Jason A. Donenfeld 54dbe2471f conn: reconstruct v4 vs v6 receive function based on symtab
This is kind of gross but it's better than the alternatives.

Josh Bleecher Snyder 10533c3e73 all: make conn.Bind.Open return a slice of receive functions
Instead of hard-coding exactly two sources from which
to receive packets (an IPv4 source and an IPv6 source),
allow the conn.Bind to specify a set of sources.

Beneficial consequences:

* If there's no IPv6 support on a system,
  conn.Bind.Open can choose not to return a receive function for it,
  which is simpler than tracking that state in the bind.
  This simplification removes existing data races from both
  conn.StdNetBind and bindtest.ChannelBind.
* If there are more than two sources on a system,
  the conn.Bind no longer needs to add a separate muxing layer.

David Crawshaw 203554620d conn: introduce new package that splits out the Bind and Endpoint types
The sticky socket code stays in the device package for now,
as it reaches deeply into the peer list.

This is the first step in an effort to split some code out of
the very busy device package.
