Optimize glyph row clearing and copying routines.
* dispextern.h (struct glyph_row): Change layout of struct
glyph_row to help copy_row_except_pointers. Adjust comment.
* dispnew.c (null_row): Remove.
(clear_glyph_row): Use offsetof and memset to find and clear
just the members that need clearing. Adjust comment.
(copy_row_except_pointers): Likewise for copying.
