Add support for attachable/detachable minibuffer
* exwm-workspace.el (exwm-workspace--update-minibuffer-height): Renamed from `exwm-workspace--update-minibuffer' to better reflect its usage. * exwm-input.el (exwm-input--update-focus): Directly put the floating X window at top since the minibuffer is no longer a sibling. * exwm-workspace.el (exwm-workspace--resize-minibuffer-frame): Calculate position in absolute coordinate; put minibuffer at bottom by default; resize the minibuffer frame with ConfigureWindow rather than `set-frame-width'. (exwm-workspace-switch): No need to reparent minibuffer any more. (exwm-workspace--on-ConfigureNotify): Calculate position in absolute coordinate. (exwm-workspace--show-minibuffer, exwm-workspace--hide-minibuffer): Show/Hide the minibuffer by adjusting the stacking order rather than mapping/unmapping. (exwm-workspace--init): Map the minibuffer frame container on creation. * exwm-workspace.el (exwm-workspace--minibuffer-attached-p): New function telling whether the minibuffer is attached. (exwm-workspace--attached-minibuffer-height): New variable storing the height of the attached minibuffer. (exwm-workspace-attach-minibuffer, exwm-workspace-detach-minibuffer): New functions for attaching/detaching the minibuffer. * exwm-workspace.el (exwm-workspace--show-minibuffer): Remove the workaround for minibuffer cursor (seems fixed).
