freebsd_network & drivers: Remove need to specify FBSD_TASKQUEUES.

Instead make FBSD_TASKQUEUES a combination flag of all taskqueues,
so that if even one is needed, the init_taskqueues function will
be invoked appropriately.

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: 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.

Drop requirement for specifying firmware map size

The HAIKU_FIRMWARE_NAME_MAP macro takes a size parameter to define the
firmware map array type, and then a multi-dimensional array literal is
assigned to the array defined by that macro.

This is error-prone. The idualwifi7260 driver, before this patch, had
the size incorrectly set to 6 when the number of entries was 7, which
sliced the last entry off of the map, making it unavailable to the
driver. After fixing this size, the driver properly loads the
iwm-8265-22.ucode firmware on my computer.

This patch changes that macro to take a const char[][2] literal as its
only parameter, making it less likely for this sort of bug to be
re-introduced.

Fixes #15413.

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: Add an "id" field to struct device_method.

"const char* name" is alright for the compat layer's needs to
identify functions, as we only scan the method table once and
copy the function pointers to a struct of function pointers.

iflib doesn't use a function pointer struct, though, and expects
to have the KOBJ system for function lookups, and that depends
on integer-based method IDs for fast lookups. So now every
method gets an integer ID as well as a name (and iflib's method
IDs are in the list of method IDs already.)

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.

Update FreeBSD network drivers with the 9.1 release

* FreeBSD compatibility layer for network drivers is modified to handle
NULL-terminated list of driver_t* entries instead of single entry.
That allows to combine multiple FreeBSD drivers into single Haiku
driver add-ons;
* Support for DEC 21140 (Tulip) chipsets (provided by the 'de' driver)
incorporated into dec21xxx driver. That brings network connectivity to
Haiku systems running in MS Virtual PC VMs.

e1000 driver.

* Reworked firmware loading. This gets rid of the need for the settings files.
Name mapping is now defined in the glue code.
* Adding two macros for handling firmware name mapping completely in the glue
code:
- HAIKU_FIRMWARE_NAME_MAP(firmwarePartsCount) is used when mapping is
required. Have a look to iprowifi2100's glue code for an example.
- NO_HAIKU_FIRMWARE_NAME_MAP() is used when the firmware names don't need to
be mapped. For example: broadcom43xx
* Discard usage of vm_map_file() and use the previously read() method again.
After Axel and Ingo agree that both methods are fine in this particular use
case, using read() looks easier on the eye. It needs only 3 parameters, where
vm_map_file() takes 10.

* Removed old mutex implementation and renamed cutex to mutex.
* Trivial adjustments of code using mutexes. Mostly removing the
mutex_init() return value check.
* Added mutex_lock_threads_locked(), which is called with the threads
spinlock being held. The spinlock is released while waiting, of
course. This function is useful in cases where the existence of the
mutex object is ensured by holding the threads spinlock.
* Changed the two instances in the VFS code where an IO context of
another team needs to be locked to use mutex_lock_threads_locked().
Before it required a semaphore-based mutex implementation.

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 :-)
