Previously the script state was never saved for a !Running script, so upon region restart the script would be Running again.
The use of the 'StayStopped' flag is needed because all scripts are automatically stopped when the region shuts down, but in that case we shouldn't save in their state that they're !Running.
Notes:
- This metric provides a better indication of which scripts are taking up a lot of CPU (and therefore should be optimized).
- Previously the execution time was reset to 0 in every new measurement period, causing the reported time to fluctuate for no reason. This has been fixed by using a sliding window.
1. Use a Stopwatch (a high-resolution timer)
2. Whenever we start a new measurement period, zero out the total execution time (previously it just kept accumulating)
3. Changed the measurement period from 30 minutes to 30 seconds. This is much more useful in the "Top Scripts" dialog, as it shows currently active scripts
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 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.
Setting m_CurrentCompile = null in the finally block reduces the risk that an exception could permanently stop any future scripts compiling until the simulator is restarted.
If an exception is seen from this then please report and further changes to fix the bug or improve compiling reliability can be made.
co-op should be more stable as it doesn't abort threads, which can trigger virtual machine instability
This change will be invisible to users as script DLLs are recompiled automatically where necessary, though the change won't take affect until the next simulator restart.
This change has no effect on existing script state.
If you want to continue using abort, set ScriptStopStrategy = abort in the [XEngine] section of OpenSim.ini
We have to do this since we can't unload existing DLLs if they're all in the same AppDomain.
But we can still update the underlying DLL which will be used in the next simulator session.
SmartThreadPool code comes from http://www.codeproject.com/Articles/7933/Smart-Thread-Pool
This version implements thread abort (via WorkItem.Cancel(true)), threadpool naming, max thread stack, etc. so we no longer need to manually patch those.
However, two changes have been made to stock 2.2.3.
Major change: WorkItem.Cancel(bool abortExecution) in our version does not succeed if the work item was in progress and thread abort was not specified.
This is to match previous behaviour where we handle co-operative termination via another mechanism rather than checking WorkItem.IsCanceled.
Minor change: Did not add STP's StopWatch implementation as this is only used WinCE and Silverlight and causes a build clash with System.Diagnostics.StopWatch
The reason for updating is to see if this improves http://opensimulator.org/mantis/view.php?id=6557 and http://opensimulator.org/mantis/view.php?id=6586
