9e8d32980a meta: Move enum definitions to meta-enums.h
Commit bf84b24 created meta-enums.h but it's pretty empty so far, the
vast majority of enum definitions is still in common.h.

Move the Meta enum definitions to meta-enums.h as one would expect them
to be found.

8b9341131a context: Add a new API to raise and restore NOFILE limits
Wayland, especially when using SHM buffers, can use a lot of file
descriptors and can possibly reach the NOFILE soft limit.

Add a new API to MetaContext to raise and restore the NOFILE limit so
that the Wayland compositor can use as many file descriptors as the hard
limit allows.

e62f7e2910 context: Allow controlled destruction
Add a method meta_context_destroy() that both runs dispose and unrefs
the context. Tear down is moved to dispose() so that things owned by the
context are destroyed when calling meta_context_destroy(), or when the
last reference is released.

68b376a944 context: Make context owner of MetaDisplay
It may still be closed from elsewhere, e.g. when being replaced, but the
reference is owned by MetaContext instead of itself.

b1c643eeaa context: Make the context owner of the backend
There is still the `_backend` singleton still, as there are still the
`meta_get_backend()` that needs to work for now.

aa306ac3ca Introduce MetaContextMain
This object intends to replace the scattered functions that are used to
make up what is effectively a "mutter context". It takes care of the
command line arguments that is now done in main.c, persistant virtual
monitors, and the like.

e09de6787f context: Handle dealing with option entries
Users can add option entries, and it'll be part of the configuration
phase.

Create the main group manually to be able to set a user_data pointer;
this will be required to not have to rely on globals when parsing
options using a callback.

2e784e23a2 context: Add 'notify_ready()' vfunc and method
This intends to replace the call to `meta_register_with_session()` that
deals with X11 session management, and is called when the user is
"ready". In thet test context, doing that makes no sense, so make it a
no-op.

02176eab83 context: Add start/run/terminate phases
The start phase creates the MetaDisplay object, and initializes Wayland, and
creates the main loop.

The run phase runs the main loop and handles returning an error if the
context was terminated with an error.

The terminate phase terminates the main loop, with or without an error.

75f9085ab9 context: Add setup phase
During this phase, the backend is created and configured. Currently only
configured, but will gain more logic that currently main.c does with
various helpers.

6c6b5b9a48 context: Add entry points for context configuration
Configuration is the first step of the lifetime of a context, after
creation; it's here where argc/argv is processed, and it's determined
what kind of compositor, etc, it is going to be.

The tests always run as Wayand compositors, so the configuration is
quite simple, but will involve more steps later on.

e020fdfddf Introduce mostly empty MetaContext type
This type is intended to replace the scattered functions used to
configure how the Mutter compositor is run. It currently doesn't do
anything, and only has a human readable name, intended to be set to e.g.
"GNOME Shell".

It's an abstract type, and is intended to be used via either a future
`MetaContextMain` for real display server use cases, and a
`MetaContextTest` for test cases.
