message on input, check the unicast address before the multicast handling.

if the mac address is not for the interface, it must be multicast
or broadcast. this is instead of if the packet is not
multicast/broadcast, it must be for the interface.

this allows ethernet interfaces to have multicast mac addresses
without having to special case it themselves. eg, carp load balancing
should become easier with this.

We don't save+restore FS.base and GS.base on every context switch but
rather reset GS.base and restore FS.base to what was set via __tcb_set(),
so we can't really support the wr{fs,gs}base instructions by userspace.
Enabling CR4_FSGSBASE is therefore incorrect so stop doing so.

message pmap_map_ptes() always returns the same ptep and pdepp pointers,
so inline the assignments, pushing them through the callers into
several other functions. This shows that pmap_free_ptp() was doing
a duplicate set of pmap_tlb_shootpage() calls: delete the extras.

message Preparation for i386 Meltdown fix:

- provide a cpu_softc for cpu_attach() etc.
- replace per PCB TSS with per CPU TSS

The first change prepares for cpu_info being embedded in a
cpu_full_info. Therefore during autoconf/cpu_attach we hand down
a softc.

The second change removes the per PCB TSS. We now have one TSS per
CPU, thus in cpu_switchto() we only have to patch the ring 0 stack
pointer instead of loading a new TSS. This also allows for cleaning
up the GDT, so we only have a single slot for the TSS.

Mbuf data is used as struct ether_header before it has been made
continuous. The length of the hardware and protocol address are
provided in the network packet and have to be checked first. So
enforce that we only deal with internet over ethernet arp headers
with the address length filled correctly.
