This file was modified in an editor buffer but not saved prior to
commit e62cb4a9 (which removed virMacAddr::generated), so the bhyve
build would fail.

It will come handy to know if the MAC address was generated (e.g.
during XML parse) or if it was parsed since provided by user in
the XML.

This patch makes use of the virNetDevSetCoalesce() function to make
appropriate settings effective for devices that support them.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1414627Signed-off-by: NMartin Kletzander <mkletzan@redhat.com>

virNetDevTapCreateInBridgePort() has always set the new tap device to
the current MTU of the bridge it's being attached to. There is one
case where we will want to set the new tap device to a different
(usually larger) MTU - if that's done with the very first device added
to the bridge, the bridge's MTU will be set to the device's MTU. This
patch allows for that possibility by adding "int mtu" to the arg list
for virNetDevTapCreateInBridgePort(), but all callers are sending -1,
so it doesn't yet have any effect.

Since the requested MTU isn't necessarily what is used in the end (for
example, if there is no MTU requested, the tap device will be set to
the current MTU of the bridge), and the hypervisor may want to know
the actual MTU used, we also return the actual MTU to the caller (if
actualMTU is non-NULL).

 * virNetDevTapCreateInBridgePort() mock: free '*ifname' before
   strdupping a hardoded value to it
 * testCompareXMLToArgvFiles(): unref 'conn' object in cleanup
 * testCompareXMLToArgvHelper(): free 'ldargs' and 'dmargs' in
   cleanup

Commit c5b6a4a5 forget to update also this mock function.

Commit b20d39a5 introduced a new argument for the
virNetDevTapCreateInBridgePort function, however, its mock
in bhyve tests wasn't updated, so the build failed.

Fix build by adding this new argument to the mock version.

At this point unittest covers 4 basic cases:

 - minimal working XML for bhyve
 - same as above, but with virtio disk
 - ACPI and APIC args test
 - MAC address test
