Part 2 of fix for #1175 (functions in environments)

Jesse and I are shooting for the minimal viable fix here, with the idea that
a great deal of refactoring is needed but isn't appropriate at this time.  The
changes in this commit are:

* Index the function-holding modules by environment

* We need to know the "current environment" when we're defining a function so
we can attach it to the proper module, and this information isn't dynamically
available when user-defined functions are being created (we're being called by
user written code that doesn't "know" about environments) so we cheat and
stash the value in Puppet::Node::Environment

* since we must do this anyway, it turns out to be cleaner & safer to do the
same when we are evaluating a functon.  This is the main change from the prior
version of this patch.

* Add a special *root* environment for the built in functions, and extend all
scopes with it.

* Index the function characteristics (name, type, docstring, etc.) by environment

* Make the autoloader environment aware, so that it uses the modulepath for the
specified environment rather than the default

* Turn off caching of the modulepath since it potentially changes for each node

* Tweak tests that weren't environment aware
