Fixes for Win32 build.

This is mostly a work around for the old VC++ problem
that it treats func() as func(void).

Various prototypes had been added to 'compare' function
pointers that triggered this. This could be fixed by removing
the prototype, adding function pointer casts to every call or
changing the passed function to use the expected arguments.
I mostly did the latter.

The mkdef.pl script was modified to remove the typesafe
functions which no longer exist.

Oh and some functions called OPENSSL_freeLibrary() were
changed back to FreeLibrary(), wonder how that happened :-)

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

Also, make sure empty slots of the dynamic lock stack are used.
Actually, I'm not really sure this is the right thing to do, and may
remove it, with an endlessly growing stack as result...

insecure, so a static lock is added to isolate the sensitive parts.
Also, to avoid one thread freeing a lock that is used by another, a
reference counter is added.

any more.

be needed in some ENGINE code, and might serve elsewhere as well.
Note that it's implemented in such a way that the locking itself is
done through the same CRYPTO_lock function as the static locks.

WARNING: This is currently experimental and untested code (it will get
tested soon, though :-)).

type-specific stack function.  Second, even when we don't build any of
those functions, DECLARE_STACK_OF lines should not find themselves
into $def.

sk_whatever_insert and sk_whatever_set immediately reveals the subtle
difference in parameter order.

Change mkstack.pl so that safestack.h is not rewritten when
nothing has changed.

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.

As far as I understand, it still needs to be compiled on NT...

"symbols" including functions (of all prototypes( and variables. Whilst
casting any function type to another violates ANSI C (I believe), it is
a necessary evil in shared-library APIs. However, it is quite
conceivable that functions in general and data symbols could very well
be represented differently to each other on some systems, as Bodo said;

I agree. So this change splits the "dso_bind" handler in DSO_METHOD
into "dso_bind_var" and "dso_bind_func". Similarly the exported
function DSO_bind() has been split in two. I've also put together
changes for the various DSO_METHOD implementations, but so far only
DSO_dlfcn() has been tested. BTW: The prototype for dso_bind had been
a bit strange so I've taken the opportunity to change its shape (in
both variations).

Also, the README has been updated - particularly with a note about
using customised native name-translation for shared libraries (and that
you can't do it yet).

BN_mod_exp_atalla could be used.

BN_mod_exp. Call the regular atalla mod_exp operation instead.

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.

Documentation correction.

EVP_DecryptInit() return values.

Update docs.

as expected -- maybe it's the different processor, maybe my
previous timings were too inaccurate.

Don't give performance gain estimates that appear to be more precise
than they really are, especially when they are wrong

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.
