Mention a few standard BIO_ctrl(3) command constants
that provide type-specific functionality here,
and add the missing return type to one function prototype.

Mark a number of BIO_ctrl(3) command constants as intentionally
undocumented because they are NOOPs or deprecated.

Document those BIO_ctrl(3) command constants
that correspond to more than one macro each.

Document the RETURN VALUES of BIO_method_type(3) and BIO_method_name(3)
for the various BIO types.

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

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).

jmc@ dislikes a comma before "then" in a conditional, so leave those
untouched.
