Thread support

Asy::op is thread-aware and will link with Threads::Threads when used in CMake. Otherwise, it must be linked with pthread or similar. For now, thread support is limited to a thread -> async operation conversions. Hopefully, it will be extended in future :) Thread support is available in asy/thread.hpp header.

Asyfy

The asy::op library provides a helper (asy::fy()) to quickly convert a blocking call into an asynchronous operation. The implementation isn’t very efficient because a separate thread is created for each asy::fy call. The function supports two types of input arguments.

The first one: functor that calls blocking functions. It is invoked in a separate thread and the return type is used as an output type of the operation handle.

The second one: an instance of the std::future<Output>. The implementation will call .get() in a separate thread and will forward the output into async operation continuation.

There is an overload of asy::fy() that has std::thread as an out parameter. This enables the client code to receive a handle to a newly created thread so the user can wait (join()) for it for proper destruction procedure. The thread will be detached otherwise.
