meson.build: Specify 'check' option in run_command()
The default value will be changed in future Meson releases.
Don't use deprecated python3.path() and execute(..., gui_app: ...).

docs/docs/reference/Doxyfile.in: Remove obsolete entry

tools/tutorial-custom-cmd.py: Add comment about used stylesheet

CI: Install docbook-xsl where documentation is built
If docbook-xsl is installed, the xsltproc command reads stylesheets
from local files instead of from http://docbook.sourceforge.net.
Faster and safer. Reading from docbook.sourceforge.net sometimes fails.
Remove test with g++-7.

docs: Fix links to sigc::slot and sigc::signal
Doxygen creates links to sigc::slot and sigc::signal only if
template parameters are included in the documentation.
sigc::slot<T_return(T_arg...)>, sigc::signal<T_return(T_arg...)>.

ptr_fun(), mem_fun() docs: Remove left-overs from sigc++-2.0
Some documentation of template parameters described sigc++-2.0
rather than sigc++-3.0.

Reformat to suit clang-format-12
2021-12-26 Kjell Ahlstedt <kjellahlstedt@gmail.com>
CI: Use clang-format-12
and call clang-format directly without using autogen.sh + make.
2021-12-23 Kjell Ahlstedt <kjellahlstedt@gmail.com>
Second attempt to suit clang-format 10
Irritating that different versions of clang-format don't agree on what's
an acceptable format, and that clang-format 10 is not easily installable
on Ubuntu 21.10.
2021-12-23 Kjell Ahlstedt <kjellahlstedt@gmail.com>
Format source code to suit clang-format
* sigc++/functors/mem_fun.h:
* sigc++/functors/ptr_fun.h:
* tests/test_rvalue_ref.cc: Reformated with clang-format 13,
but CI uses clang-format 10.
Also add #include <utility> where std::forward was added. Doesn't seem
to be necessary with g++ or clang++. Mostly a precaution.

Add missing perfect forwarding in mem_functor and pointer_functor
This is a missed addition to the commit that allowed rvalue references
in slot parameters.
2021-12-23 Slava Andrejev <vyac.andrejev@gmail.com>
Add missing perfect forwarding in bound_mem_functor::operator()
This is a missed addition to the commit that allowed rvalue references
in slot parameters.

meson.build: Check if Perl is required for building documentation
New versions of mm-common use the Python scripts doc_postprocess.py
and doc_install.py instead of the Perl scripts doc-postprocess.pl and
doc-install.pl when documentation is built.

docs: Remove some obsolete files
Remove docs/docs/manual/README, docs/docs/reference/README
and docs/Makefile.

docs/docs/manual: Add some formatting when html files are generated
making it slightly more similar to gtkmm-documentation and libxml++.
In Autotools builds, don't distribute the empty manual/README file.

test_rvalue_ref: Small fixes
* tests/.gitignore:
* tests/CMakeLists.txt:

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.
