Merge remote-tracking branch 'origin/master' into dev/netservices

freebsd_network: Move up Giant ownership during attach.

device_attach can be recursed for MIIbus drivers, so avoid the complexity
and lock Giant from init_drivers() instead.

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.)

freebsd_network: Add child drivers directly rather than finding symbols.

This method is much less error-prone than the prior one, as that required
the driver structure to have an exported symbol identical to its "name"
field, a fact that is usually true but not always (we've had an ifdef
in the atheroswifi driver for a while now due to this.)

So when we have it, we now just use the driver_t* directly, which
should push any of these problems from the run-time stage to the
compile-time stage. It's also a significant performance
improvement.

freebsd_network: Reinstate _fbsd_init_hardware and refactor probing.

Previously we just probed and then immediately attached if any devices
were found, after all initialization was done. Now we cannot do that,
as after calling SYSINIT() on certain drivers (e.g. the new ipro1000
driver), certain threads will be created that there is no good way
of tearing down.

Fortunately, it is valid to call probe() on a device before SYSINIT()
(and most other things) have been initialized, and so now we do that
in init_hardware, and then init_driver is called only if we've found
devices we support.

While we're at it, also call pci->reserve_device, which will mark us as
the driver handling said device and prevent other drivers from
using it.

freebsd_network: Implement SYSINIT.

Based on the already-existing linkersets framework, which seems to
work pretty well for the atheroswifi driver, so it should work for
this case also.

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.

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.
