344582a8a7 bhyve: fix virObjectUnlock() usage
In a number of places in the bhyve driver, virObjectUnlock()
is called with an arg without check if the arg is non-NULL, which
could result in passing NULL value and a warning like:

virObjectUnlock:340 : Object 0x0 ((unknown)) is not a virObjectLockable instance

* src/bhyve/bhyve_driver.c (bhyveDomainGetInfo)
(bhyveDomainGetState, bhyveDomainGetAutostart)
(bhyveDomainSetAutostart, bhyveDomainIsActive)
(bhyveDomainIsPersistent, bhyveDomainGetXMLDesc)
(bhyveDomainUndefine, bhyveDomainLookupByUUID)
(bhyveDomainLookupByName, bhyveDomainLookupByID)
(bhyveDomainCreateWithFlags, bhyveDomainOpenConsole):
Check if arg is not NULL before calling virObjectUnlock on it.

23419a62c2 bhyveConnectGetCapabilities: Fix double caps unref
At the beginning of the function we gain a reference to the driver
capabilities. Then, we call format function (*) which if failed, unref
over caps is called. Then, at the end another unref occurs.

* - Moreover, the format was not called over gained caps, but over
privconn->caps directly which is not allowed anymore.

6c91134de4 bhyve: add console support through nmdm device
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.

1d8be34334 bhyve: don't leak tap devices on failures
On failures, virBhyveProcessStart() does not cleanup network
interfaces that could be created by virBhyveProcessBuildBhyveCmd(),
which results in a leaked tap device.

To fix that, extract network cleanup code to bhyveNetCleanup()
and use it in cleanup stage of virBhyveProcessStart().

b9dd878ff8 util: make it easier to grab only regular command exit
Auditing all callers of virCommandRun and virCommandWait that
passed a non-NULL pointer for exit status turned up some
interesting observations.  Many callers were merely passing
a pointer to avoid the overall command dying, but without
caring what the exit status was - but these callers would
be better off treating a child death by signal as an abnormal
exit.  Other callers were actually acting on the status, but
not all of them remembered to filter by WIFEXITED and convert
with WEXITSTATUS; depending on the platform, this can result
in a status being reported as 256 times too big.  And among
those that correctly parse the output, it gets rather verbose.
Finally, there were the callers that explicitly checked that
the status was 0, and gave their own message, but with fewer
details than what virCommand gives for free.

So the best idea is to move the complexity out of callers and
into virCommand - by default, we return the actual exit status
already cleaned through WEXITSTATUS and treat signals as a
failed command; but the few callers that care can ask for raw
status and act on it themselves.
