Enable use of a different proxy for .onion addresses. This implements --onion (and --onionuser/--onionpass) that enable a different proxy to be used to connect to .onion addresses. If no main proxy is supplied then no proxy will be used for non-onion addresses. Additionally we add --noonion that blocks connection attempts to .onion addresses entirely (and avoids using tor for proxy dns lookups). the --tor option has been supersceded and thus removed. Closes #47

Implement banning based on dynamic ban scores Dynamic ban scores consist of a persistent and a decaying component. The persistent score can be used to create simple additive banning policies simlar to those found in other bitcoin node implementations. The decaying score enables the creation of evasive logic which handles misbehaving peers (especially application layer DoS attacks) gracefully by disconnecting and banning peers attempting various kinds of flooding. Dynamic ban scores allow these two approaches to be used in tandem. This pull request includes the following: - Dynamic ban score type & functions, with tests for core functionality - Ban score of connected peers can be queried via rpc (getpeerinfo) - Example policy with decaying score increments on mempool and getdata - Logging of misbehavior once half of the ban threshold is reached - Banning logic can be disabled via configuration (enabled by default) - User defined ban threshold can be set via configuration

wire: Implement SFNodeBloom (BIP0111). SFNodeBloom is a new service flag that a node is required to use to indicate that it supports bloom filtering. This includes a protocol version bump to 70011 and a wire version bump to 0.3.0. btcd: The SFNodeBloom flag is set by default. A new configuration option --nopeerbloomfilters has been added to to disable bloom filtering. Any node advertising a version greater than or equal to 70011 that attempts to use bloom filtering will be disconnected if bloom filtering is disabled. This mimics Bitcoin Core commit afb0ccaf9c9e4e8fac7db3564c4e19c9218c6b03

The result is passed to the jsonRPCRead function and to the WebsocketHandler function in rpcwebsocket.go.

Add support for an optional address-based transaction index. * Address index is built up concurrently with the `--addrindex` flag. * Entire index can be deleted with `--dropaddrindex`. * New RPC call: `searchrawtransaction` * Returns all transacitons related to a particular address * Includes mempool transactions * Requires `--addrindex` to be activated and fully caught up. * New `blockLogger` struct has been added to factor our common logging code * Wiki and docs updated with new features.

Integrate a valid ECDSA signature cache into btcd Introduce an ECDSA signature verification into btcd in order to mitigate a certain DoS attack and as a performance optimization. The benefits of SigCache are two fold. Firstly, usage of SigCache mitigates a DoS attack wherein an attacker causes a victim's client to hang due to worst-case behavior triggered while processing attacker crafted invalid transactions. A detailed description of the mitigated DoS attack can be found here: https://bitslog.wordpress.com/2013/01/23/fixed-bitcoin-vulnerability-explanation-why-the-signature-cache-is-a-dos-protection/ Secondly, usage of the SigCache introduces a signature verification optimization which speeds up the validation of transactions within a block, if they've already been seen and verified within the mempool. The server itself manages the sigCache instance. The blockManager and txMempool respectively now receive pointers to the created sigCache instance. All read (sig triplet existence) operations on the sigCache will not block unless a separate goroutine is adding an entry (writing) to the sigCache. GetBlockTemplate generation now also utilizes the sigCache in order to avoid unnecessarily double checking signatures when generating a template after previously accepting a txn to the mempool. Consequently, the CPU miner now also employs the same optimization. The maximum number of entries for the sigCache has been introduced as a config parameter in order to allow users to configure the amount of memory consumed by this new additional caching.

Implement a built-in concurrent CPU miner. This commit implements a built-in concurrent CPU miner that can be enabled with the combination of the --generate and --miningaddr options. The --blockminsize, --blockmaxsize, and --blockprioritysize configuration options wich already existed prior to this commit control the block template generation and hence affect blocks mined via the new CPU miner. The following is a quick overview of the changes and design: - Starting btcd with --generate and no addresses specified via --miningaddr will give an error and exit immediately - Makes use of multiple worker goroutines which independently create block templates, solve them, and submit the solved blocks - The default number of worker threads are based on the number of processor cores in the system and can be dynamically changed at run-time - There is a separate speed monitor goroutine used to collate periodic updates from the workers to calculate overall hashing speed - The current mining state, number of workers, and hashes per second can be queried - Updated sample-btcd.conf file has been updated to include the coin generation (mining) settings - Updated doc.go for the new command line options In addition the old --getworkkey option is now deprecated in favor of the new --miningaddr option. This was changed for a few reasons: - There is no reason to have a separate list of keys for getwork and CPU mining - getwork is deprecated and will be going away in the future so that means the --getworkkey flag will also be going away - Having the work 'key' in the option can be confused with wanting a private key while --miningaddr make it a little more clear it is an address that is required Closes #137.

Update sample config file. This commit adds a couple of options which were not details in the sample config file. It also fixes a couple of typos and makes the example default maxpeers setting in the config file match the actual default used in btcd.
