  https://github.com/cgmb/guardonce
* Add missing G_BEGIN_DECLS/G_END_DECLS pairs.
* Add missing G_GNUC_CONST annotation for get_type() functions.
* Have a LICENSES directory, to better follow the REUSE way of applying

  add GtkSourceIconv and GtkSourceInputStream (new classes).
- Rework GtkSourceEncoding.
- Start to rework GtkSourceFile.
- Rework GtkSourceFileLoader (modernize the code and use GtkSourceInputStream

- Some small changes/improvements to the 'list-langs' and 'uncrustify' tools.

Other:
- Improve the documentation for contributors. Start to write a list of possible
  tasks in the “docs/possible-tasks/” directory.
- Build system: tune the CFLAGS in order to run code-coverage tools
  conveniently.
- Get rid of HAVE_CONFIG_H (Autotoolism).
- Move some typedefs to their corresponding classes.
- License headers for *.c and *h files: follow REUSE way of applying licenses.
