freebsd_network: Remove unneeded functions from if_var.h.

FreeBSD puts these in ifq.h (which we do not have), and no driver we
have actually uses them.

We can re-add the newer versions of them if we ever import a driver
which does.

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: Add new APIs used by FreeBSD 13 drivers.

freebsd_network: Reorder if_var.h slightly.

Some of the functions moved lower in this commit use functions
that were previously defined below them, which was a warning in
GCC but an error in Clang.

freebsd_network: Changes for FreeBSD 12 net80211.

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.

Sync atheros813x with FreeBSD

Signed-off-by: Adrien Destugues <pulkomandy@pulkomandy.tk>

Fixes #12328.
Fixed a style error (2 lines between functions).

Use a rw_lock instead of a mutex.

This however doesn't seem to improve performance here.
Need to investigate lock contention I think.

merged changes from 8.2 FreeBSD release for most wlan drivers and net80211.
updated several firmwares for iprowifi4965 and iprowifi3945. Tested on iprowifi4965 only.

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

Added new methods introduced in freebsd head that encapsulate macros to allow better binary compatibility if the locking way ever changes. These are not really useful, but needed for newer drivers sourcecode.

Completely renovated the FreeBSD compatibility layer:
* Removed NETDEV() and DEVNET() macros and functionality.
* The exported devices are now attached to ifnet objects only, therefore, the
ifnet object now has the receive queue, and everything else a device could
need.
* There is now a root device where everything else is attached, it currently
only holds the pci_info structure, so it's more or less a PCI child.
* This simplified the device handling a bit everywhere.
* We now attach drivers already in init_driver() - this is needed as drivers
may publish more than one interface when being attached.
* Implemented device_delete_child(), device_attach() (which bus_generic_attach()
now uses), device_is_attached(), and device_is_alive().
* Therefore, if_initname() does now the actual job of registering the devices.
* On open, if_init() is called which comes pretty close to what our open()
is supposed to do.
* Updated ukphy.c to the one from FreeBSD 7 where used (we should probably
move that into the compat layer, anyway).
* The MII driver array must now be NULL terminated; therefore you don't need
to specify the count anymore.
* Moved PCI code from compat.c to bus.c.
* Moved the driver code from device.c to driver.c.
* Removed superfluous init_compat_layer() function.
* Fixed a few bugs, a few things weren't brought down correctly.
* The rtl8139 interrupt routine now checks if it really was the cause of the
interrupt - this code is not tested, either, it may not work (which would
then require a work-around like I did for the 3com driver).
* The HAIKU_PROTECT_INTR_REGISTER in the rtl8139 driver was pretty much useless
which is why I removed it.
* Probably introduced a lot of new bugs, though - I haven't tested this code
at all yet. It will probably just crash :-)
