Although I explicitly don't care about the tinfoil-hat reason given in
the initial opening of RT#3628, that "paths usually contain private
information", there *are* situations where it's useful to eliminate the
filenames from the compiled binary.
The two reasons we do care about in the context of firmware such as EDK2
are that it allows for a smaller footprint, and it is also a necessary
component of a binary-reproducible build.
To that end, introduce OPENSSL_FILE and OPENSSL_LINE macros, defining
them to __FILE__ and __LINE__ respectively in the normal case, but to
"" and 0 when OPENSSL_NO_FILENAMES is set.
This is mostly a naïve invocation of
$ sed 's/__\([FL]I[NL]E\)__/OPENSSL_\1/g' -i `git grep -l __LINE__`
but with a few instances change to just print the function name instead
(although those probably need to die anyway) and test cases left untouched.

Depending on user preferences, Configure might get something like

of the argument before a possible equal sign.
For good measure, we lowercase the arguments to be checked in
config.com as well. The original argument is sent on to Configure,

If someone runs a mixed unixmake / unified environment (the unified
build tree would obviously be out of the source tree), the unified
build will pick up on the unixmake crypto/buildinf.h because of
assumptions made around this sort of declaration (found in
crypto/build.info):
DEPENDS[cversion.o]=buildinf.h
The assumption was that if such a header could be found in the source
tree, that was the one to depend on, otherwise it would assume it
should be in the build tree.

The logic to figure out the combinations of --prefix and --openssldir
has stayed in Configure so far, with Unix paths as defaults.
However, since we're making Configure increasingly platform agnostic,
these defaults need to change and adapt to the platform, along with
the logic to combine them.
The easiest to provide for this is to move the logic and the defaults
away from Configure and into the build files.
This also means that the definition of the macros ENGINESDIR and
OPENSSLDIR move away from include/openssl/opensslconf.h and into the
build files.
Makefile.in is adapted accordingly.

With some compilers, C macros are defined differently on the command
line than on Unix. It could be that the flad to define them isn't -D,
it could also be that they need to be grouped together and not be mixed
in with the other compiler flags (that's how it's done on VMS, for
example).
On Unix family platform configurations, we can continue to have macro
definitions mixed in with the rest of the flags, so the changes in
Configurations/*.conf are kept to an absolute minimum.

There were cases where some input was absolute, and concatenating it
to the diretory to the source or build top could fail spectacularly.
Let's check the input first to see if it's absolute.
And while we're on the subject of checking if a file or dir spec is
absolute using file_name_is_absolute() has its own quirks on VMS,
where a logical name is considered absolute under most circumstances.
This is perfectly correct from a VMS point of view, but when parsing
the build.info files, we want single word file or directory names to
only be checked syntactically. A function isabsolute() that does the
right thing is the solution.

This commit provides the basis and core code for an auto initialisation

to remove the need (in many circumstances) to call explicit initialise and

and if non-default initialisation is needed then it will be required.
Similarly for de-initialisation (although this will be a lot easier since
it will bring all de-initialisation into a single function).

It seems realpath() is quite buggy on VMS, or will at least give quite

So we make out own function to get the absolute directory for a given
input, and use rel2abs() or realpath() depending on the platform
Configure runs on.

Some time ago, we had a ex_libs configuration setting that could be
divided into lflags and ex_libs. These got divided in two settings,
lflags and ex_libs, and the former was interpreted to be general
linking flags.
Unfortunately, that conclusion wasn't entirely accurate. Most of
those linking were meant to end up in a very precise position on the
linking command line, just before the spec of libraries the linking
depends on.
Back to the drawing board, we're diving things further, now having
lflags, which are linking flags that aren't depending on command line
position, plib_lflags, which are linking flags that should show up just
before the spec of libraries to depend on, and finally ex_libs, which
is the spec of extra libraries to depend on.
Also, documentation is changed in Configurations/README. This was
previously forgotten.

The "unified" build scheme revolves around small information files,
build.info, which each describe their own bit of everything that needs
to be built, using a mini-language described in Configurations/README.
The information in build.info file contain references to source files
and final result. Object files are not mentioned at all, they are
simply from source files. Because of this, all the *_obj items in
Configurations/*.conf are renamed to *_asm_src and the files listed
in the values are change from object files to their corresponding
source files. For the sake of the other build schemes, Configure
generates corresponding *_obj entries in %target.
Furthermore, the "unified" build scheme supports having a build
directory tree separate from the source directry tree.
All paths in a build.info file is assumed to be relative to its
location, either within the source tree or within the build tree.
