Unix: add SerialPort.read(byte[] buffer)

[ghost]

A function that receives a buffer and fill it can be very useful.

Alternatively, the input stream interface (#17) would be able to do this.

IMHO, It would be much more useful to have the following method implemented natively:

public int read(byte buffer[], int offs, int len);

this will give two advantages:

1. the read(byte buffer[]) can be simply implemented through java as:

public int read(byte buffer[]) {
  return read(buffer, 0, buffer.length);
}

2. both methods can be used to implement the InputStream interface.
