message make ether_output with AF_MPLS use a routes gateway address if available

sending an MPLS frame is weird compared to other address families.
other families figure out and pass the address on the local link
for ether_output to use for resolution, but AF_MPLS basically passes
a dummy sockaddr so ether_output can get the ethernet protocol field
right. ether_output then has to pull the route apart to figure out
which address and family to use for address resolution on the local
net. eg, MPLS tagged routes via ip addresess need to pull the route
apart and get at the AF_INET sockaddr to pass to arpresolve. that
code currently uses the destination address of the route, but if
that destination is not on the local network, we'd end up using it
for arp requests that don't work.

this change uses the rt_gateway sockaddr if RTF_GATEWAY is set.
this solves the problem in my testing and doesn't seem to break
other uses cases ive tried.

i wrote this in mpe before porting and committing it in mpw, but

message replace sc_flgas with sc_cword

the only flag used with sc_flags was the one to turn the control
word on and off.

this is in preparation for split ioctls for controlling pseudowire
behaviour. sc_cword can be set atomically and indepentently as a
separate variable.

message don't store the BOS flag as part of the remote label, add it at tx time.

message add support for rfc 6391: flow-aware transport of pseudowires.

this basically adds a dummy mpls tag to the stack for pseudowires
and uses a flow as the label on that dummy tag. this allows
intermediate systems that hash packets onto multiple links to use
the extra tag as input to the hash, providing more entropy and
therefore better load balancing.

it's a pity there's no way to turn it on yet...

ioctl(WSMUXIO_ADD_DEVICE), two distinct locks of the same type are

check by flagging the locks as RWL_DUPOK.
