We store both queued and current buffers to be able to retain both the
framebuffer currently on screen and the one queued to replace it. From a
re-use perspective, we only care about the last committed framebuffer.
The viewport is only stored in order to be re-used together with the
last committed framebuffer, so do away with the queued/current
distinction and store a single viewport updated every time a commit
completes.
Instead of trying to restore the drm state when the session is activated
again, just disconnect all outputs when the session is deactivated. The
scan that triggers on session activation will rediscover the connectors.
Accessing the output state viewport require a buffer, and that might not
have a state with a buffer when preparing the plane properties for an
atomic commit.
Instead, store the properties at the same time as the fb, and use a
similar mechanism to carry the state around.
This commit fixes the following interaction:
1) The host compositor sends a configure sequence for an output.
2) Before handling it, the guest compositor disables and immediately
re-enables the output.
3) The guest compositor tries to ack the configure event from step 1
which isn't relevant anymore after unmapping and re-initialization.
Instead, ignore all configure events after unmapping until we're sure
the host compositor has processed the unmapping.

- Reset all variables representing an initialized xdg_toplevel's state
on unmap.
- Send an initial commit only when an output is about to be enabled.
- If an output isn't configured yet, don't commit a buffer.
This centralizes logic common for both the atomic and libliftoff
backends. Additionally, a struct will make it easier to implement
multi-connector commits (since it can be stored in an array).
Use the same logic for cursor FBs as we currently use for primary
FBs. This also fixes the same bug as [1] but in a different, more
robust way.
The new logic integrates better with atomic and will be required
anyways in the future when set_cursor will be superseded by a better
API.

On startup, we fetch the previous MODE_ID blob ID so that
compositors can keep using the previous mode if they want to.
However, that blob doesn't belong to us, it belongs to the
previous DRM master. As a result, we get an error when trying to
destroy it.
Fix this by tracking whether the blob belongs to us or not.

wlr_output.refresh is populated by core wlr_output, and thus will
be zero for a custom mode with an unset refresh rate.
Save the refresh rate from the drmModeModeInfo in wlr_drm_connector
instead.
