If the noop output is focused (all other outputs disabled/disconnected),
do not auto assign a layer surface to it. The noop output is not enabled
and does not have the `output->layers` list initialized. It also does
not make sense to map the layer surfaces to something that is not
visible.

Fixes#3759
This makes it so running `move [to] scratchpad` on a container already
in the scratchpad does not return an error. To match i3's behavior, a
visible scratchpad container will be hidden and a hidden scratchpad
container will be treated as a noop.
This modifies the places where output_get_active_workspace is called to
handle a NULL result. Some places already handled it and did not need a
change, some just have guard off code blocks, others return errors, and
some have sway_asserts since the case should never happen. A lot of this
is probably just safety precautions since they probably will never be
called when `output_get_active_workspace` is not fully configured with a
workspace.
If an output's node was dirty and the transaction was committed before a
workspace was moved to or created for the output, the instruction would
have a bad value for `state->active_workspace` due to a missing
length check in `output_get_active_workspace`. If there was no focus on
the output, the first workspace was being returned. If the workspace
list was currently empty, the value was either garbage, or in the case of
an output being disabled and re-enabled, a workspace that may have been
previously freed. This just adds the length check to avoid returning out
of bounds value.

This calls `workspace_consider_destroy` on the workspace that was
visible on an output that a workspace was just evacuated to. This
prevents having hidden empty workspaces.
This changes `workspace_next_name` to use the next available number as
the workspace name instead of the number of outputs. This fixes the case
where a number that is already in use could be returned. The workspace
numbers in use have no relation to the number of outputs so it makes
more sense to use the lowest available number
This documents the wildcard character for both inputs and seats. There
is also a tip added on trying the wildcard to verify a setting if the
identifier does not appear to be working.
This fixes the issue of the display freezing on reload with
wlroots#1545.
On master, all output configs are applied on reload. This may cause an
output to have its config applied up to three times, instead of just
once. The three cases are: output name, output identifier, and wildcard.
Not only is this inefficient, but it can cause swaybg to be spawned and
immediately killed.
However, swaybg requires two roundtrips of wl_display (to obtain needed
globals) before it enters its normal event loop. Modesetting will
roundtrip the wl_display. Without modesetting, waitpid for killing
swaybg could block infinitely due to swaybg being blocked by
wl_display_roundtrip.
This only configured an output once. It either uses the wildcard config
or creates an empty wildcard config and applies that. This also fixes a
bug where an output would not be reset when there is no output config to
apply to it.
