  signal: Add connect_first()

  Add connect_first(const slot_base&) and connect_first(slot_base&&)
  in internal::signal_impl, signal_base, signal_with_accumulator and
  trackable_signal_with_accumulator.
  Replace some calls to connect() by connect_first() in test_signal
  and test_scoped_connection.

  Visual Studio builds: Convert build docs to MarkDown

  Convert the README.txt to MarkDown format so that it is easier on the eye in

  * Some other minor tweaks

  sigc++.pc.in: Set -DLIBSIGCXX_STATIC in cxxflags as needed

  Update the Meson build files to put in -DLIBSIGCXX_STATIC when we are building
  a static build of libsigc++.
  
  For the CMake and autotools build, this is not used.

  build: Actually support MSVC static builds

  Apply -DLIBSIGCXX_STATIC as appropriate when we request a static build to be
  done for the Meson and NMake builds, and skip building the version .rc file
  if a static build is requested.
  
  For the NMake builds, separate the build artifacts from the static and shared
  builds.
  
  The CMake builds are not updated here as it always assumes a shared build, nor
  are the autotools builds since it is not used for Visual Studio builds at all.

  meson: Disallow default_library == 'both' on Visual Studio

  We need different defines/cflags for building static and shared builds of
  libsigc++, so we can't really support default_library = 'both' for libsigc++
  without much retinkering.
  
  So, just disallow such builds at least for now.
  
  Also, save up whether we are attempting a static build in the Visual Studio
  build.

  Allow slots with rvalue reference parameters

  In code based on Glibmm it's quite common to convert a Glib C structure
  to a Glib::Object's descendant before passing it as a parameter to a
  slot. If the slot is not supposed to modify the object, then everything
  is fine, we can declare the parameter as a const reference and the
  temporary object will be accurately dealt with by the compiler. However,
  if the Glib based object is getting modified, the only way to pass it to
  the slot is to declare it a Glib::RefPtr shared pointer. This creates a
  lot of unnecessary churn of memory allocations for a simple deal of
  calling a signal. However, C++ has a specific mean for this particular
  semantic of passing a temporary object: rvalue reference.
  
  For example, somewhere inside Gtkmm might be a declaration:
  _WRAP_SIGNAL(void sun_rose(const Glib::RefPtr<Gtk::Sun> &new_sun),
  "sun-rose")
  
  Instead its more semantically correct to write:
  _WRAP_SIGNAL(void sun_rose(Gtk::Sun &&new_sun), "sun-rose")
  
  And later somewhere in your code:
  world->signal_sun_rose().connect([&](auto &&new_sun) {
    new_sun.shine();
  });
  
  This commit makes a couple of simple modifications that allow declaring
  signals and slots with rvalue reference parameter.

  NMake Makefiles: Use Meson-style DLL and .lib naming if requested

  To make things more consistent and less prone to confusion, if 'USE_MESON_LIBS'
  is specified in the NMake command line, build the DLLs and .lib's that are
  named like the Meson counterparts.  Binaries built with Meson+Visual Studio
  and the ones that are built via NMake using 'USE_MESON_LIBS' are
  interchangeable.

  won't be updated in the html files when they are installed.
  * docs/docs/reference/Doxyfile.in: Remove PERL_PATH and MSCGEN_PATH.

  NMake Makefiles: Use toolset version in DLL filename by default

  The libsigc++ DLL and .lib was only named 'sigc-vc150(d)-3_0' until the
  previous patches in this series improved Visual Studio 2019 support to
  name the DLL and .lib by using 'sigc-vc160(d)-3_0'.
  
  This updates the naming of the DLL and .lib to the toolset version as
  defined by Microsoft by default, i.e. 'vc141' for Visual Studio 2017
  and 'vc142' for Visual Studio 2019.  If the former DLL naming ('vc150')
  is desired, passing 'USE_COMPAT_LIBS=1' will achive this.

  Rework NMake Makefiles

  Clean up the NMake Makefiles so that they will become easier to maintain and

  * Rename instances of 'libsigcpp' to 'sigc'
  * Just use 'md' directly to create all intermediate directories
  * "Generate" the rules to build the example and test programs, instead of using
    generic hand-written rules for all of them, as most of them share common
    rules.
  * Add a 'prep-git-build' rule to allow building directly from a GIT checkout

  that are now in untracked/MSVC_NMake, when a release tarball is

  meson/Windows: Fix builds when builddir is a subdir of source tree

  It appears that Meson did not construct the paths properly for
  shutil.copy2() when building in a build directory that is a
  subdirectory of the sources, when using meson.current_build_dir(),
  possibly due how path separators are handled.
  
  Fix this by constructing the paths using project_build_root / 'MSVC_NMake'.

2019-12-29  Chun-wei Fan  <fanchunwei@src.gnome.org>

  meson.build: Fix 'meson dist' on Windows

  Since we are assured that we are using Python 3.x on when we run Meson, we
  do not really need to look for the 'python3' executable, but we could
  just use whatever Python interpreter that is used to run Meson.
  
  This will fix situations where it is commonly the case where we may have
  multiple Python 3.x installations on Windows (www.python.org, and those
  from Cygwin/mingw-w64), so that Meson really uses one and only one
  Python installation to run everything that is Python-related, which will
  thus fix '[meson|ninja] dist' on Visual Studio builds.

  test_limit_reference: Avoid virtual-move-assign warning

  "= delete" Bases's move operations because the defaulted one

  This avoids this compiler warning, at least with g++ 9.2:
  
  test_limit_reference.cc:12:7: error: defaulted move assignment for ‘{anonymous}::Base’ calls a non-trivial move assignment operator for virtual base ‘sigc::trackable’ [-Werror=virtual-move-assign]
     12 | class Base : virtual public sigc::trackable
        |       ^~~~
  test_limit_reference.cc:22:7: error: defaulted move assignment for ‘{anonymous}::Derived’ calls a non-trivial move assignment operator for virtual base ‘{anonymous}::Base’ [-Werror=virtual-move-assign]
