piglit-summary-py: Use the new summary class to generate HTML

Drops almost all of the code used in this file, all of that
functionality is now handled in the summary class. Instead, the majority
of this file is just the argparse instance, and a few short lines
calling the new summary class.

templates: Remove old HTML templates

These template files are no longer used, and so they should be removed

templates/index.css: make some css more exclusive

Change the div:nth-child for operating on everything except head to only
working on group. This is lays groundwork for some other changes.

summary: Build subdirectories for subtest result pages

With 10,000+ tests all living in the same folder it can be hard to
identify a single file, especially when trying to work with the HTML
generation itself. This patch changes the behavior so that each test
has a directory tree for the group results with tests under it (ie
spec/GLSL 1.0/foo/bar/test.html)

A side effect of this is that the group names of tests don't have to be
altered to create a valid name (since the slashes in the group names
just become the slashes in the folder structure) and this was the single
most expensive operation of HTML generation (about 1/3 of the total
time). This is a tidy little speedup.

test_result.mako: Drop redundant status and result field

In the old summary code one was set equal to the other, and then
written. In order to produce the same output they were both brought over
to the mako code. But they're rather silly and worthless and only one
should be kept.

HTML summary: Provides means to exclude generating test result files

This provides a switch and method for excluding the generation of the
test result HTML files (those that live under <testrun name>/). This
allows the user to trade some verbosity in the results for a significant
increase in generation speed. A run of quick.tests with all options
enabled takes ~5.5 seconds, with just pass and skip disabled it only
takes ~2.5 seconds. This only becomes more significant as more testsruns
are added the HTML page.

HTML Summary: Don't generate empty pages

Previously every page (fixes, regressions, etc) was generated regardless
of whether there was anything on that page. That is simply silly, this
patch does a quick check and only generates pages that actually have
content, and add those pages to the link bar at the top of the page.

summary.py: Change skip to N/A for tests not run

When comparing two test results the current behavior sets a status of
skip for tests that were not run in one set of results. This is
confusing and silly, so instead give them a status of N/A which gives a
clear understanding of what skipped, and what simply didn't run either
by exclusion or because it didn't exist yet.
