Added Tests for latex(pdf) links to captioned or named literal blocks

As conf.py has now numfig = True, needed to modify accordingly test for
links in html output.

This topic branch fixes #2405, #2414, and also makes for latex(pdf)
functional hyperlinks to named references, but only for literal blocks
(code-block or literalinclude).
