Add SHA2 algorithms to SSL_library_init(). Although these aren't used
directly by SSL/TLS SHA2 certificates are becoming more common and
applications that only call SSL_library_init() and not
OpenSSL_add_all_alrgorithms() will fail when verifying certificates.
Update docs.

=head1 WARNING
-SSL_library_init() mainly adds ciphers and digests used directly by SSL/TLS.
-In some cases this is not sufficient and errors about unknown algorithms
-will occur: for example when an attempt is made to use a certificate using
-SHA256. This can be resolved by also calling OpenSSL_add_all_algorithms().
+SSL_library_init() adds ciphers and digests used directly and indirectly by
+SSL/TLS.
=head1 EXAMPLES
A typical TLS/SSL application will start with the library initialization,
-will provide readable error messages and will seed the PRNG.
+and provide readable error messages.
SSL_load_error_strings(); /* readable error messages */
SSL_library_init(); /* initialize library */
- actions_to_seed_PRNG();
=head1 RETURN VALUES
SSL_library_init() always returns "1", so it is safe to discard the return
value.
+=head1 NOTES
+
+OpenSSL 0.9.8o and 1.0.0a and later added SHA2 algorithms to SSL_library_init().
+Applications which need to use SHA2 in earlier versions of OpenSSL should call
+OpenSSL_add_all_algorithms() as well.
