Upgrades the impala-shell's bundled version of sqlparse to 0.3.1. There were some API changes in 0.2.0+ that required a re-write of the StripLeadingCommentFilter in impala_shell.py. A slight perf optimization was also added to avoid using the filter altogether if no leading comment is readily discernible. As 0.1.19 was the last version of sqlparse to support python 2.6, this patch also breaks Impala's compatibility with python 2.6. No new tests were added, but all existing tests passed without modification.

To install new packages: 1) Add your package to deps/requirements.txt, or deps/compiled-requirements.txt if the the package needs a C/C++ compiler to build . You should specify the version number using the "foo == x.y.z" notation so future upgrades can be done automatically. 2) Run deps/download_requirements, it will download the package to the deps dir. 3) Run the "impala-python" command, this should detect that requirements.txt changed and automatically rebuild the virtualenv. 4) Now in the python prompt, you should be able to import the new module. To upgrade a package: 1) Edit deps/requirement.txt to use the version you need. 2) Go to step 2 above.
