early as possible. config-post.h is probably
the first header that is included, before any other headers.

Pretending (partial) support for something we don't understand is risky.
Reporting a failure is much better.
