Make data types more C-like

Add a new `CKeyActionResult` that uses a `char *` instead of an
`Option<CString>`. Make our `c_run_key_action()` return this type
instead of `KeyActionResult`. Include some code to handle the
translation between the two types.

Names for now are just temporary so I can get something working. We'll
re-think proper names once I've tested this manually and have something
somewhat working.
