[PATCH v2 RESEND 3/5] git-p4: add raw option to read_pipelines

[Joel Holdsworth <jholdsworth@nvidia.com>]

Previously the read_lines function always decoded the result lines. In
order to improve support for non-decoded binary processing of data in
git-p4.py, this patch adds a raw option to the function that allows
decoding to be disabled.
