zlib constants were previously being added to binding in node_zlib.cc. This moves the zlib constants to node_constants.cc for consistency with the recent constants refactoring: https://github.com/nodejs/node/pull/6534 Adds require('zlib').constants to expose the constants Docs-only deprecates the constants hung directly off require('zlib') Removes a couple constants from the docs that apparently no longer exist in the code PR-URL: https://github.com/nodejs/node/pull/7203 Reviewed-By: Rod Vagg <rod@vagg.org> Reviewed-By: Anna Henningsen <anna@addaleax.net> Reviewed-By: Ben Noordhuis <info@bnoordhuis.nl>
