[oe] SSL Certificate Path for Python

[Ash Charles]

Hi,

With the move from python 2.7.3 (dizzy) to 2.7.9 (fido), Python
actually validates SSL-transport for https URLs [1].  Python, by
default (i.e. no environment variable SSL_CERT_DIR set), looks for
certificates at '/usr/lib/ssl/certs'.  I tested this in a Python
shell:
import ssl
ssl.get_default_verify_paths()

The ca-certificates recipe seems to be installing certificates to
${D}${sysconfdir}/ssl/certs or /usr/share/ca-certificates/mozilla/
instead.  I think that Python will need a way to find the system's
certificates.  I can create a patch to do this but this seems to
couple the configuration in the ca-certificates and python recipes.

Has anyone stumbled across this issue?  Is there a standard way of
looking up where a system is storing its certificates?

Thanks for any insights---I'm learning much more about SSL
certificates than I expected today ;-).
