Log Message:
Fixed undefined behaviour in hash()

Shift left on large int values was causing an undefined behaviour, fix it by
operating on unsigned int type instead. This patch changes behaviour of the
hash() slightly - if the computed hash is INT_MIN, the function previously
returned 0, but this case is negligible.
