Change pathnames of local files into ``file://`` URLs with ``#md5=...`` fragments.

When pip-accel calls pip to download missing distribution archives and
the user specified the pathname of a local distribution archive on the
command line, pip will (by default) *not* copy the archive into the
download directory if an archive for the same package name and
version is already present.
This can lead to the confusing situation where the user specifies a
local distribution archive to install, a different (older) archive for
the same package and version is present in the download directory and
`pip-accel` installs the older archive instead of the newer archive.
To avoid this confusing behavior, the :func:`decorate_arguments()`
method rewrites the command line arguments given to ``pip install`` so
that pathnames of local archives are changed into ``file://`` URLs that
include a fragment with the hash of the file's contents. Here's an
example:
- Local pathname: ``/tmp/pep8-1.6.3a0.tar.gz``
- File URL: ``file:///tmp/pep8-1.6.3a0.tar.gz#md5=19cbf0b633498ead63fb3c66e5f1caf6``
When pip fills the download directory and encounters a previously
cached distribution archive it will check the hash, realize the
contents have changed and replace the archive in the download
directory.
