Fix CVE-2018-11202 (#3330)
A malformed file could result in chunk index memory leaks. Under most
conditions (i.e., when the --enable-using-memchecker option is NOT
used), this would result in a small memory leak and and infinite loop
and abort when shutting down the library. The infinite loop would be
due to the "free list" package not being able to clear its resources
so the library couldn't shut down. When the "using a memory checker"
option is used, the free lists are disabled so there is just a memory
leak with no abort on library shutdown.
The chunk index resources are now correctly cleaned up when reading
misparsed files and valgrind confirms no memory leaks.
