janitorial: clean up tree in preparation for libpeas-2.0

This starts the process of working towards a new Libpeas 2.0 ABI. The
goals of this ABI break are:

 * Modernize and cleanup GObject usage within libpeas
 * Use GObject's in more places to allow for better GIO integration
 * Implement GListModel where it makes sense
 * Remove GTK 3 and GTK-based APIs as those are trivial to implement in
   applications with GTK 4 and newer.
 * Drop Python 2 support
 * Simplify support for new plugin loaders

-Overview of Changes in libpeas 1.36.0
-=====================================
+# Libpeas 1.99.0
 
-* PeasExtensionSet now implements GListModel
-* libpeas now requires GLib 2.44 or newer for GListModel
-* Translation updates:
-  - Interlingue
-  - Turkish
+This is the beginning of the libpeas 2.0 series. It breaks ABI with previous
+versions of libpeas and therefore can be installed along-side libpeas-1.0.
 
-As a note to packagers, we'd like to mention that there is an intention to
-release a new libpeas-2 ABI for GNOME 45 to fix a number of longstanding
-needs which can only be resolved with an ABI break.
+This allows libpeas to improve API ergonomics as well as implement features
+which will improve integration with GTK 4.
 
-Overview of Changes in libpeas 1.34.0
-=====================================
+## Removals
 
-* Resource-based plugins are sorted by module-name before loading
-  to aid in reproducibility.
-* Sorting of plugins with dependencies has been altered to improve
-  sort-order with more complex plugin dependency graphs.
-* Translation updates:
-  - Hebrew
-  - Georgian
-  - Bulgarian
