Since it takes some time for EXWM to create a buffer for a window (to do some
checking for example), the window may send several MapRequest events before
it's mapped. This commit should fix such issue.
* Fix `exwm-reset`
* Make input mode buffer local
* Allow window to stay in `char-mode` while setting input focus to other window
or switching to other workspace
* Correct ConfigureNotify events sent to fullscreen windows.
* Exit fullscreen mode before switching workspace.
* Temporarily treat `xcb:Atom:_NET_WM_STATE_ABOVE` as
`xcb:Atom:_NET_WM_STATE_FULLSCREEN` since
a) "plugin-container" (Flash Player) seems only set this, and
b) it's not normally used by applications.
This makes fullscreen videos working in e.g. iceweasel.
* Prevent marking the end of a key sequence with a single `C-u'.
* Enable `C-u' prefix for key simulation since it's not possible for users to
define simulation keys starting with `C-u'.
* Make Emacs idle only after the visual parts are updated to prevent from
disturbing users.
* Should use '?\s' instead of '? '.
