- They are obsolete since 2.69, and 2.70 now warn about it
- Bump minimal autoconf to 2.69 (available since 2012)

- And update configure.ac syntax

No need to add the rule to Makefile.am when configure itself can
generate the file.

Add an XDT_VERSION_INIT help macro that will define a set of version
macros using esyscmd so we no lnger need to use configure.ac.in to
perpare the version string for AC_INIT.

XDT_VERSION_INIT(SEMVER, [TAG] will set the following macros:
  - xdt_version
  - xdt_version_major
  - xdt_version_minor
  - xdt_version_micro
  - xdt_version_tag
  - xdt_version_build
  - xdt_debug_default

Example usage:

XDT_VERSION_INIT([4.15.3],[git])
AC_INIT([xfce4-someproject], [xdt_version()])
...
XDT_FEATURE_DEBUG([xdt_debug_default])

- Migrated from the old-csource
- Needed to completely remove exo-csource from exo

- 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

- 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.

* 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.
