Siddhesh Poyarekar 303e567a80 Check for integer overflow in cache size computation in strcoll ...

strcoll is implemented using a cache for indices and weights of
collation sequences in the strings so that subsequent passes do not
have to search through collation data again.  For very large string
inputs, the cache size computation could overflow.  In such a case,
use the fallback function that does not cache indices and weights of
collation sequences.

Fixes CVE-2012-4412.
