This involves inserting opensim_reserved_CheckForCoopTermination() calls in lsl -> c# translation at any place where the script could be in a loop with no wait calls.
These places are for, while, do-while, label, user function call and manual event function call.
Call goes through to an XEngineScriptBase which extends ScriptBase.
IEngine is extended to supply necessary engine-specific parent class references and constructor parameters to Compiler.
Unfortunately, since XEngineScriptBase has to be passed WaitHandle in its constructor, older compiled scripts will fail to load with an error on the OpenSim console.
Such scripts will need to be recompiled, either by removing all *.dll files from the bin/ScriptEngines/<region-id> or by setting DeleteScriptsOnStartup = true in [XEngine] for one run.
Automatic recompilation may be implemented in a later commit.
This feature should not yet be used, default remains termination with Thread.Abort() which will work as normal once scripts are recompiled.
It was a dumb idea to try and do a nose over feature for jumping cars anyway.
Add better logging of native shape creation/reuse so can tell the difference.
This makes use of EventWaitHandles since various web references indicate that Thread.Interrupt() can also cause runtime instability.
If co-op termination is enabled, then termination sets the wait handle instead of waiting for a timeout before possibly aborting the thread.
This allows the script to cleanly terminate if it's in a llSleep/LL function delay or the next time it enters such a wait without any timeout period.
Co-op termination is not yet testable since checking for termination request within loops that never trigger a wait is not yet implemented.
This commit, unlike 1b5c41c, passes the wait handle as an extra parameter through IScript.Initialize() instead of passing IScriptInstance itself.

This is to allow the future co-operative script thread terminate feature to detect and act upon termination requests.
This splits the assembly and state loading out from the ScriptInstance() constructor to a separate Load() method
in order to facilititate continued script logic regression testing.

This os function is a little different than the others in that it
does not throw an exception of one is not privilaged to use it.
It merely returns an empty string.
This workaround relies on the fact that a closing client goes inactive before the attachments derez calls happen.
This reverts the change to remove scripts too early instead of stopping them, since the the two step stop then remove is necessary to execute the detach event.
This involves making Attachments module listen for start/stop script changes.
It also involves removing the script from the region on detach in the same manner as every other DeleteSceneObject() call rather than simply stopping it
This is necessary tue to the bad assymetry of start and stop script triggers but it appears to be the correct behaviour anyway, as detached objects are completely gone from the sim.
Not just in a state where their scripts have been stopped.
