Make Configure recognise -rpath and -R to support user added rpaths
for OSF1 and Solaris.  For convenience, add a variable LIBRPATH in the
Unix Makefile, which the users can use as follows:

    ./config [options] -Wl,-rpath,\$(LIBRPATH)

In an earlier attempt to simplify the processing of disabled options,
'no-err' and 'no-async' stopped working properly.  'err' and 'async'
are directories under 'crypto/', but they are special insofar that
they can't be simply skipped, like all the algorithm directories can,
so they need special treatment among the disablable things.

Traditionally Configure passed $ENV{PERL} to Makefile. But this
resulted in ambiguilty as Configure script could be executed by
interpreter different from one executing remaining scripts. Since
we separate compile- and run-time interpreters with HASHBANGPERL
variable, there is no reason to segment the build procedure.

The background story is that util/shlib_wrap.sh was setting LD_PRELOAD
or similar platform dependent variables, just in case the shared
libraries were built with -rpath.  Unfortunately, this doesn't work
too well with asan, msan or ubsan.

So, the solution is to forbid the combination of shared libraries,
-rpath and any of the sanity analyzers we can configure.

This changes util/shlib_wrap.sh so it only contains the code that sets
LD_PRELOAD when -rpath has been used when configuring.

Build file templates would be looked up like this if the user gave us
an additional directory to look for configuration files and build file
templates:

    $OPENSSL_LOCAL_CONFIG_DIR/$OSTYPE-Makefile.tmpl
    $SOURCEDIR/Configurations/$OSTYPE-Makefile.tmpl
    $OPENSSL_LOCAL_CONFIG_DIR/Makefile.tmpl
    $SOURCEDIR/Configurations/Makefile.tmpl

So for example, if the user created his own Makefile.tmpl and tried to
use it with a unixly config, it would never be user because we have a
unix-Makefile.tmpl in our Configurations directory.  This is clearly
wrong, and this change makes it look in this order instead:

    $OPENSSL_LOCAL_CONFIG_DIR/$OSTYPE-Makefile.tmpl
    $OPENSSL_LOCAL_CONFIG_DIR/Makefile.tmpl
    $SOURCEDIR/Configurations/$OSTYPE-Makefile.tmpl

The definition of STITCHED_CALL relies on OPENSSL_NO_ASM.  However,
when a configuration simply lacks the assembler implementation for RC4
(which is where we have implemented the stitched call), OPENSSL_NO_ASM
isn't implemented.  Better, then, to rely on specific macros that
indicated that RC4 (and MD5) are implemented in assembler.

For this to work properly, we must also make sure Configure adds the
definition of RC4_ASM among the C flags.

PROGRAM_NO_INST, ENGINES_NO_INST, SCRIPTS_NO_INST and LIBS_NO_INST are
to be used to specify program, engines, scripts and libraries that are
not to be installed in the system.  Fuzzers, test programs, that sort
of things are of the _NO_INST type, for example.

For the benefit of build file templates and other templates that use
data from configdata.pm, a new hash table $unified_info{install} is
created.  It contains a set of subhashes, one for each type of
installable, each having an array of file names as values.  For
example, it can look like this:

    "install" =>
        {
            "engines" =>
                [

INCLUDE statements in build.info files were source tree centric.  That
meant that to get include directory specs in the build tree, we had to
resort to perl fragments that specified the build tree include paths
as absolute ones.

This change has the INCLUDE statement consider both the source and
build tree for any include directory.  It means that there may be some
extra unnecessary include paths, but it also makes life simpler for
anyone who makes changes in the build.info files.
