freebsd_network: Adjust and rewrite attach code for USB support.

init_hardware now takes 2 devices arrays: one for PCI and one for USB
drivers, respectively.

The few drivers that have their own __haiku_handle_fbsd_drivers_list
are also adjusted at the same time.

freebsd_network: Introduce USB-handling code.

It is not yet wired in to the rest of the compatibilit layer;
that will happen in the next commits.

The bulk of the implementation is in usb.cpp; most of the
rest of the new files are copied from FreeBSD to varying degrees.

freebsd_network: PCI handling cleanup in preparation for USB support.

Should not have any functional change.

freebsd_network: Completely overhaul bus_dma implementation.

The old implementation was based on an ancient copy of the FreeBSD
busdma code for x86, and did not make a bunch of assumptions that
we make basically everywhere else (for instance, that we can request
arbitrarily-aligned contiguous physical memory from the VM.)

As a consequence, it had a significant amount of code devoted to
bounce pages, which are just a waste of resources on x86, and
for that matter, probably any other architecture Haiku will ever
be ported to. (Even if we do need to run on some system where
only a small portion of system memory can be accessed by devices,
likely we would reserve that memory for just this occasion anyway.)

I was initially under the impression that the bounce-pages code
never turned on, but apparently due to the "alignment" check
(and also the "Maxmem" check, which was to defined to 32KB...?!)
it does indeed activate on a variety of systems, and maybe
(in the case of drivers that do not call sync() properly) even
is the cause of some of our ported driver breakage.

The new implementation is pretty much optimized for Haiku,
and shares almost no code or structure with the old one (save
for a few functions that really only have one proper implementation.)

Tested with ipro1000 and rtl81xx. Regressions are more than possible,
so please don't hesitate to file bugs if your network driver now
fails to come up (or you get KDLs.)

Prevent a double softc free.

- Keep track if the softc was allocated externally or not.
- Only try to deallocate it if it was allocated internally.

Do not try to free the softc if we were not the ones allocating it.

- Avoid a double free on consecutive calls to device_set_softc.

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.

FreeBSD compat layer: implement MSI-X support.

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.

Implement MSI support using the x86 specific PCI module in the FreeBSD
compatibility layer. This should make some network and wireless hardware use
MSIs and therefore solve issues related to interrupt sharing and wrongly
advertised interrupt lines.

* Copyright style fixes.

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.

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 :-)
