net/if: Drop ifmediareq and just use the regular ifreq for SIOCGIFMEDIA.

This was introduced into the main API in 2010 (d72ede75fb252c24c8a5fcc39395f9ae1c202322),
but was actually only fully used for the past month (c2a9a890f3ac7795602d11c0edaa20ac2db48202)
when SIOCGIFMEDIA was supported for all *BSD drivers and not just WiFi.
Most userland consumers of this structure did not use it correctly,
as was the case in #17770, and only worked because in the fallback case
the network stack just treated it as if it were an ifreq.

Nothing actually used the ifm_count/ifm_ulist (though tentative APIs
were exposed for it) as noted by previous commits; and the fact that
Haiku's IFM_* declarations are so spartan makes most of the returned
values unintelligible to userland without using FreeBSD compat headers.

If, in the future, we decide to implement ifmedia listing and selection
properly, that should likely be done with separate ioctls instead of
having multi-function ones like this.

This is technically an ABI break, but in practice it should not matter:
ifmediareq::ifm_current aligns with ifreq::ifr_media, so the things
that used this structure like our in-tree code did will continue to work.
Until this past May, the only other field that was usually set was
ifm_active, but in the absence of setting ifm_status all non-Haiku
consumers should ignore it completely.

The only consumer of this ioctl that I know of out of the tree,
wpa_supplicant, still works after these changes.

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 compat: Updates and additions for a newer iflib.

freebsd_network: Changes for FreeBSD 12 net80211.

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.

Sync atheros813x with FreeBSD

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

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

* We now use a FreeBSD compatible ifmediareq structure for SIOCIFMEDIA, and
SIOCSIFMEDIA.
* Made sure that the two media ioctls are actually forwarded to the driver.
* Added NetworkDevice.cpp to the build.

* Added Haiku specific socket ioctls to configure the interface aliases:
SIOC_IF_ALIAS_ADD, SIOC_IF_ALIAS_REMOVE, SIOC_IF_ALIAS_GET, SIOC_ALIAS_SET,
and SIOC_IF_ALIAS_COUNT.
* Implemented all of those new ioctls, though they are yet untested.
* Added ifreq::ifr_data, and removed the hack in the FreeBSD compat if.h
header.
* Minor cleanup.

ordering.
this makes porting driver (especially wifi ones) more

* update freebsd compat with stubbed eventhandler
* get e1000 to compile
* remove dev/em from the build (might be removed later on)
* tested on VirtualBox (gcc2,gcc4), VMware(gcc4) and natively on
ThinkPad T500 (gcc4)

* Updated the FreeBSD compatibility layer for network drivers to FreeBSD 7
(RELENG_7_BP).
* There are many white spots, though, most notable PCI MSI(-X) support, and
jumbo frames.
* Fixed removing interrupts for the INTR_FAST case. Since FreeBSD 7 added
a new interrupt "filter" mechanism, we can finally report if the interface
was handled by a device or not (though only very few devices support this
yet).
* Updated the 3com, rtl8139, e1000, and via_rhine drivers to the latest code
base. They all compile, but I haven't tested them after the changes yet!
