Make room for media types of the future. Extend the ifmedia word to 64 bits.
This changes numbers of the SIOCSIFMEDIA and SIOCGIFMEDIA ioctls and
grows struct ifmediareq.

Old ifconfig and dhclient binaries can still assign addresses, however
the 'media' subcommand stops working. Recompiling ifconfig and dhclient
with new headers before a reboot should not be necessary unless in very
special circumstances where non-default media settings must be used to
get link and console access is not available.

There may be some MD fallout but that will be cleared up later.

Get rid of devact enum, substitute it with an int and coresponding defines.

Never return nonzero in a device activate method invoked with DVACT_ACTIVATE,

comment fix from Brad; OpenBSD's mii_phy_add_media() does not print
the media names like NetBSD does.

First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

Since Ethernet links can only be full duplex or half duplex the link
state reporting code in the MII layer / em(4) and vge(4) will never
fall back to the point of only reporting the link as being UP without
the duplex setting being reported, so simplify the code a bit here.

state, if known by the driver. this is required to check the full
duplex state without depending on the ifmedia ioctl which can't be
called in the kernel without process context.

Make carp(4) aware of its physical interface:

the carp interface goes down as well.
- We treat this like the preemption holdoff with pfsync.
So if one of the carp interfaces is known to be bad (because the
physical interface it's associated with is bad), all the other carp
interfaces back off: they won't preempt, and their advskew goes to 240.
