Shell is using these, which was revealed by
1bbb5c8107 breaking its build when
generating its introspection due to meta_startup_notification_get_type()
not being found.
We keep the class structs private, so in practice MetaStartupSequence
and MetaBackend can't be derived from (the are semi-private).
Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT
and META_EXPORT_TEST defines to mark a symbols as visible.
The TEST version is meant to be used to flag symbols that are only used
internally by mutter tests, but that should not be considered public API.
This allows us to be more precise in selecting what is exported and what is
not, without the need of a version-script file that would be more complicated
to maintain.

Some types were declared in the public headers so that g-ir-scanner
could resolve the types. This caused warnings when using
-Wredundant-decls, so only redeclare them for the gir scanner.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
Add API to let GNOME Shell have the ability to get notified about remote
access sessions (remote desktop, remote control and screen cast), and
with a way to close them.
This is done by adding an abstraction above the remote desktop and
screen cast session objects, to avoid exposing their objects to outside
of mutter. Doing that would result in external parts holding references
to the objects, complicating their lifetimes. By using separate wrapper
objects, we avoid this issue all together.
Introduce MetaSettings and add the settings managed by MetaBackend into
the new object. These settings include: experimental-features and UI
scaling factor.

The UI scaling depends on whether the framebuffers are scaled. Enable
the caller to determine the what scale its UI should be drawn in, in
relation to the stage coordinate space by calling this function. A new
singal "ui-scaling-factor-changed" is added in order to liston for for
changes.

Implement MetaDnd for emitting DnD signals to plugins such as gnome-shell. The
xdnd handling code comes from gnome-shell, and it is hidden behind MetaDnd now.

This allows creating the stage much earlier than it otherwise would have
been. Our initialization sequence has always been a bit haphazard, with
first the MetaBackend created, then the MetaDisplay, and inside of that,
the MetaScreen and MetaCompositor.
Refactor this out so that the MetaBackend creates the Clutter
stage. Besides the clarity of early initialization, we now have much
easier access to the stage, allowing us to use it for things such as
key focus and beyond.
