This makes it possible to use the dedupliicating service without needing to migrate all the existing asset data beforehand.
Currently controlled by a ChainedServiceModule setting in [AssetService] (e.g. ChainedServiceModule = "OpenSim.Services.AssetService.dll:AssetService")
Not yet ready for use.
This is mostly Bluewall's work but I am also bumping the general version number
OpenSimulator 0.7.5 remains in the release candidate stage.
I'm doing this because master is significantly adding things that will not be in 0.7.5
This update should not cause issues with existing external binary DLLs because our DLLs do not have strong names
and so the exact version match requirement is not in force.
This allows us to use a common check for both AssetService and XAssetService.
It also allows future console commands to delete an asset.
As before, deletion of maptile assets is not allowed remotely unless this is explicitly configured.
Make AssetServiceConnector return more useful data on failure, such as what DLL it was trying to load
Allow LocalAssetServiceConnector.GetData() to work without a cache present, as works for the other lasc Get* methods.
The asset data plugin now implements IXAssetData rather than IAssetData so the ordinary AssetService should no longer pick it up.
This replaces the changes in 92b1ade. There is no longer any need to adjust your StandaloneCommon.ini/Robust.ini/Robust.HG.ini files.
This may explain very recent issues in the last few weeks where textures have been disappearing or turning white (as they were going to different places).
Unfortunately, you will need to rollback to an earlier database backup or reupload the textures.
This is the start of exploring the creation of a bundled OpenSimulator asset service that does de-duplication and possibly file storage of assets.
Along the lines of coyled's SRAS, but not intended to replace, merely to act as a more performant bundled default.
Might end up nicking stuff from kcozen's patch at http://opensimulator.org/mantis/view.php?id=5429

Feedback and discussion welcome as commits are made.
Now, such excpetions are caught by an exception handler and just an error message is shown.
This was the kind of exception causing these fatal server crashes:
APPLICATION EXCEPTION DETECTED: System.UnhandledExceptionEventArgs^M
^M
Exception: System.ArgumentOutOfRangeException: Argument is out of range.
Parameter name: offset exceeds the size of buffer
at System.Net.Sockets.NetworkStream.BeginRead (System.Byte[] buffer, Int32 offset, Int32 size, System.AsyncCallback callback, System.Object state) [0x00000] in <filename unknown>:0
at HttpServer.HttpClientContext.OnReceive (IAsyncResult ar) [0x00000] in <filename unknown>:0 ^M
^M
Application is terminating: True^M
We compare existing and loaded asset by doing an SHA1 on both, so that a changed library asset will still update the store.
This cuts asset library load time from 10 seconds to <1 sec.
Note, a fix on the previous commit revealed a bug where a library script cannot be copied except on the first login after a cache clear.
This is unrelated to this commit and needs to be fixed at some subsequent time.
From pure code inspection, it looks like the uuid gatherer may get most asset uuids because the scene object serializer naively pulls non-root parts from all contained scene objects into one mega-object. However, root part uuids may well still be missing, and there may be other odd artifacts from this bug.
It appears that storing the size of the coalescence and the offsets is redundant, since one can work out this information from the position data already in the scene object groups.
