Instead of reinterpret_casting to an possibly unrelated promise_base, this patch uses the common base_lco base for the managed_promise shim.
the promise is allocated as promise<void>, however the continuation tried to trigger a promise<unused_type>, this triggers UB and has been fixed in this patch. Flyby: Some cleanup of basic_action.hpp and continuation.hpp
This patch fixes a problem when the result type specified for packaged_action does not match the action's local result type. This led to the continuation calling the set_value_nonvirt function on an object of wrong type.

Might have been a good idea to replace boost::mpl::true_/false_ here as well - all the rest of the file has been switched to <type_traits>.

The Problem here is that is_future returns a boost::mpl type. I wanted to
avoid changing too much unrelated stuff in one PR.
…uture Removed special handling of typed_continuation<([shared_]future<R>> and replaced it with free function handling of future return types.

This function is throwing an exception if creation goes wrong. I don't think we should silently return invalid_gid in case of an error in the constructor.
