Fixes: 1267e47de9 ("config/output: Refactor handling of tiered configs")
Output configuration can be applied to a particular output in three
ways: As a wildcard, by connector name and by identifier. This in turn
means that three different configurations must be handled at any given
time.
In the current model, this is managed by merging new configuration into
every other matching configuration. At the same time, an additional
synthetic configuration is made which matchehes both identifier and name
at the same time, further complicating logic.
Instead, manage and store each configuration independently and merge
them in order when retrieving configuration for an output. When changes
are made to a less specific configuration, clear these fields from more
specific configurations to allow the change to take effect regardless of
precedence.

Without this change, i see the following in the sway-ipc manpage:
```
9. GET_CONFIG
MESSAGE
Retrieve the contents of the config that was last loaded
REPLY
An object with a single string property containing the contents of the
config
Example Reply:
{
"config": "set $mod Mod4nbindsym $mod+q exitn"
}
```
apply_output_config_to_outputs uses the specified output config to check
which outputs to apply to, and to use as backup when no config is found.
If any config matches the output, the specified config will be
disregarded.
The only remaining user of apply_output_config_to_outputs is
reset_outputs, which called apply_output_config_to_outputs with either
the first stored wildcard config, or a new empty wildcard config.
Providing a stored or empty wildcard config is practically the same as
calling `apply_all_output_configs`. Replace uses of `reset_outputs` with
`apply_all_output_configs` and remove the now unused functions.
Introduce apply_output_configs, which applies the specified matched
output configs as a single backend commit.
Reimplement apply_output_config_to_outputs using apply_output_configs.
Applying an output config has two stages: Atomic application of
wlr_output_state, and applicaiton of non-atomic state like output
layout.
Split the latter out into finalize_output_config for use in a later
commit.
If we can't create the XKB keymap used for keysym translation,
gracefully error out instead of crashing. This can happen if the
XKB_DEFAULT_LAYOUT is set to an invalid value, for instance.

My code archaeology isn't good enough to determine what this is here
for, but it isn't correct. We should be able to move containers in a
direction without focusing them. AFAICT i3 doesn't do this, so we
shouldn't either.
This fixes ipc commands like move <dir> with criteria that apply to
containers which are not the current focus.
i3 has had this property for over a decade but it wasn't documented
until a couple of years ago, so it was likely missed when developing
sway. Add the property to get us closer to ipc parity with i3.
Check if the app that requested a token has provided a valid input
serial and a focused surface. Downgrade activation request to urgency
otherwise.
This is mostly in line with what other Wayland compositors decided to
do, and offers a better security than the original logic.
We tried to synchronize layer shell popups with the parent layer shell
on commits, but this is subtly wrong because we would only update
the position for one layer shell that was committed, but not any other
layer that might be affected. By moving handling to the scene descriptor
we can iterate all popups and ensure they are synchronized.
