Some keyboards misuse _user functions by defining them in the base files
instead of the corresponding _kb functions (especially led_set_user and
matrix_init_user). Until this is fixed (#5148), I've removed definitions
in my userspace that could cause linking collisions.
* Remove duplicated or unnecessary definitions in config.h and rules.mk
* Use IS_HOST_LED_ON() macro
* Add mouse acceleration to kbd6x:konstantin keymap
* Clear and restore mods when sending macros
* Make SEND_STRING_CLEAN a config option
* Add NO_ACTION_ONESHOT to userspace config
* Add kbd6x:konstantin keymap
* Prevent tap dance from sending LShift as a weak mod in KBD6X
* Move config.h and rules.mk definitions into userspace
* Add UC_WIN to UNICODE_SELECTED_MODES
* Temporarily use Bootmagic until Command is fixed
* Move common behavior from keyboards into userspace
* Update kbd6x:konstantin keymap and userspace
* Make a RCTRL layer in kbd6x:konstantin
* Make KC_ESC turn off layers
* KC_ESC turns L_FN off only if it was locked on
* Add missing record->event.pressed checks
* Move numpad toggling logic into function
* Disable Bootmagic, enable KEYBOARD_SHARED_EP with Command
