Adding a unit test to verify the use of the `linenothreshold` option
provided by the `highlight` directive [1]. The included document to test
will introduce two sets of `code-block` and `literalinclude` directives
where the first entry generates contents using line numbers and the
second entry generates contents not using line numbers, respectfully.

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).

* rename a few test modules to make the names more consistent
* do not copy/use Sphinx from build/ (unnecessary without 2to3)
* use a temporary dir for *all* test projects, the source tree
will stay pristine that way (default is tests/build)
* speed up tests by ~3x by splitting up test projects and avoiding
rebuilds
