Currently, variables cannot contain commands and cannot span more than
one argument. This is due to variable replacement happening after
determining the handler and after splitting the config line into
arguments.
This changes the process to:
0. Check for empty lines and block boundaries
1. Split the arguments as before
2. Verify that the first argument is not a variable. If needed the
following occurs
a. Perform variable replacement on just the first argument
b. Join the arguments back together then split the arguments again. This is needed when the variable
contains the command and arguments for the command.
3. Determine the handler
4. If the handler is cmd_set, escape the variable name so that it does
not get replaced
5. Join the arguments back together, do variable replacement on the full
command, and split the arguments again
6. Perform any needed quote stripping or unescaping on arguments
7. Run the command handler
This allows for config snippets such as:
```
set $super bindsym Mod4
$super+a exec some-command
```
and
```
set $bg bg #ffffff solid_color
output * $bg
```
There's no point having both movement_direction and wlr_direction. This
replaces the former with the latter.
As movement_direction also contained MOVE_PARENT and MOVE_CHILD items,
these are now checked specifically in the focus command and handled in
separate functions, just like the other focus variants.
The previous pull request #2993 tried to fix this by moving the function which
used the layers after the initilization.
Since this initialization is done unconditionally only depending on the struct
definition, move the layer initialization to the beginning of the function.
Also move the signal initialization of the destroy event.
Fixes#2992
input_manager_set_focus is used to set the focus after mapping the view in
view_map. This needs to consider to warp the cursor as well, since for
WARP_CONTAINER, the cursor should warp to the newly created view.
i3 seems to make all window properties, with the exception of
transient_for, optional[1].

It turns out that i3 does not have a `class` key in the json description
of a view, but provides it through `window_properties.class`. Since
`window_properties` has been added by 8fc9328, we can remove `class`
altogether.
