BUG#20257: Fix partition pruning for BIGINT UNSIGNED, interval walking:
- provide special handling for an edge case of interval of size 4G-1.
- Store interval size in ulonglong, not uint (it was possible to miss partitions this way)
- In get_next_partition_via_walking(), interpret the value of walked-over field as having the
same "signedness" as field (this is so because this value was obtained by calling field->val_int())
- Remove out of date todo comment.
