freebsd_network: Lots of additions and modifications for iflib.

freebsd11_network -> freebsd_network.

FreeBSD 12 has no major changes to the ifnet KPIs that constitute a
source compatibility break, save a single one related to locking
which doesn't really apply to us, and so we don't need to create
a "freebsd12_network" directory to work through the upgrades.

callout_schedule uses ticks as timeunit, not usecs.

As suggested by Rene Gollent, we used ticks as usecs.

Fixed a few regressions that were introduced during the last months:
* device_attach() must not load the network stack. Besides being completely
unbalanced, this was also one reason why the stack could not be unloaded
anymore. Instead, it's now done in compat_open(), as before.
* This also fixes network booting from FreeBSD drivers - the stack apparently
could not be initialized that early.
* Replaced the previous network stack based callout implementation with one
that mostly copies its functionality, but has no dependencies. Furthermore,
it runs at a higher priority (the one of the network timer should also be
revisited, though).
* Fixed mtx_owned() to work without KDEBUG as well. It's not a good idea to
introduce code that behaves completely different based on debug settings.
* Minor cleanup.

* reordering of headerfile inclusion to comply to FreeBSD 8
ordering.
this makes porting driver (especially wifi ones) more
convinient
* based on FreeBSD svn revision 196691

* Made callout_pending() and callout_active() real functions instead of macros;
that makes drivers using it more independent from internal net_timer changes.
* Correctly implemented callout_active() using the new is_timer_running()
stack function.
