Do not copy X event in handle_one_xevent except KeyPress case. 

Wnen XEvent is processed, it is unlikely to be changed except
KeyPress case, so we can avoid copying and use const pointer to
const data to make sure that an event is not changed elsewhere.
* xterm.c (handle_one_xevent): Change 2nd arg to 'const XEvent *
const' and do not create local copy except for the KeyPress event.
Use casts to avoid a few glitches.  Adjust formatting.  Add comments.
(SET_SAVED_BUTTON_EVENT): Remove and move the code to the only user.
