Add support for X509_NAME_print_ex() in req.

Initial code for cutomizable X509 print routines.

Update PKCS12_parse().

Make the keyid in certificate aux info more usable.

centralise those hacks in crypto/symhacks.h and use it everywhere it's
needed.

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 :-(

Add new option to PKCS7_sign to exclude S/MIME capabilities.

Add DER public key routines.

Add -passin argument to 'ca' utility.

Document sign and verify options to dgst.

Document the new DN printing options.

Change a few names to be more meaningful.

Fix typos in CA.pl docs.

New ASN1_STRING_print_ex() and X509_NAME_print_ex()
functions. These are intended to be replacements
for the ancient ASN1_STRING_print() and X509_NAME_print()
functions.

The new functions support RFC2253 and various pretty
printing options. It is also possible to display
international characters if the terminal properly handles
UTF8 encoding (Linux seems to tolerate this if the
"unicode_start" script is run).

Still needs to be documented, integrated into other
utilities and extensively tested.

ASN1_TIME fixes.

New function c2i_ASN1_OBJECT().

Handle ASN1_SET_OF and PKCS12_STACK_OF using function
casts in the same way as STACK_OF.

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.

yet tighter, and also put some heat on the rest of the library by
insisting (correctly) that compare callbacks used in stacks are prototyped
with "const" parameters. This has led to a depth-first explosion of
compiler warnings in the code where 1 constification has led to 3 or 4
more. Fortunately these have all been resolved to completion and the code
seems cleaner as a result - in particular many of the _cmp() functions
should have been prototyped with "const"s, and now are. There was one
little problem however;

X509_cmp() should by rights compare "const X509 *" pointers, and it is now
declared as such. However, it's internal workings can involve
recalculating hash values and extensions if they have not already been
setup. Someone with a more intricate understanding of the flow control of
X509 might be able to tighten this up, but for now - this seemed the
obvious place to stop the "depth-first" constification of the code by
using an evil cast (they have migrated all the way here from safestack.h).

Fortunately, this is the only place in the code where this was required
to complete these type-safety changes, and it's reasonably clear and
commented, and seemed the least unacceptable of the options. Trying to
take the constification further ends up exploding out considerably, and
indeed leads directly into generalised ASN functions which are not likely
to cooperate well with this.

"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.

where the new functions are mentioned.

This better reflects their behaviour.

Tidy up CRYPTO_EX_DATA structures.

that can automatically determine the type of a DER encoded
"traditional" format private key and change some of the
d2i functions to use it instead of requiring the application
to work out the key type.

represent everything by OIDs.

more utilities.

either and has a static and dynamic mix.

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.
