make "--runxfail" turn imperative pytest.xfail calls into no ops
(it already did neutralize pytest.mark.xfail markers)
Adding test capturing #366 where an error occurs when package resources are loaded from the test package.

add changelog entry: refine pytest / pkg_resources interactions: The
AssertionRewritingHook PEP302 compliant loader now registers itself with
setuptools/pkg_resources properly so that the
pkg_resources.resource_stream method works properly.  Fixes issue366.
Thanks for the investigations and full PR to Jason R. Coombs.
avoid one surprising case of marker malfunction/confusion::

    @pytest.mark.some(lambda arg: ...)
    def test_function():

would not work correctly because pytest assumes @pytest.mark.some
gets a function to be decorated already.  We now at least detect if this
arg is an lambda and thus the example will work.  Thanks Alex Gaynor
for bringing it up.
