This takes us away from the idea that we know exactly how our static
libraries are going to get used.  Instead, we make them available to
build shareable things with, be it other shared libraries or DSOs.

On the other hand, we also have greater control of when the shared
library cflags.  They will never be used with object files meant got
binaries, such as apps/openssl or test/test*.

With unified, we take this a bit further and prepare for having to
deal with extra cflags specifically to be used with DSOs (dynamic
engines), libraries and binaries (applications).

All those flags existed because we had all the dependencies versioned
in the repository, and wanted to have it be consistent, no matter what
the local configuration was.  Now that the dependencies are gone from
the versioned Makefile.ins, it makes much more sense to use the exact
same flags as when compiling the object files.

As part of this, change util/mkdef.pl to stop adding libraries to
depend on in its output.  mkdef.pl should ONLY output a symbol
vector.

Because symbol names can't be longer than 31 characters, we use the
compiler to shorten those that are longer down to 23 characters plus
an 8 character CRC.  To make sure users of our header files will pick
up on that automatically, add the DEC C supported extra headers files
__decc_include_prologue.h and __decc_include_epilogue.h.

Furthermore, we add a config.com, so VMS people can configure just as

The rand code can aquire locks and then attempt crypto operations. This

This provides support for building in the EDK II reference implementation
of UEFI. Most UEFI firmware in existence uses OpenSSL for implementing
the core cryptographic functionality needed for Secure Boot.

This has always previously been handled with external patches to OpenSSL
but we are now making a concerted effort to eliminate those.

In this mode, we don't actually use the OpenSSL makefiles; we process
the MINFO file generated by 'make files' and incorporate it into the
EDK2 build system.

Since EDK II builds for various targets with varying word size and we
need to have a single prepackaged configuration, we deliberately don't
hard-code the setting of SIXTY_FOUR_BIT vs. THIRTY_TWO_BIT in
opensslconf.h. We bypass that for OPENSSL_SYS_UEFI and allow EDK II
itself to set those, depending on the architecture.

For x86_64, EDK II sets SIXTY_FOUR_BIT and thus uses 'long long' for the
64-bit type, even when building with GCC where 'long' is also 64-bit. We
do this because the Microsoft toolchain has 32-bit 'long'.

We had updates of certain header files in both Makefile.org and the
Makefile in the directory the header file lived in.  This is error
prone and also sometimes generates slightly different results (usually
just a comment that differs) depending on which way the update was
done.

This removes the file update targets from the top level Makefile, adds
an update: target in all Makefiles and has it depend on the depend: or
local_depend: targets, whichever is appropriate, so we don't get a
double run through the whole file tree.
