Incrementally update mempool index 
This should significantly improve resource usage when the
mempool has thousands of pending transactions.

Do not require txindex over the full node 
Lookup confirmed transactions only at their blocks (using
the `blockhash` parameter of `getrawtransaction` RPC).

Note that seeking inside a block (on a HDD) doesn't take
too much time when compare to reading the whole block and
finding the transaction (even without a client-side cache).

Note: txindex takes ~16GB today (over Bitcoin mainnet).

Allow specifying blockheader during transaction lookup via daemon 
This would allow to work without daemon's txindex.

Note that seeking inside a block (on a HDD) doesn't take
too much time when compare to reading the whole block and
finding the transaction (even without client-side cache).

Next commit should add support for looking up confirmation
height for a given transaction ID (currently assumes txindex).

Allow querying mempool directly for transactions 
This would allow querying the daemon only for confirmed transactions.
