Make RSA_sign.pod less confusing.

Browse Source 
PKCS #1 v2.0 is the name of a document which specifies an algorithm
RSASSA-PKCS1-v1_5, often referred to as "PKCS #1 v1.5" after an earlier
document which specified it. This gets further confusing because the
document PKCS #1 v2.1 specifies two signature algorithms,
RSASSA-PKCS1-v1_5 and RSASSA-PSS. RSA_sign implements RSASSA-PKCS1-v1_5.

Refer to the document using the RFC number which is easier to find
anyway, and refer to the algorithm by its name.

=head1 DESCRIPTION
RSA_sign() signs the message digest B<m> of size B<m_len> using the
private key B<rsa> as specified in PKCS #1 v2.0. It stores the
signature in B<sigret> and the signature size in B<siglen>. B<sigret>
must point to RSA_size(B<rsa>) bytes of memory.
private key B<rsa> using RSASSA-PKCS1-v1_5 as specified in RFC 3447. It
stores the signature in B<sigret> and the signature size in B<siglen>.
B<sigret> must point to RSA_size(B<rsa>) bytes of memory.
Note that PKCS #1 adds meta-data, placing limits on the size of the
key that can be used.
