Mark BIO_buffer_get_num_lines(3) as intentionally undocumented.

Contrary to what bio.h says, it does not *not* retrieve some "IO type",
whatever that is supposed to be, but it is a NOOP, and nothing uses it.
Despite its name, it is unrelated to BIO_f_buffer(3), and please
be careful to not confuse it with BIO_get_buffer_num_lines(3).
