6321e7c5aa Add needs_composition APIs 
Right now, compositors are expected to query liftoff_layer_get_plane_id to
decide whether a layer needs to be composited.

However there are cases where a layer has no plane, but still doesn't need
composition (e.g. when FB_ID is zero or when alpha is zero, in the future when
the layer is out of CRTC bounds etc).

Add a new API to make users' life simpler.

Closes: https://github.com/emersion/libliftoff/issues/54

61fd4c099a Make liftoff_output_apply return an int 
Callers may want to get more details about the failure, in
particular EPERM indicates that the user isn't DRM master (can
happen on VT switch).

b08bbaa5e6 Split liftoff_log_init into set_handler and set_priority 
This allows callers to change only one of those, without the other.
Also rename importance to priority and func to handler.

88eb35b084 build: remove libraries keyword arg from pkgconfig.generate 
This fixes the following warning:

    ../subprojects/libliftoff/meson.build:53: DEPRECATION: Library liftoff was
    passed to the "libraries" keyword argument of a previous call to generate()
    method instead of first positional argument. Adding liftoff to "Requires"
    field, but this is a deprecated behaviour that will change in a future
    version of Meson. Please report the issue if this warning cannot be avoided
    in your case.

Remove DRM_MODE_PAGE_FLIP_EVENT from commit flags 
It's illegal to request a page-flip event when performing a test-only commit.
The kernel returns EINVAL in this case [1].

Allow caller to pass commit flags 
When the caller wants to perform a modeset, they will need to pass
DRM_MODE_ATOMIC_ALLOW_MODESET in the atomic commit flags, otherwise the driver
will fail the commit. libliftoff also needs to provide these flags in its
test-only commits.
