This patch replaces a bash based generator with a python generator. This
has the obvious advantage of remove a large swath of generated tests
from the check-in, and prevents modification of a generated file. It
also is much faster than the bash generator, so running at compile time
isn't a problem.

There are no functional differences between the bash generated versions
and the python generated versions, only whitespace/line-wrapping
differences, and small changes to the copyright header.

All tests that passed with the bash versions pass with the python
versions on the i965 driver with multiple hardware revisions.

Tested with python2.7 and python3.3

v2: - rename generated test .list file (Emil)
    - Use a shared function to add the license text
      (also removes a typo in the text spotted by Emil)
