  [cache] Notice if a cache query induced the node list change.
  
  Some node comparators (comparing the cache node content and
  the properties specified by the query) can flush the cache
  node to prevent the cache inflation.  The change may
  invalidate the pointers to the node obtained before the node
  comparison, so the change should be noticed to the caller.
  The problem caused by the cache node changing is reported by
  Harsha, see Savannah bug #31923.
  
  * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new
  argument `FT_Bool* list_changed' to indicate the change of
  the cached nodes to the caller.
  (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes
  by `_list_changed'.
  (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
  and update it when FTC_Manager_FlushN() flushes any nodes.
  
  * src/cache/ftccback.h (ftc_snode_compare): Updated to fit
  with new FTC_Node_CompareFunc type.  (ftc_gnode_compare): Ditto.
  
  * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to
  use TRUE/FALSE macros.  (ftc_basic_gnode_compare_faceid):
  New argument `FT_Bool* list_changed' to indicate the change
  of the cache nodes, anyway, it is always FALSE.
  
  * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to
  use TRUE/FALSE macros.  (ftc_cmap_node_compare):
  New argument `FT_Bool* list_changed' to indicate the change
  of the cache nodes, anyway, it is always FALSE.
  (ftc_cmap_node_remove_faceid): Ditto.
  
  * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL
  pointer to FTC_CACHE_TRYLOOP_END(), because the result is
  not needed.  (FTC_Cache_Lookup): Watch the change of the cache
  nodes by `list_changed'.  (FTC_Cache_RemoveFaceID): Ditto.
  
  * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to
  use TRUE/FALSE macros.  (ftc_gnode_compare): New argument
  `FT_Bool* list_changed' to indicate the change of the cache
  nodes, anyway, it is always FALSE.  (FTC_GNode_Compare):
  New argument `FT_Bool* list_changed' to be passed to
  ftc_gnode_compare().
  * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
  
  * src/cache/ftcsbits.c (ftc_snode_compare): New argument
  `FT_Bool* list_changed' to indicate the change of the cache
  nodes, anyway. It is updated by FTC_CACHE_TRYLOOP().
  (FTC_SNode_Compare): New argument `FT_Bool* list_changed'
  to be passed to ftc_snode_compare().
  * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
