Port zenoh_c to zenoh_cpp

[ahcorde]

For visibility reason I created a branch called dev/1.0.0 in this repository, otherwise I can't open the PR

The goal of this PR is to port the zenoh_c API to zenoh_cpp.

I added a hack in the zenoh_cpp API to be able to make the transition easier. Edit the following file:

nano +83 install/opt/zenoh_cpp_vendor/include/zenoh/api/base.hxx

And add this change:

public:
    OwnedType _0;
protected:

---

• zenohd is ported to zenoh_cpp
