In puppetlabs#1129 the 3
functions from this module were ported to the modern function API and
namespaced.  None of the boilerplate was fixed up, tests weren't
updated, documentation wasn't updated etc.

This commit finishes the work for the `postgresql_password` function.

* Remove old API `puppet/parser/functions` version.
* Create a replacement non-namespaced, (but deprecated), new API shim
that calls the namespaced version.
* Replace argument validation in the function code with data-type based
validation for the individual function parameters.
* Update the README and REFERENCE.md files.
* Test both shim and namespaced version of the function.

This commit finishes the work for the `postgresql_escape` function.

* Remove old API puppet/parser/functions version.
* Create a replacement non-namespaced, (but deprecated), new API shim
  that calls the namespaced version. This function is *probably* not
  being used outside of this module, but it doesn't hurt to get the old
  version around for now.
* Replace argument validation in the function code with data-type based
  validation for the individual function parameters.
* Refactor function for increased readability.
* Test both shim and namespaced version of the function.
* Update `postgresql::server` to use namespaced version.
* Update REFERENCE.md

This commit finishes the work for the
`postgresql_acls_to_resources_hash` function.

The existing function documentation made it pretty clear that this
function is for internal use only.  As such, I've marked it `@api
private` and haven't created a non-namespaced shim (like I've being
doing with the other functions in this module).
