scd:p15: Prepare AODF parsing for other authentication types.
* scd/app-p15.c (auth_type_t): New. (struct aodf_object_s): Add field auth_type. (read_ef_aodf): Distinguish between pin and authkey types. Include the authtype in the verbose mode diags. -- Note that the bulk of changes are just indentation changes. There should be no functional change. Signed-off-by: Werner Koch <wk@gnupg.org> (cherry picked from commit e387cc97c82313457e4f79729a137e5871891bc1)
