Onder Kalaci a333c9f16c Add infrastructure for distributed deadlock detection 
This commit adds all the necessary pieces to do the distributed
deadlock detection.

Each distributed transaction is already assigned with distributed
transaction ids introduced with
3369f3486f. The dependency among the
distributed transactions are gathered with
80ea233ec1.

With this commit, we implement a DFS (depth first seach) on the
dependency graph and search for cycles. Finding a cycle reveals
a distributed deadlock.

Once we find the deadlock, we examine the path that the cycle exists
and cancel the youngest distributed transaction.

Note that, we're not yet enabling the deadlock detection by default
with this commit.
