David Turner 9ca782569c * include/freetype/internal/ftmemory.h, src/base/ftbitmap.c, 
src/base/ftmac.c, src/base/ftrfork.c, src/lzw/ftzopen.c,
    src/raster/ftrend1.c, src/sfnt/ttpost.c, src/truetype/ttgxvar.c,
    src/type42/t42parse.c, src/winfonts/winfnt.c: hardening the code
    against out-of-bounds conditions when allocating arrays. This is
    for the cases where FT_NEW_ARRAY and FT_RENEW_ARRAY are not used
    already. Introducing the new FT_ALLOC_MULT and FT_REALLOC_MULT
    macros.

David Turner 264f307e66 * include/freetype/fterrdef.h, include/freetype/config/ftconfig.h, 
include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c,
    src/base/ftutil.c: udpating the memory management functions and
    macros to safely deal with array size buffer overflows, this
    corresponds to attemps to allocate arrays that are too large. For
    an example, consider the following code:

         count = read_uint32_from_file();
         array = malloc( sizeof(Item) * count );
         for ( nn = 0; nn < count; nn++ )
           array[nn] = read_item_from_file();

    if 'count' is larger than FT_UINT_MAX/sizeof(Item), the multiplication
    will overflow and the array allocated will be smaller than the data
    read from the file. In this case, the heap will be trashed, and this
    can be used as a denial-of-service, or make the engine crash later.

    the FT_ARRAY_NEW and FT_ARRAY_RENEW macro now check that the new
    count is no more than FT_INT_MAX/item_size, otherwise, a new error,
    named 'FT_Err_Array_Too_Large' will be returned.

    note that the memory debugger now works again when FT_DEBUG_MEMORY
    is defined, and FT_STRICT_ALIASING has disappeared, the corresponding
    code being now the default.
