  - Glib::KeyfileFlags is now Glib::Keyfile::Flags.
  - Glib::ModuleFlags is now Glib::Module::Flags.
  - Glib::ChecksumType is now Glib::Checksum::Type.
  - Glib::Regex: Move enums inside class.

    use Glib::make_refptr_for_instance() so the std::shared_ptr<> has the
    necessary Deleter.

* SignalProxy:
  connect(): Signals with non-void return values now have no default value
  for the "after" parameter, forcing application developers to think about
  whether they should connect before or after already-connected signal
  handlers, and default signal handlers. This is awkward but necessary.
  Just provide "true" to get the previous behaviour, or use connect_notify().
  connect_notify(): Signals with void return values have no connect_notify(),
  because it is not useful with those signals.

  (Murray Cumming)


2.51.1.1 (unstable):

General:
* Remove no_default_handler in some _WRAP_SIGNAL()s
  This allows application developers to simply override
  the default on_*() signal handlers for these signals too,
  as they can already with most other signals.
  If you are using, for instance, the -Wsuggest-override
  compiler option, watch out for new compiler warnings suggesting
  that your existing signal handler should now be marked with the
  override keyword - that means you should do so but you should
  also stop connecting the signal handler in your code.

2.51.1 (unstable):

This is the first release of the glibmm-2.52 API/ABI.
It installs in parallel with the gtkmm-2.4 API/ABI, of which
the most recent version is glibmm 2.50. We know that is a bit
confusing. We are taking the opportunity to do this glibmm ABI
break while GTK+ (and therefore gtkmm) is also doing an ABI
break. But we cannot call this glibmm-3.0 because there is no
glib 3.0.

Build:
* Require C++14.
  (Murray Cumming)
* Use libsigc++-3.0 instead of libsigc++-2.0.
