New internal-border face and args for select-window and x-focus-frame

Add `internal-border' face and handle it whenever clearing the
internal border.  If NORECORD equals the symbol
'mark-for-redisplay', `select-window' will not record the window
but still mark it for redisplay.  The new argument NOACTIVATE
for `x-focus-frame' tries to not activate FRAME when set.
