BMidiPort

Marcus you are write this memory leak need to be corected.

I tried to compile a program with Class BMidi, BMidiText, BMidiStore 
from libMidi.so (Be) and I put libMidi2.so into the trash that compile 
and that run normally, then I think LibMidi2 is not used with that 
class.Right=3F
But when I we use a BMidiPort that compile but not run.

For the class BMidiPort I think that just a class that translate BMidi 
data to BMidiEndpoint data. The hardware midi port are created by the 
midi=5Fserver as BMidiProducer or BMidiConsumer, and BMidiPort just send 
or receive data.

A+
