Continue work on cursor movement in continued lines.

 xdisp.c (try_cursor_movement): Give up if rows are
 bidi-reordered and point moved backwards.  Examine all the
 candidate rows that occlude point, to return the best match.
 (row_containing_pos): With bidi-reordered rows, don't return the
 first one that occludes point; rather, examine all candidates and
 return the best match, with he glyph that's closest to point.
 (display_line): When looking for min position, don't consider
 negative values of glyph->charpos.  (Fixes a crash with "C-x 3" at
 ZV.)  Record the position after EOL in it->eol_pos, and use it to
 set end_pos of the last row produced for a continued line.  Fix
 the condition for passing candidate rows to set_cursor_from_row:
 check ends_at_zv_p flag of the best candidate row, not of the
 current row.
 dispextern.h (struct it): New member eol_pos.
 .gdbinit (prowlims): Display the ends_at_zv_p flag.
