Rich Salz a528d4f0a9 Remove SSLeay history, etc., from docs
If something was "present in all versions" of SSLeay, or if it was
added to a version of SSLeay (and therefore predates OpenSSL),
remove mention of it.  Documentation history now starts with OpenSSL.

Remove mention of all history before OpenSSL 0.9.8, inclusive.

Remove all AUTHOR sections.

=head1 NAME
X509_get_version, X509_set_version, X509_REQ_get_version, X509_REQ_set_version,
X509_CRL_get_version, X509_CRL_set_version - get or set certificate,
certificate request or CRL version.
=head1 SYNOPSIS
#include <openssl/x509.h>
long X509_get_version(X509 *x);
int X509_set_version(X509 *x, long version);
long X509_REQ_get_version(X509_REQ *req);
int X509_REQ_set_version(X509_REQ *x, long version);
long X509_CRL_get_version(X509_CRL *crl);
int X509_CRL_set_version(X509_CRL *x, long version);
=head1 DESCRIPTION
X509_get_version() returns the numerical value of the version field of
certificate B<x>. Note: this is defined by standards (X.509 et al) to be one
less than the certificate version. So a verson 3 certificate will return 2 and
a version 1 certificate will return 0.
X509_set_version() sets the numerical value of the version field of certificate
B<x> to B<version>.
Similarly X509_REQ_get_version(), X509_REQ_set_version(),
X509_CRL_get_version() and X509_CRL_set_version() get and set the version
number of certificate requests and CRLs.
=head1 NOTES
The version field of certificates, certificate requests and CRLs has a
DEFAULT value of B<v1(0)> meaning the field should be omitted for version
1. This is handled transparently by these functions.
=head1 RETURN VALUES
X509_get_version(), X509_REQ_get_version() and X509_CRL_get_version()
return the numerical value of the version field.
X509_set_version(), X509_REQ_set_version() and X509_CRL_set_version()
return 1 for success and 0 for failure.

=head1 HISTORY
X509_get_version(), X509_REQ_get_version() and X509_CRL_get_version() are
functions in OpenSSL 1.1.0, in previous versions they were macros.
