 info of the initial frame.

bitfields where appropriate, remove unused fields.
* window.h (struct window): Remove unused 'last_mark_x' and
'last_mark_y' fields.  Rename 'mini_p' field to 'mini',
change it's type from Lisp_Object to bitfield.
Change type of 'force_start', 'optional_new_start',
'last_had_star', 'update_mode_line' and 'start_at_line_beg'
fields from Lisp_Object to bitfield. Adjust users accordingly.

 src/xdisp.c (pos_visible_p): If the window start position is beyond
 ZV, start the display from buffer beginning.  Prevents assertion
 violation in init_iterator when the minibuffer window is scrolled
 via the scroll bar.

 src/window.c (Fdelete_other_windows_internal): Invalidate the row
