fixes #44 open protocol by "name" (symbol) instead number

fixes #38 Make protocols "pluggable", or at least optional

This is a breaking change, as we've done away with the central
registered list of protocols, and instead demand the user call
nng_xxx_open() where xxx is a protocol name.  (We did keep a
table around in the compat framework though.)

There is a nice way for protocols to plug in via
an nni_proto_open(), where they can use a generic constructor
that they use to build a protocol specific constructor (passing
their ops vector in.)
