Rich Salz a528d4f0a9 Remove SSLeay history, etc., from docs
If something was "present in all versions" of SSLeay, or if it was
added to a version of SSLeay (and therefore predates OpenSSL),
remove mention of it.  Documentation history now starts with OpenSSL.

Remove mention of all history before OpenSSL 0.9.8, inclusive.

Remove all AUTHOR sections.

=head1 NAME
DH_size, DH_bits - get Diffie-Hellman prime size
=head1 SYNOPSIS
#include <openssl/dh.h>
int DH_size(const DH *dh);
int DH_bits(const DH *dh);
=head1 DESCRIPTION
DH_size() returns the Diffie-Hellman prime size in bytes. It can be used
to determine how much memory must be allocated for the shared secret
computed by DH_compute_key().
DH_bits() returns the number of significant bits.
B<dh> and B<dh-E<gt>p> must not be B<NULL>.
=head1 RETURN VALUE
The size.
=head1 SEE ALSO
L<dh(3)>, L<DH_generate_key(3)>,
L<BN_num_bits(3)>
=head1 HISTORY
DH_bits() was added in OpenSSL 1.1.0.
