Support frame dimension changes while TTY menus are displayed.

 src/xdisp.c (deep_copy_glyph_row): Handle the case that FROM and TO
 have different dimensions.
 src/dispnew.c (fill_up_frame_row_with_spaces): Now has external
 visibility.
 src/dispextern.h (fill_up_frame_row_with_spaces): Add prototype.

Fixes: debbugs:15575
