Introduce the possibility to access global variables through
functions on platform were that's the best way to handle exporting
global variables in shared libraries. To enable this functionality,
one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
"OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
is normally done by Configure or something similar).

To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
in the source file (foo.c) like this:

OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
OPENSSL_IMPLEMENT_GLOBAL(double,bar);

To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:

OPENSSL_DECLARE_GLOBAL(int,foo);
#define foo OPENSSL_GLOBAL_REF(foo)
OPENSSL_DECLARE_GLOBAL(double,bar);
#define bar OPENSSL_GLOBAL_REF(bar)

The #defines are very important, and therefore so is including the
header file everywere where the defined globals are used.

The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
of ASN.1 items, but that structure is a bt different.

The largest change is in util/mkdef.pl which has been enhanced with
better and easier to understand logic to choose which symbols should
go into the Windows .def files as well as a number of fixes and code
cleanup (among others, algorithm keywords are now sorted
lexicographically to avoid constant rewrites).

Modify mkdef.pl to recognise and parse prprocessor conditionals of the
form '#if defined(...) || defined(...) || ...' and '#if !defined(...)

special cases it was previously handling (some of them wrongly).

Make all configuration macros available for application by making
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.

Do not insert things in syms{} and kind{} when parsing the header
files. Instead, insert proper information in the $def string, which
will be properly munged later on.

Various Win32 related fixed. Make no-krb5 work in mkdef.pl .

Remove definitions of deleted functions.

Add missing definition of X509_VAL.

* detect "unknown" algorithms (any C macro starting with NO_ that is
not explicitely mentioned in mkdef.pl as a known algorithm) and

* add a number of algorithms that can be deselected.
* look in ssl/kssl.h as well.
* accept multiple whitespace (not just one SPC) in preprocessor lines.

At the same time, add VMS support for Rijndael.

Oops, no engine in the main trunk.

mkdef.pl still needed better logic. Also, the semantics of the
platforms list is clarified (it's however not quite followed in the
RSAREF case...).

RSAREF is also checked now.

mkdef.pl has erroneous conditions to check if a symbol is excluded
from the given target. Fixed, I hope.

specific symbol to exist.

This was needed for the work I'm doing with shared libraries under
VMS.
