| * | drop vAddrToSend after sending big addr messageKaz Wesley2016-06-061-0/+3
| | | | | | | | | | | | | | | | | | We send a newly-accepted peer a 1000-entry addr message, and then only use vAddrToSend for small messages. Deallocate vAddrToSend after it's been used for the big message to save about 40 kB per connected inbound peer.

Since the mempool is DynamicUsage-regulated, this will translate to a larger mempool in the same amount of space. Map value type: eliminate the vin index; no users of the map need to know which input of the transaction is spending the prevout. Map key type: replace the COutPoint with a pointer to a COutPoint. A COutPoint is 36 bytes, but each COutPoint is accessible from the same map entry's value. A trivial DereferencingComparator functor allows indirect map keys, but the resulting syntax is misleading: `map.find(&outpoint)`. Implement an indirectmap that acts as a wrapper to a map that uses a DereferencingComparator, supporting a syntax that accurately reflect the container's semantics: inserts and iterators use pointers since they store pointers and need them to remain constant and dereferenceable, but lookup functions take const references.

The use of the mempool for this was added as part of the mempool p2p message and is only needed to fetch transactions returned by it.
