Maybe there should be a general
   check-no-more-data-in-file(BIO*,bool*bIsPEM)
routine called from the functions that take a file name as
argument, open it as a BIO, loads some PEM data and closes
the BIO, thus giving the caller no opportunity to use (or
check for) any extra PEM blocks (or DER blocks for DER
input).
