Merged from /branches/v0.5-peernet/libbitdht:r4357-4397

Browse Source 
Bugfixes and a couple of small improvements to the DHT code.
 * fixed up buggy overloading for the udplayer (for testing).
 * added processing multiple (5) remote processes per tick. 
     - (1 wasn't enough in testing, and led to dropped peers) 
 * removed unused variables from query data structure.
 * #defined out debugging in bdSpace, removed old functions.
 * More agressive attempts to find proxies for connections.
 * made "final query attempt" use exact peer address rather than midid.
     - mid id meant that the target wasn't always returned.
 * tweaked bdconnection debugging.
 * increase CONNECTION_MAX_TIMEOUT from 30 => 45. wasn't enough!
 * Limited bdQuery::QueryIdlePeriod to 15min (was unlimited).
 * added bdQuery::PotentialPeer cleanup functions - for more robust reporting.
 * fixed bdQuery debugging printouts.
 * Implemented BITDHT_QFLAGS_UPDATES flag.
