This completely refactors the `expectsError` behavior: so far it's
almost identical to `assert.throws(fn, object)` in case it was used
with a function as first argument. It had a magical property check
that allowed to verify a functions `type` in case `type` was passed
used in the validation object. This pattern is now completely removed
and `assert.throws()` should be used instead.
The main intent for `common.expectsError()` is to verify error cases
for callback based APIs. This is now more flexible by accepting all
validation possibilites that `assert.throws()` accepts as well. No
magical properties exist anymore. This reduces surprising behavior
for developers who are not used to the Node.js core code base.
This has the side effect that `common` is used significantly less
frequent.

ERR_INVALID_ARG_TYPE is the most common error used throughout the
code base. This improves the error message by providing more details
to the user and by indicating more precisely which values are allowed
ones and which ones are not.
It adds the actual input to the error message in case it's a primitive.
If it's a class instance, it'll print the class name instead of
"object" and "falsy" or similar entries are not named "type" anymore.

- Use assert to check mode in the Zlib constructor since it should
only be passed by us.
- Introduce checkRangesOrGetDefault() and checkFiniteNumber()
to simplify type and range checking for numeric arguments
- Instead of `ERR_INVALID_OPT_VALUE`, throw `ERR_OUT_OF_RANGE` and
`ERR_INVALID_ARG_TYPE` with descriptions of the expected ranges
or types to make the errors more user-friendly.
- Add message tests for the changed errors

There is actually no reason to use `assert.doesNotThrow()` in the
tests. If a test throws, just let the error bubble up right away
instead of first catching it and then rethrowing it.

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

Up to now, `Z_FINISH` was always the flushing flag that was used
for the last chunk of input data. This patch makes this choice
configurable so that advanced users can perform e.g. decompression of
partial data using `Z_SYNC_FLUSH`, if that suits their needs.
Add tests to make sure that an error is thrown upon encountering
invalid `flush` or `finishFlush` flags.
