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_CTX_get0_param, SSL_get0_param, SSL_CTX_set1_param, SSL_set1_param -
get and set verification parameters
=head1 SYNOPSIS
#include <openssl/ssl.h>
X509_VERIFY_PARAM *SSL_CTX_get0_param(SSL_CTX *ctx)
X509_VERIFY_PARAM *SSL_get0_param(SSL *ssl)
int SSL_CTX_set1_param(SSL_CTX *ctx, X509_VERIFY_PARAM *vpm)
int SSL_set1_param(SSL *ssl, X509_VERIFY_PARAM *vpm)
=head1 DESCRIPTION
SSL_CTX_get0_param() and SSL_get0_param() retrieve an internal pointer to
the verification parameters for B<ctx> or B<ssl> respectively. The returned
pointer must not be freed by the calling application.
SSL_CTX_set1_param() and SSL_set1_param() set the verification parameters
to B<vpm> for B<ctx> or B<ssl>.
=head1 NOTES
Typically parameters are retrieved from an B<SSL_CTX> or B<SSL> structure
using SSL_CTX_get0_param() or SSL_get0_param() and an application modifies
them to suit its needs: for example to add a hostname check.
=head1 EXAMPLE
Check hostname matches "www.foo.com" in peer certificate:
X509_VERIFY_PARAM *vpm = SSL_get0_param(ssl);
X509_VERIFY_PARAM_set1_host(vpm, "www.foo.com", 0);
=head1 RETURN VALUES
SSL_CTX_get0_param() and SSL_get0_param() return a pointer to an
B<X509_VERIFY_PARAM> structure.
SSL_CTX_set1_param() and SSL_set1_param() return 1 for success and 0
for failure.
=head1 SEE ALSO
L<X509_VERIFY_PARAM_set_flags(3)>
=head1 HISTORY
These functions were first added to OpenSSL 1.0.2.
