d095b68d63 Deprecate quite a few recursive includes from the ssl.h API header and
remove some unnecessary includes from the internal header ssl_locl.h. This
then requires adding includes for bn.h in four C files.

2754597013 A general spring-cleaning (in autumn) to fix up signed/unsigned warnings.
I have tried to convert 'len' type variable declarations to unsigned as a
means to address these warnings when appropriate, but when in doubt I have
used casts in the comparisons instead. The better solution (that would get
us all lynched by API users) would be to go through and convert all the
function prototypes and structure definitions to use unsigned variables
except when signed is necessary. The proliferation of (signed) "int" for
strictly non-negative uses is unfortunate.

7b63c0fa8c Reorder inclusion of header files:
des_old.h redefines crypt:
#define crypt(b,s)\
        DES_crypt((b),(s))

This scheme leads to failure, if header files with the OS's true definition
of crypt() are processed _after_ des_old.h was processed. This is e.g. the
case on HP-UX with unistd.h.
As evp.h now again includes des.h (which includes des_old.h), this problem
only came up after this modification.
Solution: move header files (indirectly) including e_os.h before the header
files (indirectly) including evp.h.

882e891284 More Kerberos SSL changes from Jeffrey Altman <jaltman@columbia.edu>
His comments are:

First, it corrects a problem introduced in the last patch where the
kssl_map_enc() would intentionally return NULL for valid ENCTYPE
values.  This was done to prevent verification of the kerberos 5
authenticator from being performed when Derived Key ciphers were
in use.  Unfortunately, the authenticator verification routine was
not the only place that function was used.  And it caused core dumps.

Second, it attempt to add to SSL_SESSION the Kerberos 5 Client
Principal Name.

2a1ef75435 Patches from Vern Staats <staatsvr@asc.hpc.mil> to get Kerberos 5 in
SSL according to RFC 2712.  His comment is:

This is a patch to openssl-SNAP-20010702 to support Kerberized SSL
authentication.  I'm expecting to have the full kssl-0.5 kit up on
sourceforge by the end of the week.  The full kit includes patches
for mod-ssl, apache, and a few text clients.  The sourceforge URL
is http://sourceforge.net/projects/kssl/ .

Thanks to a note from Simon Wilkinson I've replaced my KRB5 AP_REQ
message with a real KerberosWrapper struct.  I think this is fully
RFC 2712 compliant now, including support for the optional
authenticator field.  I also added openssl-style ASN.1 macros for
a few Kerberos structs; see crypto/krb5/ if you're interested.

ccd86b68ef The previous commit to crypto/stack/*.[ch] pulled the type-safety strings
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.

9d5cceac6f No actual change, but the cert_st member of struct ssl_session_st is now
called sess_cert instead of just cert.  This is in preparation of further
changes: Probably often when s->session->sess_cert is used, we should
use s->cert instead; s->session->sess_cert should be a new structure
containing only the stuff that is for just one connection (e.g.
the peer's certificate, which the SSL client implementations currently
store in s->session->[sess_]cert, which is a very confusing thing to do).
