2016-09-08net: move messageHandlerCondition to CConnmanCory Fields
2016-09-08net: move nLocalHostNonce to CConnmanCory Fields
This behavior seems to have been quite racy and broken. Move nLocalHostNonce into CNode, and check received nonces against all non-fully-connected nodes. If there's a match, assume we've connected to ourself.

2016-08-23Added feeler connections increasing good addrs in the tried table.Ethan Heilman
Tests if addresses are online or offline by briefly connecting to them. These short lived connections are referred to as feeler connections. Feeler connections are designed to increase the number of fresh online addresses in tried by selecting and connecting to addresses in new. One feeler connection is attempted on average once every two minutes. This change was suggested as Countermeasure 4 in Eclipse Attacks on Bitcoin’s Peer-to-Peer Network, Ethan Heilman, Alison Kendler, Aviv Zohar, Sharon Goldberg. ePrint Archive Report 2015/263. March 2015.

Also fix up a few small issues: - Lookup with "badip:port" now sets the port to 0 - Don't allow assert to have side-effects

2016-07-31net: narrow include scope after moving to netaddressCory Fields
Net functionality is no longer needed for CAddress/CAddrman/etc. now that CNetAddr/CService/CSubNet are dumb storage classes.

2016-06-15Allow disconnecting a netgroup with only one member in eviction.Gregory Maxwell
With the latest additions there are enough protective measures that we can take the training wheels off.
2016-06-15Add recently accepted blocks and txn to AttemptToEvictConnection.Gregory Maxwell
This protects any not-already-protected peers who were the most recent four to relay transactions and most recent four to send blocks to us.

2016-06-13Rework addnode behaviourPieter Wuille
* Use CNode::addeName to track whether a connection to a name is already open * A new connection to a previously-connected by-name addednode is only opened when the previous one closes (even if the name starts resolving to something else) * At most one connection is opened per addednode (even if the name resolves to multiple) * Unify the code between ThreadOpenAddedNodeConnections and getaddednodeinfo * Information about open connections is always returned, and the dns argument becomes a dummy * An IP address and inbound/outbound is only reported for the (at most 1) open connection
