cobalt::channel does not work with move only type

[dchansen]

The channel class requires that the value type be copyable, so things like unique_ptrs cannot be used with it.

This example (for instance) does not compile:

#include <boost/cobalt.hpp>
#include <any>
#include <memory>

namespace bc = boost::cobalt;

struct OnlyOne {
    OnlyOne() = default;
    OnlyOne(const OnlyOne&) = delete;
    OnlyOne( OnlyOne&&) = default;
};

bc::task<void> test(){
    bc::channel<OnlyOne> c;
    co_await c.write(OnlyOne());       
}

Thanks for reporting. I created fixes for both your issues, can you check if they fix all problems?

Thanks for the quick response. Your patch fixed both issues.
