[oe] [meta-networking][PATCH] nng: Add recipe

[Tom Rini]

nng is the nanomsg project's rewrite of their libnanomsg library.  Just
like nanomsg it is a socket library that provides several common
communication patterns.

Unlike nanomsg it does not normally provide a number of tools and we do
not attempt to add them here.  We allow for optional mbedtls support.

Notes:
- nng is not a 1-to-1 replacement for nanomsg and does provide different
  runtime files, so we do not conflict/etc with them.
- nng does support cross-compilation of tools but I'm leaving this out
  as I can't test that currently and it is non-default.
- As it's part of the nanomsg project I am putting this under the
  nanomsg folder, but I don't have strong preferences here.
