Johannes Altmanninger e49c0fb040 unmap: fail if the mapping is currently executing
When unmapping a key sequence that is currently executing, we continue
executing freed memory which can have weird effects.  Let's instead
throw an error if that happens. In future we can support unmap in
this scenario.

Closes #4896

Usage
-----

To test, just type +run [test]+ in the +test+ directory.
It will print each passing test.  If a test fails, a {unified-context-diff}[unified context diff]
is printed showing the tests expected output and the actual output.

Details
-------

+enabled+ is optional.
If it exists and is executable,
it is invoked with no parameters.
If it exits with a non-zero exit code,
the test is assumed to be not applicable to the current environment
(for example, a test for OS-specific integration
isn't useful on a different OS)
and will be silently skipped.

+rc+ is optional
and should contain a sequence of commands,
_e.g._, +set-option+, +define-command+, +declare-option+.
+rc+ is sourced and evaluated before the +cmd+ key sequence is executed.

+in+ is optional
and should contain the initial text loaded into the input buffer
for editing by the +cmd+ key sequence.

+cmd+ is required
and should contain a key sequence that will edit the input buffer.
+cmd+ is executed after the +rc+ command sequence is sourced.

+script+ is optional
and is a shell-script that will be sourced after +cmd+ is executed.
The special +ui_in+ function sends a string
(expected to be a JSON UI message,
see `doc/json_ui.asciidoc` in the Kakoune source)
to the running Kakoune instance,
while the special +ui_out+ function
checks the next JSON UI messages from Kakoune
against its arguments,
and fails the test if any of them are different.

You can also say `ui_out -ignore N` to ignore the next _N_ JSON UI messages,
where _N_ is a positive integer. 

+out+ is optional
and should contain the expected text generated by the +cmd+ key sequence.

If the actual +out+ text
does not match the expected content in the corresponding file,
the unit test will fail.

If there is no +out+
then the unit test will always succeed.

Any +kak_*+ files should match the corresponding expansion
after +cmd+ is complete.
For example, a file named +kak_selection_desc+
should match the +%val{selection_desc}+ expansion.
See `:doc expansions` for a list of available expansions.

If there is an +error+ file,
the test is expected to produce an error.
If Kakoune exits successfully,
or if it fails with the wrong error,
the test is marked as a failure.
