sslutil: try to find CA certficates in well-known locations
Many Linux distros and other Nixen have CA certificates in well-defined
locations. Rather than potentially fail to load any CA certificates at
all (which will always result in a certificate verification failure),
we scan for paths to known CA certificate files and load one if seen.
Because a proper Mercurial install will have the path to the CA
certificate file defined at install time, we print a warning that
the install isn't proper and provide a URL with instructions to
correct things.
We only perform path-based fallback on Pythons that don't know
how to call into OpenSSL to load the default verify locations. This
is because we trust that Python/OpenSSL is properly configured
and knows better than Mercurial. So this new code effectively only
runs on Python <2.7.9 (technically Pythons without the modern ssl
module).
