Generates human-readable hexdump of the data sent or received by connection.
`path` is a file name where hexdump should be written. `num_bytes` is
a number of bytes sent/received. `ev` is one of the `MG_*` events sent to
an event handler. This function is supposed to be called from the
event handler.
