Macro for the creation of a pipe.
Automates the creation of a ring buffer and the pipe.
arg_name is the variable name and string name of the pipe.
arg_state is the given state, which can be used in the function.
arg_size is the ring buffer size in bytes.
arg_conn_count is the number of outgoing connections.
arg_state is the given state, which can be used in the function.
arg_log is the log function, called when an element is sent.
