Fix libdir path on darwin

In current Configure script, libdir can be specified either an absolute
path or relative, while in Configurations/shared-info.pl, on darwin
system "-install_name" only accepts relative libdir path, and the
program fails when receiving absolute libdir path. This PR is to fix
this and match requirements of scripts.

Configuration: Make it possible to have an argument file

Some compilers / linkers allow arguments to be given in a file instead
of on the command line. We make it possible to specify this by giving
the compiler / linker flag for it, using the config attribute
'shared_argfileflag'.

This currently only impacts the build of shared libraries, as those
are potentially made up of a massive amount of object files, which has
been reported to overwhelm the command line on some platforms.

Fixes #12797

Use the inherited 'bsd-gcc-shared' config on 32-bit x86 BSDs.

BSD-generic32 already uses this for building shared libraries on other
32-bit BSD platforms. Commit b7efa56 collapsed various *BSD targets
down to the BSD-generic ones and BSD-x86. At the time only
OpenBSD/i386 used `bsd-shared` while both FreeBSD and NetBSD used
`bsd-gcc-shared`. In practice, all of the BSDs are using either a
GCC/ld.bfd toolchain or a clang/lld toolchain both of which are
compatible with 'bsd-gcc-shared'.

Retire 'bsd-shared' since this removes the last user.

Fixes #12050.

Configuration: make Solaris builds with gcc recognise GNU ld

The solaris config targets assumed that GNU cc used Sun ld at all
times. However, there are setups where GNU ld is used instead, so we
adapt the Solaris gcc config targets to use the mechanism introduced
with Configurations/shared_info.pl to try to detect what ld flavor is
being used and set the diverse ld flags accordingly.

Don't use '-z defs' if sanitizers are used

There are quite a number of sanitizers for clang that aren't

to be selective about what sanitizers to look at to determine if
'-z defs' should be used of not.

Under these circumstances, the sane thing to do is to just look for
any sanitizer specification and not use '-z defs' if there's one
present.

Don't use '-z defs' with Clang's sanitizers

The clang documentation in all sanitizers we currently use says this:

When linking shared libraries, the {flavor}Sanitizer run-time is
not linked, so -Wl,-z,defs may cause link errors (don’t use it
with {flavor}Sanitizer)

(in our case, {flavor} is one of Address, Memory, or UndefinedBehavior)

Therefore, we turn off that particular flag specifically when using
the sanitizers.

Refactor linker script generation

The generation of linker scripts was badly balanced, as all sorts of
platform dependent stuff went into the top build.info, when that part
should really be made as simply and generic as possible.

Therefore, we move a lot of the "magic" to the build files templates,
since they are the place for platform dependent things. What remains
is to parametrize just enough in the build.info file to generate the
linker scripts correctly for each associated library.

"linker script" is a term usually reserved for certain Unix linkers.
However, we only use them to say what symbols should be exported, so
we use the term loosely for all platforms. The internal extension is
'.ld', and is changed by the build file templates as appropriate for
each target platform.

Note that this adds extra meaning to the value of the shared_target
attribute.

Make "make variables" config attributes for overridable flags

With the support of "make variables" comes the possibility for the
user to override them. However, we need to make a difference between
defaults that we use (and that should be overridable by the user) and
flags that are crucial for building OpenSSL (should not be
overridable).

Typically, overridable flags are those setting optimization levels,
warnings levels, that kind of thing, while non-overridable flags are,
for example, macros that indicate aspects of how the config target
should be treated, such as L_ENDIAN and B_ENDIAN.

We do that differentiation by allowing upper case attributes in the
config targets, named exactly like the "make variables" we support,
and reserving the lower case attributes for non-overridable project
flags.

Configure et al: rename all dso_* to module_* in shared-info.pl

Because there are already attributes with the dso_ prefix that are
used instead of the corresponding lib_ attributes rather than in
addition to them, it gets confusing to have similar or exactly the
same attributes working with different semantics on Unix.

So we rename those by changing the prefix dso_ to module_, and having
those work just like the shared_ attributes, but for DSOs.

Configure: Read in extra information to help create shared libraries

This will replace the use of Makefile.shared

This also means a small adjustment on how the attributes dso_cflags,
dso_cxxflags and dso_lflags are treated. They were previously treated
as an extension to shared_cflag, shared_cxxflag and shared_ldflag, but
they should really be regarded as alternatives instead, for example
for darwin, where -dynamiclib is used for shared libraries and -bundle
for DSOs.

We take the opportunity to clean out things that are redundant or
otherwise superfluous (for example the check of GNU ld on platforms
where it never existed).
