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.

network/stack: Do not invoke SIOCGIFMEDIA but just return the already-fetched media.

This functionally disables most of the functionality of the BSD-style
SIOCGIFMEDIA, but it was never used in userland (because if it had,
it would have triggered SMAP violations in the compatibility layer.)

SIOCGIFMEDIA returns BSD-style media values, which mostly overlap
with Haiku ones but have a few differences still. These are taken care
of in the compat layer by ETHER_GET_LINK_STATE, which is where this
media value comes from, but are not by SIOCGIFMEDIA which just passes
back whatever the drivers do.

Fixes #17770, at least for ethernet drivers.

network/stack: assume zero length ioctl requests are valid

posix ioctl calls don't provide a request length. Theorically these length checks
could be removed altogether.

network stack: added missing put_device_interface().

* Part of #7040, thanks diver!

* Fix binding to link level sockets. The bound type was constructed using the
sdl_e_type in network byte order, causing such a socket not to receive
anything.
When working around that by not using htons() on bind, sending would then fail
on such a socket because the byte order is actually required to be swapped
there.
* Extend the comment for the B_NET_FRAME_TYPE macro to document that the input
types are supposed to be in host byte order to avoid future confusion.

Prepared net_device_monitor to accept device removal events.

- Introduced public net_device_monitor.

- Adapted the link protocol to use net_device_monitor.
- Introduced a private Fifo class which doesn't maintain it's own lock.
- Maybe we should add something like a public net_protocol_implementation which maintains a fifo and a benaphore? With the fifo using the structure's lock instead of maintaining it's own.

Prepared net_device_monitor to accept device removal events.

- Introduced public net_device_monitor.
- Changed the link protocol to maintain a lock per instance instead of inside the FIFO. Now all of the link instance data is protected.
- Adapted the link protocol to use net_device_monitor.
- Introduced a private Fifo class which doesn't maintain it's own lock.
- Maybe we should add something like a public net_protocol_implementation which maintains a fifo and a benaphore? With the fifo using the structure's lock instead of maintaining it's own.

introduced fifo_socket_enqueue_buffer which clones the buffer, enqueues it to the fifo and notifies the socket.

- changed the link, ipv4 and udp modules to use fifo_socket_enqueue_buffer

properly support MSG_TRUNC. we don't even have to trim the buffer, just try to fill the user buffers as much as possible

SIOCGIFCONF will now also report the size of the written buffer in ifconf.ifc_len
to cover the case the list of interfaces changed since SIOCGIFCOUNT was called.
Patch by Hugo Santos.
