If none of the uids are primary (because none are valid) then pick the
first to be primary (but still invalid). This is for cosmetics in case
some display needs to print a user ID from a non-selfsigned key. Also use
--allow-non-selfsigned-uid to make such a key valid and not
--always-trust. The key is *not* automatically trusted via
--allow-non-selfsigned-uid.
Make sure non-selfsigned uids print [uncertain] on verification even
though one is primary now.
If the main key is not valid, then neither are the subkeys.
Allow --allow-non-selfsigned-uid to work on completely unsigned keys.
Print the uids in UTF8. Remove mark_non_selfsigned_uids_valid()
Show revocation key as UTF8.
Allow --not-dash-escaped to work with v3 keys.
