Update x509.load_certificate and related functions to return
python-cryptography ``Certificate`` objects. Update the call sites
accordingly, including removal of NSS initialisation code.
Also update GeneralName parsing code to return python-cryptography
GeneralName values, for consistency with other code that processes
GeneralNames. The new function, `get_san_general_names`, and
associated helper functions, can be removed when python-cryptography
provides a way to deal with unrecognised critical extensions.
