    Eli Zaretskii authored
    Add diagnostic facility for monitoring memory allocated for cache shelving.
     src/xdisp.c (display_line): Release buffer allocated for shelved bidi
     cache.  (Bug#9221)
     src/bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
     amount allocated this far in `bidi_cache_total_alloc'.
     (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
     non-zero, only free the data buffer without restoring the cache
     contents.  All callers changed.
     src/dispextern.h (bidi_unshelve_cache): Update prototype.
     src/xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
     (move_it_in_display_line, move_it_to)
     (move_it_vertically_backward, move_it_by_lines): Replace the call
     to xfree to an equivalent call to bidi_unshelve_cache.
     (move_it_in_display_line_to): Fix logic of returning
     MOVE_POS_MATCH_OR_ZV in the bidi case.
