Rich Salz 53934822ac Clean up "generic" intro pod files.
Files like dh.pod, etc., mostly duplicated the API-specific pod files.
Removed the duplicated content; that often mean the whole file could
be removed.  Some of the content about internals got moved into README
files in the source tree.  Some content (e.g., err.pod) got moved
into other pod pages.

Annotate generic pages, remove dup NAME

=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<BN_num_bits(3)>
=head1 HISTORY
RSA_bits() was added in OpenSSL 1.1.0.
