framework/summary.py: Adds new summary class and two support classes

This new summary class (currently NewSummary), is a complete redesign of
the summary generation system. Much of the code in summary was not
commented, and also not clear as to what it was doing, making it very
difficult to maintain and even more difficult to improve. The other
problem with the code was architecturally it was clobbered together,
doing some of the work in the summary.py file, and some of the work in
the piglit-summary-html.py file.

The new summary class does all of it's work in the summary.py file, and
from an API point of view, in one class. The summary class uses it's
constructor to build lists of passes, failures, skips, problems, etc.
and then uses methods to generate output. The reference implementation
of that kind of method is for generating HTML, but in theory it could be
used to generate anything: XML, CSV lists, printed lists ala
piglit-summary, etc.

Also updates the .gitignore file to ignore some generated content
created by this class.

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

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.
