tx_memory_pool: speedup get_complement() for large requests
Changes complexity from M*N to (2*N+M)*log2(M). The FCMP++ stressnet recently hit mempool sizes of ~55k txs.
If the requesting node's mempool is populated, this results in an average of (55000*55000)/2
(about 1.5 billion) comparisons for the responding node. Under this commit, this would be reduced to
(55000+55000)*log2(55000) comparisons (about 2.6 million), a 99.83% reduction.
