0814da4e9d Only use AddInventoryKnown for transactions 
filterInventoryKnown is only used when relaying transactions,
so stop adding block hashes to the filter.

eeded98dce Handle mempool requests in send loop, subject to trickle 
By eliminating queued entries from the mempool response and responding only at
trickle time, this makes the mempool no longer leak transaction arrival order
information (as the mempool itself is also sorted)-- at least no more than
relay itself leaks it.

05c3d2e290 Eliminate TX trickle bypass, sort TX invs for privacy and priority. 
Previously Bitcoin would send 1/4 of transactions out to all peers
 instantly.  This causes high overhead because it makes >80% of
 INVs size 1.  Doing so harms privacy, because it limits the
 amount of source obscurity a transaction can receive.

These randomized broadcasts also disobeyed transaction dependencies
 and required use of the orphan pool.  Because the orphan pool is
 so small this leads to poor propagation for dependent transactions.

When the bypass wasn't in effect, transactions were sent in the
 order they were received.  This avoided creating orphans but
 undermines privacy fairly significantly.

This commit:
 Eliminates the bypass. The bypass is replaced by halving the
  average delay for outbound peers.

 Sorts candidate transactions for INV by their topological
  depth then by their feerate (then hash); removing the
  information leakage and providing priority service to
  higher fee transactions.

 Limits the amount of transactions sent in a single INV to
  7tx/sec (and twice that for outbound); this limits the
  harm of low fee transaction floods, gives faster relay
  service to higher fee transactions. The 7 sounds lower
  than it really is because received advertisements need
  not be sent, and because the aggregate rate is multipled
  by the number of peers.

10ea8235a8 Fix exit codes: 
- `--help`, `--version` etc should exit with `0` i.e. no error ("not enough args" case should still trigger an error)
- error reading config file should exit with `1`

Slightly refactor AppInitRPC/AppInitRawTx to return standard exit codes (EXIT_FAILURE/EXIT_SUCCESS) or CONTINUE_EXECUTION (-1)
