I guess you guys already found a solution that works, but there's yet
another function, "BIO *BIO_new_mem_buf(void *data, int len)", that we
could use. We could open and read the file all by ourselves into memory,
then call BIO_new_mem_buf and pass that to PEM_read_X509. No need to
pass around file pointers, and we could handle any file I/O errors
ourselves. Presumably certificates are never very big, so reading it all
in memory shouldn't be a problem.

BIO_new_mem_buf was introduced in OpenSSL 0.9.7. What versions do we
support?
