This is currently *very* experimental and needs to be more fully integrated
with the main verification code.

when X509_V_FLAG_X509_STRICT is set. Check for CRLSign in
CRL issuer certificates. Reject CRLs with unhandled (any)
critical extensions.

Reject certificates with unhandled critical extensions.

See the commit log message for that for more information.

NB: X509_STORE_CTX's use of "ex_data" support was actually misimplemented
(initialisation by "memset" won't/can't/doesn't work). This fixes that but
requires that X509_STORE_CTX_init() be able to handle errors - so its
prototype has been changed to return 'int' rather than 'void'. All uses of
that function throughout the source code have been tracked down and
adjusted.

Purpose and trust setting functions for X509_STORE.

inherited from X509_STORE.

Add CRL checking options to other applications.

Initial CRL based revocation checking.

sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

Add support for settable verify time in X509_verify_cert().

Document rsautl utility.

The old code was painfully primitive and couldn't handle
distinct certificates using the same subject name.

The new code performs several tests on a candidate issuer
certificate based on certificate extensions.

It also adds several callbacks to X509_VERIFY_CTX so its
behaviour can be customised.

Unfortunately some hackery was needed to persuade X509_STORE
to tolerate this. This should go away when X509_STORE is
replaced, sometime...

This must have broken something though :-(

After some messing around this seems to work but needs
a few more tests. Working out the syntax for sk_set_cmp_func()
(cast it to a function that itself returns a function pointer)
was painful :-(

Needs some testing to see what other compilers think of this
syntax.

Also needs similar stuff for ASN1_SET_OF etc etc.

was a really bad idea.  For example, the following:

	#include <x509.h>
	#include <bio.h>
	#include <asn1.h>

would make sure that things like ASN1_UTCTIME_print() wasn't defined
unless you moved the inclusion of bio.h to above the inclusion of
x509.h.  The reason is that x509.h includes asn1.h, and the
declaration of ASN1_UTCTIME_print() depended on the definition of
HEADER_BIO_H.  That's what I call an obscure bug.

Instead, this change makes sure that whatever header files are needed
for the correct process of one header file are included automagically,
and that the definitions of, for example, BIO-related things are
dependent on the absence of the NO_{foo} macros.  This is also
consistent with the way parts of OpenSSL can be excluded at will.

libeay.num and ssleay.num.

"Jan Mikkelsen" <janm@transactionsite.com> correctly states that the
OpenSSL header files have #include's and extern "C"'s in an incorrect
order.  Thusly fixed.

Tidy up CRYPTO_EX_DATA structures.

Remove references to 'TXT' in -inform and -outform switches.

SSL_CTX and SSL, functions to set them and defaults if no values set.

yet.

Add a function X509_STORE_CTX_purpose_inherit() which implements the logic
of "inheriting" purpose and trust from a parent structure and using a default:
this will be used in the SSL code and possibly future S/MIME.

Partial documentation of the 'verify' utility. Still need to document how all
the extension checking works and the various error messages.

trust settings of the root CA.

After a few fixes it seems to work OK.

Still need to add support to SSL and S/MIME code though.

at present. However nothing enables it yet so this doesn't
matter :-)

New universal public key format.

Fix CRL+cert load problem in by_file.c
