close/reload editor tab when file is (re)moved in gui terminal (bug #43922)
* file-editor.cc (handle_file_remove): new code structure
* main-window.cc (construct): connect new signals from octave_qt_link to the
slot handle_file_renamed and the new proxy slot file_remove_proxy;
(file_remove_proxy): proxy calling handle_file_remove but protected by the
mutex of octave_qt_link synchronizing worker and gui thread
* main-window.h: new slot file_remove_proxy
* octave-qt-link.cc (do_file_remove): new method for renaming or removing
files which signals the editor (gui thread) for closing the files before
removing is carried out;
(do_file_renamed): new method for re-loading renamed files into editor;
* octave-qt-link.h: new methods do_file_remove and do_file_renamed,
new signals used in the new methods for signaling the editor slots
* dirfns.cc (rmdir): call the new static octave_link method for removing
a file, which might be opened in the editor before removing a dir;
(rename): call the new static octave_link method for renaming a file,
which might be opened in the editor before renaming it and call the method
for reloading the new renamed file;
* octave-link.h (file_remove): new static method calling purely virtual method
do_file_remove, which is implemented in octave_qt_link;
(file_renamed): new static method calling purely virtual method
do_file_renamed, which is implemented in octave_qt_link
* syscalls.cc (unlink): call the new static octave_link method for removing
a file, which might be opened in the editor before removing it
