target: use correct target in target-prefixed commands and event handlers
This change contains an alternative to Matthias Welwarsky's #4130
(target-prefixed commands) and to #4293 (event handlers).
get_current_target() must retrieve the target associated to the current
command. If no target associated, the current target of the command
context is used as a fallback.
Many Tcl event handlers work with the current target as if it were
the target issuing the event.
current_target in command_context is a number and has to be converted
to a pointer in every get_current_target() call.
The solution:
- Replace current_target in command_context by a target pointer
- Add another target pointer current_target_override
- get_current_target() returns current_target_override if set, otherwise
current_target
- Save, set and restore current_target_override to the current prefix
in run_command()
- Save, set and restore current_target_override to the event invoking
target in target_handle_event()
While on it use calloc when allocating a new command_context.
