eolian_cxx: initial version of the EFL C++ Bindings Generator.

Summary:
This patch adds 'eolian_cxx' -- a C++ bindings generator --
to the EFL tree. Eolian Cxx uses Eolian API to read .eo files and generate
.eo.hh. It relies/depends on Eo Cxx and Eina Cxx (both non-generated
bindings).

src/bin/eolian_cxx: The eolian_cxx program.
src/lib/eolian_cxx: A header-only library that implements the C++ code
generation that binds the .eo classes.

=Examples=

src/examples/eolian_cxx/eolian_cxx_simple_01.cc: The simplest example,
it just uses some "dummy" generated C++ classes.

src/examples/eolian_cxx/eolian_cxx_inherit_01.cc: Illustrates how
pure C++ classes inherit from .eo generated classes.

src/examples/evas/evas_cxx_rectangle.cc: More realistic example using
the generated bindings Evas Cxx. Still a bit shallow because we don't
have full fledged .eo descriptions yet, but will be improved.

=Important=

The generated code is not supported and not a stable API/ABI. It is
here to gather people interest and get review before we set things in
stone for release 1.11.
