Matthias Maennich c92d724e01 abg-cxx-compat: add simplified version of std::optional
In the absence (but desire) of std::optional<T>, add a simplified
version of it to abg_compat:: in case we are compiling with a pre-C++17
standard. Otherwise use std::optional from <optional> directly.

This is being used by a later patch and serves as a prerequisite.
It only serves the purpose of being a compatibility implementation and
does not claim to be complete at all. Just enough for the project's
needs.

	* include/abg-cxx-compat.h (abg_compat::optional): Add new class.
	* tests/tests-cxx-compat.cc: Add new test cases.

This is the Application Binary Interface Generic Analysis and
Instrumentation Library.

It aims at constructing, manipulating, serializing and de-serializing
ABI-relevant artifacts.

The set of artifacts that we are intersted is made of quantities like
types, variable, fonctions and declarations of a given library or
program.  For a given library or program this set of quantities is
called an ABI corpus.

This library aims at (among other things) providing a way to compare
two ABI Corpora (apparently the plural of corpus is copora, heh,
that's cool), provide detailed information about their differences,
and help build tools to infer interesting conclusions about these
differences.
