Make BIO_info_cb() identical to bio_info_cb()

Make BIO_info_cb() identical to bio_info_cb()

Various projects use bio_info_cb and BIO_info_cb interchangeably, for
example mupdf and freerdp. This is because this was changed in OpenSSL
commit fce78bd4 (2017), triggered by new warnings in gcc 8.

https://github.com/openssl/openssl/pull/4493

This results in some scary compiler warnings and useless patches in ports.
Nobody seems to be using the old bio_info_cb() version.
