Renaming x509_get_subject_alt_name to x509_get_general_names and mbedtls_x509_parse_subject_alt_name to mbedtls_x509_parse_general_name so they can be used not only to collect subject alt name, but the V3 authority cert issuer that is also GeneralName type.
Also updated the x509_get_general_names function to be able to parse rfc822Names

Test are also updated according these changes.
