[Piglit] [PATCH v3 0/3] Add compression support for piglit backends

[Dylan Baker]

This series implements a framework for compressing results in piglit.

The design is such that compression only happens at the end, when
writing the final muxed file. This framework makes it easy for a backend
to implement support for compression, and makes it easy to add
additional compression formats, simply by adding a couple of lines to
framework/backends/compression.py.

This is primarily aimed at the json backend, since junit is meant mainly
for consumption by jenkins, which doesn't understand compressed results.
However, the implementation is such that piglit can consume compressed
junit (as much as junit is supported for reading right now), though it
doesn't support creating compressed junit.

gzip and bzip2 are added, and the superior bzip2 format is set as the
default.

There are two methods provided for changing the compression format,
either by setting [core]:compression in piglit.conf, or by setting
PIGLIT_COMPRESSION in the environment.

This has been tested against Python 3 as well, and requires only a very
small patch to continue working.

Dylan Baker (3):
  framework: Add ability to set a compression method on file backends
  framework: add support for gzip compressionn
  framework: add support for bz2 compression.
