- Tweaked query parameters (quicker discard, longer requery period).
The analysis suggests that in general the DHT is running okay with some minor issues.
- BitDHT peers respond to ~50% of FIND_NODE queries. This means we drop them,
and so some ONLINE friends, become UNREACHABLE friends.
This appears to be caused by too many FIND_NODE queries reaching BitDHT, and the
peer starts dropping them. This appears to come from specific peers, which
are not RS nodes. Proposed solution is to Track and Filter Over-Querying Peers.
(Only one query per peer every 30 seconds).
- Should be more lenient on the exact query matches.
Allow some dropped messages.
- Queries appear to run longer than necessary.
A better query completion criteria needs to be established.

Now users can sort peers into groups in the friend list, and attribute flags and parent groups to the
directories in the share manager.
Flags are B-B-N, meaning in order:
- browsable for peers in the parent groups
- browsable for everyone
- network wide for everyone
Backward compatibility makes previously BN flags been interpreted as -BN, meaning browsable/network wide for everyone.
Be careful with this new feature. It has been tested, but it's a bit early to rely on it for highly sensitive data.
The merge also includes a significant improvement of the naming of flags with incompatible types
which should sort out some existing bugs as well, since inconsistencies in flag usage have been
found during the process.

- specify how long we store for.
- cleanup old msgs.
- improve printing of history.
- add timeline storage as well.
- disabled by default, enable USE_HISTORY in bdnode.c
There appears to be a bug related to copying bdId's around.
Some of the bootstrap ids are malformed, and this crashes rs.

* Disabled lots of debugging.
* Disabled LOCAL test mode in udpstunner, rsinit
* Enabled BadPeer checking in bitdht.
* Restored normal timeout periods for connection attempts.
* Restored normal connection levels for dht status.

NB: Reverse Most of these changes - before adding to Trunk!!!!
* Added missing BitDht callback functions for test/example code.
* Switch tests/example to OSX compile.
* DISABLE_BAD_PEER_FILTER (as it doesn't like local net)
* Reduced Minimum Peer Counts for DHT to be considered active.
* Added LOCALNET_TESTING to rsinit.cc
- new Commandline Option -R <lport-uport> to restrict UDP ports.
- Enables LocalNet in UdpStunner.

- Updated DhtMode Flags.
- Allowed DhtMode Flags to be set independently.
- Set RelayMode to ConnectionManager.
- Added dropRelayServers() / pingRelayServers()
- Added Support fns for above two functions.

* Enabling Local BadPeer Filter.
- This will remove any peer you detect is spoofing yourself or your friends.
- This list is also shared with you friends. (in Test Mode).
* added Cleanup of BadPeer Filter.
- Instead of permanent ban, peers are be banned for 6 hours.
- bdManager periodically calls this - which prints out ban list too.
* added #define to disable the Filter - for testing purposes.
NOTES: This Ip Filter should probably be moved from DHT level to UdpLayer level.
This will enable it to filter STUN / UDP Connection Packets too.

- At this level it takes significantly longer for the searches to complete, but
there are no DOS warnings on the router. This should hopefully make users happy.
* Added DhtMode() Interface call to dynamically change this rate.
- Can be switched between (HIGH: 50/sec, MED: 20/sec, LOW: 5/sec & TRICKLE: 3/sec)
* Disable additional Queries if PotentialPeer Queue gets too big.

Added Knowledge of Friends, Friends of Friends and Relays.
- Added bdfriendlist class to store information.
- New interface function updateKnownPeer().
- includes IP addresses, if known. (for filtering)
Bad Peer Filtering.
- Check IDs against known peer IP addresses.
- Added checks in checkPotentialPeer().
- Added checks in addPeer().
- Running in TestMode at the moment (Bad Peers are only flagged).
Other Fixes:
- Removed some warning about int/uint comparisons.
- added bdSpace::flagpeer() fn to support above.

* Bandwidth are for RELAY connections.
* Delays are for Exclusive NAT Proxy connections.
* Lots of changes to achieve this. (Mainly added "param" to msgs).
* Various Bugfixes too.
* Updated BITDHT Version to 01 as we've changed Message Format.
* Increased Connection Timeout to 180
* Added extra checks to kill duplicate connections early.

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.

============================================================
This is intended to be a completely independent library from RS,
(hosted at sf.net/projects/bitdht) hence is being commited at the top level.
As initial further development / testing will be driven by RS integration
it is being added to the RS repository. Equally important is ensuring
that RS can compile without requiring aux libraries.
Once libbitdht is further developed, this section of the repository
is expected to be removed... But that will not be for a while, I expect.
