Rich Salz 9b86974e0c Fix L<> content in manpages
L<foo|foo> is sub-optimal  If the xref is the same as the title,
which is what we do, then you only need L<foo>.  This fixes all
1457 occurrences in 349 files.  Approximately.  (And pod used to
need both.)

=head1 NAME
SSL_get_ciphers, SSL_get_cipher_list - get list of available SSL_CIPHERs
=head1 SYNOPSIS
#include <openssl/ssl.h>
STACK_OF(SSL_CIPHER) *SSL_get_ciphers(const SSL *ssl);
STACK_OF(SSL_CIPHER) *SSL_get_client_ciphers(const SSL *ssl);
const char *SSL_get_cipher_list(const SSL *ssl, int priority);
=head1 DESCRIPTION
SSL_get_ciphers() returns the stack of available SSL_CIPHERs for B<ssl>,
sorted by preference. If B<ssl> is NULL or no ciphers are available, NULL
is returned.
SSL_get_client_ciphers() returns the stack of available SSL_CIPHERS matching the
list sent by the client for B<ssl>. If B<ssl> is NULL, no ciphers are
available, or B<ssl> is not operating in server mode, NULL is returned.
SSL_get_cipher_list() returns a pointer to the name of the SSL_CIPHER
listed for B<ssl> with B<priority>. If B<ssl> is NULL, no ciphers are
available, or there are less ciphers than B<priority> available, NULL
is returned.
=head1 NOTES
The details of the ciphers obtained by SSL_get_ciphers() can be obtained using
the L<SSL_CIPHER_get_name(3)> family of functions.
Call SSL_get_cipher_list() with B<priority> starting from 0 to obtain the
sorted list of available ciphers, until NULL is returned.
Note: SSL_get_ciphers() and SSL_get_client_ciphers() return a pointer
to an internal cipher stack, which will be freed later on when the SSL
or SSL_SESSION object is freed. Therefore, the calling code B<MUST
NOT> free the return value itself.
