/** Stochastic address manager
*
* Design goals:
* * Keep the address tables in-memory, and asynchronously dump the entire to able in peers.dat.
* * Make sure no (localized) attacker can fill the entire table with his nodes/addresses.
*
* To that end:
* * Addresses are organized into buckets.
* * Address that have not yet been tried go into 1024 "new" buckets.
* * Based on the address range (/16 for IPv4) of source of the information, 64 buckets are selected at random
* * The actual bucket is chosen from one of these, based on the range the address itself is located.
* * One single address can occur in up to 8 different buckets, to increase selection chances for addresses that
* are seen frequently. The chance for increasing this multiplicity decreases exponentially.
* * When adding a new address to a full bucket, a randomly chosen entry (with a bias favoring less recently seen
* ones) is removed from it first.
* * Addresses of nodes that are known to be accessible go into 256 "tried" buckets.
* * Each address range selects at random 8 of these buckets.
* * The actual bucket is chosen from one of these, based on the full address.
* * When adding a new good address to a full bucket, a randomly chosen entry (with a bias favoring less recently
* tried ones) is evicted from it, back to the "new" buckets.
* * Bucket selection is based on cryptographic hashing, using a randomly-generated 256-bit key, which should not
* be observable by adversaries.
* * Several indexes are kept for high performance. Defining DEBUG_ADDRMAN will introduce frequent (and expensive)
* consistency checks for the entire data structure.

* - unspentness bitvector, for vout[2] and further; least significant byte first
* - the non-spent CTxOuts (via CTxOutCompressor)
* - VARINT(nHeight)

* The nCode value consists of:
* - bit 1: IsCoinBase()
* - bit 2: vout[0] is not spent
* - bit 4: vout[1] is not spent
* - The higher bits encode N, the number of non-zero bytes in the following bitvector.
* - In case both bit 2 and bit 4 are unset, they encode N-1, as there must be at
* least one non-spent output).
