Merge from the ASN1 branch of new ASN1 code
to main trunk.

Lets see if the makes it to openssl-cvs :-)

make update done.

acceptable, since all that happens if it fails is a library with
an index, which makes linking slower, but still working correctly.

of complaints from the compiler about data pointers and function
pointers not being compatible with each other.

the OpenSSL commands x50 and req work better on a EBCDIC system.

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 :-(

MD4 implemented.  Assar Westerlund provided the digest code itself and the test utility, I added the bits to get a EVP interface, the command line utility and the speed test

could be done automagically, much like the numbering in libeay.num and
ssleay.num.  The solution works as follows:

  - New object identifiers are inserted in objects.txt, following the
    syntax given in objects.README.
  - objects.pl is used to process obj_mac.num and create a new
    obj_mac.h.
  - obj_dat.pl is used to create a new obj_dat.h, using the data in
    obj_mac.h.

This is currently kind of a hack, and the perl code in objects.pl
isn't very elegant, but it works as I intended.  The simplest way to
check that it worked correctly is to look in obj_dat.h and check the
array nid_objs and make sure the objects haven't moved around (this is
important!).  Additions are OK, as well as consistent name changes.

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.

Also, "make update" has added some missing functions to libeay.num,
updated the TABLE for the alpha changes, and updated thousands of
dependancies that have changed from recent commits.

New function to retrieve email address from certificates and
requests.

like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages.  That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.

This change includes all the name changes needed throughout all C files.

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.

Update the ca-cert.pem and pca-cert.pem "CA" certificates so they
