Commit: Chris Feng <address@hidden>

    Add support for keyboard macro
    
    * exwm-core.el (exwm--kmacro-map): New keymap used when executing
    keyboard macros.
    (exwm-mode): Use `exwm--kmacro-map' to override the default keymap.
    * exwm-input.el (exwm-input--on-KeyPress-line-mode): Send extra key
    events when defining keyboard macros.
