The main goal here is to keep this close to upstream. Changes include: - allow symbols implied by y to become m - make 'imply' obey the direct dependency - allow only 'config', 'comment', and 'if' inside 'choice' - qconf: make search fully work again on split mode - qconf: navigate menus on hyperlinks - remove '---help---' support - qconf: allow to edit "int", "hex", "string" menus in-place - qconf: drop Qt4 support - nconf: fix core dump when searching in empty menu - nconf: stop endless search loops - Create links to main menu items in search - fix segmentation fault in menuconfig search - nconf: Add search jump feature - port qconf to work with Qt6 in addition to Qt5 - fix possible buffer overflow - fix memory leak from range properties Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com>
