Make the processing of build.info files more aware of absolute dirs

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.

Provide framework for auto initialise/deinitialise of the library

This commit provides the basis and core code for an auto initialisation
and deinitialisation framework for libcrypto and libssl. The intention is
to remove the need (in many circumstances) to call explicit initialise and
deinitialise functions. Explicit initialisation will still be an option,
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).

Use rel2abs() on VMS, rather than realpath()

It seems realpath() is quite buggy on VMS, or will at least give quite
surprising results. On the other hand, realpath() is the better on
Unix to clean out clutter like foo/../bar on Unix.

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.

unified build scheme: add and document the "unified" driving engine

common.tmpl will be used together with the template build file, and is
the engine that connects the information gathered from all the
build.info files with making the build file itself.

This file expects there to be a template section in the build file
template that defines a number perl functions designed to return
strings with appropriate lines for the build system at hand. The
exact functions, what they can expect as arguments and what output
they're expected to produce is documented in Configurations/README.

Enhance and clear the support of linker flags

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.

unified build scheme: a first introduction

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.
