...to (remote, local), reflecting the (correct) names in the implementation of
DeliverNetworkPacket (see tcpip/stack/nic.go).
Also trim the names in DeliverNetworkPacket and elsewhere to avoid stuttering;
since the type is tcpip.LinkAddress, there's no need to include "LinkAddr" in
the parameter names.
Note that every callsite passes arguments in the order (src, dst).

Previously, if address resolution for UDP or Ping sockets required sending
packets using Write in Transport layer, Resolve would return ErrWouldBlock
and Write would return ErrNoLinkAddress. Meanwhile startAddressResolution
would run in background. Further calls to Write using same address would also
return ErrNoLinkAddress until resolution has been completed successfully.
Since Write is not allowed to block and System Calls need to be
interruptible in System Call layer, the caller to Write is responsible for
blocking upon return of ErrWouldBlock.
Now, when startAddressResolution is called a notification channel for
the completion of the address resolution is returned.
The channel will traverse up to the calling function of Write as well as
ErrNoLinkAddress. Once address resolution is complete (success or not) the
channel is closed. The caller would call Write again to send packets and
check if address resolution was compeleted successfully or not.
Fixes google/gvisor#5

This allows a NetworkDispatcher to implement transparent bridging,
assuming all implementations of LinkEndpoint.WritePacket call eth.Encode
with header.EthernetFields.SrcAddr set to the passed
Route.LocalLinkAddress, if it is provided.

Makes it possible to avoid copying or allocating in cases where DeliverNetworkPacket (rx)
needs to turn around and call WritePacket (tx) with its VectorisedView.
Also removes the restriction on having VectorisedViews with multiple views in the write path.

We have been unnecessarily creating too many savable types implicitly.

Establishes a way of communicating interface flags between netstack and
epsocket. More flags can be added over time.
