Convert a tuple of ints representing a Python version to one of length
three.
:param py_version_info: a tuple of ints representing a Python version,
or None to specify no version. The tuple can have any length.
:return: a tuple of length three if `py_version_info` is non-None.
Otherwise, return `py_version_info` unchanged (i.e. None).

Convert a bytes (or text) path to text (unicode in Python 2) for display

This function should never error out. Also, this function is mainly needed
for Python 2 since in Python 3 str paths are already text.

Return a list of installed Distribution objects.
If ``local_only`` is True (default), only return installations
local to the current virtualenv, if in a virtualenv.
``skip`` argument is an iterable of lower-case project names to
ignore; defaults to stdlib_pkgs
If ``include_editables`` is False, don't report editables.
If ``editables_only`` is True , only report editables.
If ``user_only`` is True , only report installations in the user
site directory.
If ``paths`` is set, only report the distributions present at the
specified list of locations.

Return the path for the .egg-link file if it exists, otherwise, None.
There's 3 scenarios:
1) not in a virtualenv
try to find in site.USER_SITE, then site_packages
2) in a no-global virtualenv
try to find in site_packages
3) in a yes-global virtualenv
try to find in site_packages, then site.USER_SITE
(don't look in global location)
For #1 and #3, there could be odd cases, where there's an egg-link in 2
locations.
This method will just return the first one found.
