[issue19375] Deprecate site-python in site.py

[Antoine Pitrou]

New submission from Antoine Pitrou:

I suggest deprecating the "site-python" feature from site.py, as proposed by Guido on python-dev:
https://mail.python.org/pipermail/python-dev/2013-October/129820.html

- if a "site-python" directory is detected and added from site.py, a DeprecationWarning should be emitted
- the site.py docs should mention the deprecation
