[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.

[cache] Fit FTC_GNode_Compare() to FTC_Node_CompareFunc.
* src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
argument `FTC_Cache cache' to fit FTC_Node_CompareFunc
prototype.
* src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
`cache' is not used by its child ftc_gnode_compare().

[cache] inline-specific functions are conditionalized.
* src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized
for inlined config. This function is a thin wrapper of
ftc_gnode_compare() for inlined FTC_CACHE_LOOKUP_CMP()
(see `nodecmp' argument). Under non-inlined config,
ftc_gnode_compare() is invoked by FTC_Cache_Lookup(),
via FTC_Cache->clazz.node_compare().
* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
* src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto,
for ftc_snode_compare().
* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.

[cache] Correct a type mismatch under non-inlined config.
* src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP):
FTC_GCache_Lookup() takes the node via a pointer `FTC_Node*',
differently from cpp-macro FTC_CACHE_LOOKUP_CMP().

[cache] Change the hash types to FT_PtrDist.
On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
variables are inappropriate to calculate hash values
from the memory address (64-bit). The hash variables
are extended from FT_ULong to FT_PtrDist and new
hashing macro functions are introduced. The hash
values on 16-bit memory platforms are changed, but
ILP32 and LP64 are not changed. The hash value in
the cache subsystem is not reverted to the memory
address, so using signed type FT_PtrDist is safe.
* src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash
function to replace FTC_FACE_ID_HASH() for portability.
* src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace
FTC_FACE_ID_HASH() by _FTC_FACE_ID_HASH().
* src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.
* src/cache/ftccache.h (FTC_NodeRec): The type of the
member `hash' is changed from FT_UInt32 to FT_PtrDist.
* src/cache/ftccache.h (FTC_Cache_Lookup): The type of the
argument `hash' is changed from FT_UInt32 to FT_PtrDist.
(FTC_Cache_NewNode): Ditto.
* src/cache/ftccache.c (ftc_cache_add): Ditto.
(FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto.
* src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto.
* src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto.
* src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type
of the internal variable `hash' is changed to FT_PtrDist
from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto.
(FTC_SBitCache_Lookup): Ditto.
(FTC_SBitCache_LookupScaler): Ditto.
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.
* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto.
Also the type of the internal variable `_idx' is changed to
FT_PtrDist from FT_UInt32 for better pointer calculation.

src/cache/ftcsbits.h, src/cache/ftcmanag.h, src/cache/ftccmap.h,
src/cache/ftcmru.h: copying the cache's internal header files which
were located in 'include/freetype/cache' to the 'src/cache' directory
instead.
Note that these files are not used by FreeType clients, all cache
public APIs have been already moved to include/freetype/ftcache.h,
and the FT_CACHE_INTERNAL_XXXX_H macros all resolve to it.
the move is to allow us to modify the internals without intereference
from rogue clients. Note that there are no known client that accesses
the cache internals at the moment.
