Use mainline Rebar (v2)

[lag-linaro]

This PR uses the latest software provided by the upstream Rebar (v2) repo.

The most significant change allows this version of Rebar to work with compilers which do not support the -m64 flag, as reported in #892 amongst others.

The latest code base also contains @davisp's Properly skip apps with a .app.src.script file patch with CouchDB has been carrying for a while now.

Unfortunately, we cannot accept this PR, as none of our dependencies can be on repositories outside of the Apache organization directly.

You can try a PR against the apache/couchdb-rebar repository if you want...

Sorry about this.

Also, we have a strong preference to migrate the build process to rebar 3 - #1428. If you are able to help with this conversion process, we'll be especially grateful.

That's okay. I will update CouchDB's Rebar repo instead.

Yes, I am aware of that, and I'm happy to help.

NB: I would still like to see Rebar v2 updated in the mean time please.

I did briefly investigate moving to Rebar3, but I didn't find the code to update.

How does one compile native code with @davisp's offering? Where is the NIF code?
