[Fontconfig] [PATCH] fix crashes on malformed fonts.cache

[Dirk Mueller]

Hi, 

This one fixes a memory overrun when a fonts.cache file is slightly malformed. 
other places probably need similiar fixes. 

Thanks,
Dirk

	* fcfs.c (FcFontSetUnserialize): Make sure there is no
	integer overflow when reading the cache file.
