2016-10-17Kill insecure_random and associated global stateWladimir J. van der Laan
There are only a few uses of `insecure_random` outside the tests. This PR replaces uses of insecure_random (and its accompanying global state) in the core code with an FastRandomContext that is automatically seeded on creation. This is meant to be used for inner loops. The FastRandomContext can be in the outer scope, or the class itself, then rand32() is used inside the loop. Useful e.g. for pushing addresses in CNode or the fee rounding, or randomization for coin selection. As a context is created per purpose, thus it gets rid of cross-thread unprotected shared usage of a single set of globals, this should also get rid of the potential race conditions. - I'd say TxMempool::check is not called enough to warrant using a special fast random context, this is switched to GetRand() (open for discussion...) - The use of `insecure_rand` in ConnectThroughProxy has been replaced by an atomic integer counter. The only goal here is to have a different credentials pair for each connection to go on a different Tor circuit, it does not need to be random nor unpredictable. - To avoid having a FastRandomContext on every CNode, the context is passed into PushAddress as appropriate. There remains an insecure_random for test usage in `test_random.h`.

2016-09-08net: Pass best block known height into CConnmanCory Fields
CConnman then passes the current best height into CNode at creation time. This way CConnman/CNode have no dependency on main for height, and the signals only move in one direction. This also helps to prevent identity leakage a tiny bit. Before this change, an attacker could theoretically make 2 connections on different interfaces. They would connect fully on one, and only establish the initial connection on the other. Once they receive a new block, they would relay it to your first connection, and immediately commence the version handshake on the second. Since the new block height is reflected immediately, they could attempt to learn whether the two connections were correlated. This is, of course, incredibly unlikely to work due to the small timings involved and receipt from other senders. But it doesn't hurt to lock-in nBestHeight at the time of connection, rather than letting the remote choose the time.
2016-09-08net: move nLocalServices/nRelevantServices to CConnmanCory Fields
These are in-turn passed to CNode at connection time. This allows us to offer different services to different peers (or test the effects of doing so).

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.
