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
RSA_size, RSA_bits - get RSA modulus size
=head1 SYNOPSIS
#include <openssl/rsa.h>
int RSA_size(const RSA *rsa);
int RSA_bits(const RSA *rsa);
=head1 DESCRIPTION
RSA_size() returns the RSA modulus size in bytes. It can be used to
determine how much memory must be allocated for an RSA encrypted
value.
RSA_bits() returns the number of significant bits.
B<rsa> and B<rsa-E<gt>n> must not be B<NULL>.
=head1 RETURN VALUE
The size.
=head1 SEE ALSO
L<rsa(3)>, L<BN_num_bits(3)>
=head1 HISTORY
RSA_bits() was added in OpenSSL 1.1.0.
