* Added a Basic DOS protection container/base object for the most common HTTP Server handlers. XMLRPC Handler, GenericHttpHandler and <Various>StreamHandler
* Applied the XmlRpcBasicDOSProtector.cs to the login service as both an example, and good practice.
* Applied the BaseStreamHandlerBasicDOSProtector.cs to the friends service as an example of the DOS Protector on StreamHandlers
* Added CircularBuffer, used for CPU and Memory friendly rate monitoring.
* DosProtector has 2 states, 1. Just Check for blocked users and check general velocity, 2. Track velocity per user,     It only jumps to 2 if it's getting a lot of requests, and state 1 is about as resource friendly as if it wasn't even there.
* Refactor
* Break out common BasicDOSProtector code into separate class.
* Move the BasicDOSProtector.cs to OpenSim.Framework (all useful classes belong there.....)
* Add an IsBlocked(string Key) method so it can be used more generically.   (think..   if we want to rate limit login failures, we could have a call in the Login Service to IsBlocked(uuid.ToString()) and ignore the connection if it returns true, if IsBlocked returns false, we could run the login information and if the login fails we could run the Process method to count the login failures.
* Remove a test *cleanup*
* Add a session concurrency option per key.  Allows developer/config to specify number of concurrent requests on a service.

* Please test
Added support for attachments to group notices when using Flotsam groups.
Merge branch 'master' of ssh://opensimulator.org/var/git/opensim
As discussed on many previous occasions, switch the default physics engine in OpenSimulator from OpenDynamicsEngine to BulletSim.

The BulletSim plugin is higher performance and has a better implementation of vehicles amongst other things.
Many thanks to Robert Adams for making this possible with the enormous amount of work that he has done on this plugin.
If you want to continue using ODE, set physics = OpenDynamicsEngine in the [Startup] section of OpenSim.ini
Fixed rezzing coalesced objects from a prim's inventory

Previously only the first object in the Coalesced Object was rezzed. Now all the objects are rezzed.
BulletSim: implement the SL bug where VEHICLE_HOVER_UP_ONLY disables
the vehicle buoyancy if the vehicle is above its hover height.

This is a known misfeature of this vehicle flag which has been accepted
since it would break too many implementations. The problem is noticed
when creating a jetski-like vehicle that jumps over sand bars. A boat
normally is configured with neutral buoyancy and hovering at water
height. When it jumps the sandbar, it needs to have gravity applied
to get back to water level.
* Fixes mantis mantis 0006803 [PGSQL] - Simulator crashes - Mono.Security.dll missing.    The root of the issue is that the Postgres driver relies on Mono.Security.dll from the mono project.   Unfortunately, when using Mono, including the dll in the distribution causes conflicts.  This solution puts Mono.Security.dll in bin/lib/NET/  and, if windows .NET is the runtime, informs the assembly loader to load bin/lib/NET/Mono.Security.dll when .NET is scanning for the Mono.Security namespace.   On Mono, the included Mono.Security assembly is ignored.
* One More thing, add an appdomain data element to ensure that we don't duplicate the assembly resolving.
