freebsd_network: Adaptations in preparation for the OpenBSD layer.

Most of these changes however add things that FreeBSD has (with a few
exceptions noted in comments) which the OpenBSD shim layer merely needs
to make use of.

(FreeBSD used to have support for IFF_NEEDSGIANT but removed it. The
support instated here is very similar to what FreeBSD used to have.)

freebsd_network: Move ticks/seconds conversions to sys/time.h and
rename.

They now match the names they have in FreeBSD.
No functional change intended.

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.

kernel drivers: have timer hooks return B_HANDLED_INTERRUPT.

* 0 means B_UNHANDLED_INTERRUPT.
* uses int32 as return type.

Include compat/sys/kernel.h rather than "kernel.h".

Using "kernel.h" was pulling in the private kernel.h header instead,
which was causing a build failure on my branch since arch_cpu.h is
C++-only there.

Tick at 1000Hz not 1MHz.

Our FreeBSD networking code defined hz to 1MHz and 1 tick = 1 / hz,
but the clock code ticked 1 tick at 1000Hz.

This caused all calculations that are done on ticks, autonegotiation
and wlan scanning to be done very often as FreeBSD uses 1000 Hz
(100Hz for ARM). Defaults for autonegotiation is 5 and 17 ticks.

(Another interesting thing is that callouts are using 8% cpu...)

Coding style fix. Thx to axeld. No functional change.

Using the add_timer() function as proposed by alexd. Thanks.

* Coding style fixes regarding whitespace usage.
* Copyright style fixes.
* Implemented FreeBSD hardclock subsystem, which is needed to update the ticks
variable. The previous usage of "#define ticks system_time()" wasn't
sufficient anymore, as there are drivers using the ticks name for local
scoped variables.

* 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
