bhyveBuildNetArgStr() calls virNetDevTapCreateInBridgePort() and
passes tapfd = NULL, but tapfdSize = 1. That is wrong, because
if virNetDevTapCreateInBridgePort() crashes after successfully
creating a TAP device, it'll jump to 'error' label, that
loops over tapfd and calls VIR_FORCE_CLOSE:
for (i = 0; i < tapfdSize && tapfd[i] >= 0; i++)
In that case we get a segfault.
As the bhyve code doesn't use tapfd, pass NULL and set tapfdSize to 0.
Automatically allocate PCI addresses for devices instead
of hardcoding them in the driver code. The current
allocation schema is to dedicate an entire slot for each devices.
Also, allow having arbitrary number of devices.
nmdm is a FreeBSD driver which allows to create a pair of tty
devices one of which is passed to the guest and second is used
by the client.
This patch adds new 'nmdm' character device type. Its definition
looks this way:
<serial type='nmdm'>
<source master='/dev/nmdm0A' slave='/dev/nmdm0B'/>
</serial>
Master is passed to the hypervisior and slave is used for client
connection.
Also implement domainOpenConsole() for bhyve driver based on that.
To ease mocking for bhyve unit tests move virBhyveTapGetRealDeviceName()
out of bhyve_command.c to virnetdevtap and rename it to
virNetDevTapGetRealDeviceName().
We use virBhyveTapGetRealDeviceName() to map network interface name
to a real device path, trying to open possible devices and getting
names by ioctl.
Make it skip devices that fail to open with EBUSY because they're
most likely already used by other VMs.
Part of a series of cleanups to use new accessor methods.

Any source file which calls the logging APIs now needs
to have a VIR_LOG_INIT("source.name") declaration at
the start of the file. This provides a static variable
of the virLogSource type.

Addition of the hostbridge device was mistakenly placed to
bhyveBuildNetArgStr(). This could result in hostbridge device not being
added to the commandline if there are no network devices specified, but
hostbridge device should be added unconditionally.
Fix by placing it to virBhyveProcessBuildBhyveCmd().
At this point it has a limited functionality and is highly
experimental. Supported domain operations are:
* define
* start
* destroy
* dumpxml
* dominfo
It's only possible to have only one disk device and only one
network, which should be of type bridge.
