- This way, we don't need to provide a README file, now that we start to
  switch to README.md for markdown readme on gitlab
- "[..] differences between the gnu and foreign flavours is
  that the former requires the presence of a number of files in the
top-level of the projects": https://autotools.io/automake/options.html
- It also stop warning when using GNU make syntax, but we already
  mandate gnu make, so it's not a problem

- xdt-csource will replace exo-csource (projects using exo-csource needs to be updated)
- The work started in issue #6449 but the full migration has never been done.
- This way, we do not need to check for exo even when exo is not
required.

- Also simplify a bit the XDT_AUTOGEN_REQUIRED_VERSION detection
- Remove the check of the unused doc submodule

- Remove useless macros: m4macros/xdt-python.m4 and m4macros/xdt-xfce.m4
are not used
- Update URLs
- Remove xdt-commit, used to generate Changelog, now done via make
distcheck

Other projects define this too; in previous versions it was simply ignored
because $Id$ was only generated by SVN checkout.

Commit de3d7f02 "Display warning if AC_PROG_INTLTOOL is used (bug #8930)"
prints a warning with a hardcoded libtool version. This patch replaces
the hardcoded value with the version number defined in configure.ac.in,
so developers will use the proper requirements.

xfce-mcs-manager has long been archived and replaced by xfconf.

This check is only for old panels (<=4.1.90) and useless today.

* automake-1.11
* autoconf-2.60
* libtool-2.4
* glib-2.30
* xfce4-panel-4.9

Update copyright dates, remove subversion $id strings, update .gitignore.

Depending on files generated during build via $(srcdir) breaks builds
that take place outside the source directory. This commit fixes one such
mistake in scripts/Makefile.am that refers to $(srcdir)/xdt-autogen.in.

Similar to AC_PROG_LIBTOOL, which has been replaced with LT_PREREQ
and LT_INIT, AC_PROG_INTLTOOL has been replaced with IT_PROG_INTLTOOL.
This commit makes xdt-autogen recommend intltool >= 0.35.0 and displays
a warning if AC_PROG_INTLTOOL is still being used in a configure script
template.
