this avoids the usage of the unique_ptr PROTO::protocol before it has
been constructed incase one wants to log something inside the
constructor itself, move the logging to macros and print file:linenumber
on ERR,CRIT,WARN and classname on the rest of the levels.
* protocols: avoid undefined behaviour in C macro
to safely use wl_container_of with a class the class has to be no
virtual functions, no inheritance, and uniform access control (e.g all
public)
work around this by putting this into a destroywrapper struct.
* opengl: clean memory on destruction
add a destructor and free the allocated memory and close the fd
