* debugger-agent.c: Verify TLS lookup in thread_end callback.

proper fix for Hashtable serialization under the web profile (unity_web defines both NET_2_1 and MONOTOUCH so better to just rely on UNITY instead)

 * debugger-agent.c: Allow runtime to survive not being able to listen for attachments.

 * debugger-agent.c: Unregress non-windows runtime shutdown.

	* verify.c: mono_class_is_assignable_from can't handle
	IList<GTD<T>> x GTD[] since GTD[] won't have the right
	iface slots set. This isn't a problem for the runtime
	since GTD[] will never happen as it's an unrealizable type.

	Fixes #663815

 * debugger-agent.c: Fix race-to-crash on runtime shutdown.

License: MIT/X11

Add feature that warns us whenever we build the unity_web profile, and we do not ship a type that we did ship before. Prevents us form accidentally breaking bw compatibility.

	* profiler.c: allow multiple profiler engines to be loaded
	at the same time.
