This should also make it less likely that an event will be erroneously posted during a state change by precluding a race condition with a thread calling ScriptInstance.PostEvent()
This is to address an issue where HTTP script functions could make calls to localhost and other endpoints inside the simulator's LAN.
By default, calls to all private addresses are now blocked as per http://en.wikipedia.org/wiki/Reserved_IP_addresses
If you require exceptions to this, configure [Network] OutboundDisallowForUserScriptsExcept in OpenSim.ini
Add permission by identifying uuid (owner/creator/group) and function. Revoke
permission in the same manner. Permission adjustments immediately effect
running scripts ability to call os functions.

This takes the AsyncCommandHandler.staticLock.
However, AsyncCommandHandler.DoOneCmdHandlerPass() already holds staticLock and may attempt to take the EventQueue lock via ScriptInstance.PostEvent() in XEngine.CheckListeners()
This is a regression from faaf47a (Fri Jan 16 2015) but not simply reverting that commit since it will reintroduce a race between script removal, backup and event queue manipulating code.
This does not work on Windows since the VM retains a handle to the DLL even if class instantiation was unsuccessful.
Which causes deletion of the old DLL to fail with access sharing violations.
Instead, log a warning in this situation asking the user to manually set DeleteScriptsOnStartup = true for a session (or one could separately delete the DLLs in the relevant bin/scriptengines/<region-uuid> dir
For the current session, the script engine will continue using the script compiled stop strategy as before.

This is to see if this helps with the problem in http://opensimulator.org/mantis/view.php?id=7278 where some DLLs are not allowing this.
Since OpenSim created the file it should always be allowed to delete it.
This eliminates pointless work and exceptions when an appdomain is unloaded whilst an attachment script state is persisted.
Adds test for this case.

- It establishes 4 digits for opensim versions
- It uses the same number between opensim releases and mono addins versions
It also eliminates the last addin.xml files that were still there, for consistency.
This was beause the code was finding the script DLL compiled for the source region as everything is in the same appdomain and using this as the location for the destination script state, etc.
This resolves the regression by passing the proper destination separately from the DLL retrieved.
Probably a regression since commit d7b92604 (11 July 2014).
Added regression test for this case.
At least partly addresses http://opensimulator.org/mantis/view.php?id=7278
If log level is 1 then every script load is logged.
This means the <logger name="OpenSim.Region.ScriptEngine.XEngine"> section in OpenSim.exe.config is no longer needed to avoid log spam on regions with many scripts and can be removed.
