Shared object loading experiment in C++

Each plugin must #include <wharf/cargo.hpp> and provide a statically initialized instance of a wharf::cargo, like so:

#include "wharf/cargo.hpp"

auto plugin = wharf::cargo{ "my_plugin", [](){
    // Do stuff when sucesfully loaded here
}};

or like so:

#include "wharf/cargo.hpp"

struct my_plugin : public wharf::cargo
{
    my_plugin() : wharf::cargo{ "my_plugin" }
    {
        if(is_boated)
        {
            // Do stuff when sucesfully loaded here
        }
    }
};

auto plugin = my_plugin{};

The host application just needs to #include <wharf/host.hpp> or provide its own wharf::vessel() implementation. Refer to wharf/host.hpp, it's quite simple.

NOTE: The host application needs to be compiled with -rdynamic.
