kai-morich f4166f34a0 read w/o timeout now throws exception on connection lost or buffer to small 
SerialInputOutputManager already returned connection lost exception, as the next read failed

kai-morich f60414f8ec improve write timeout handling 
Return type of write() method changed to void. The return value was redundant before, as it always was the request length or an exception was thrown.

If timeout is reached, write() now throws a SerialTimeoutException with ex.bytesTransferred filled with known transferred bytes.

Added CommonUsbSerialPort.getReadEndpoint() and .getWriteEndpoint() to assist in setting the optimal write buffer size with port.setWriteBufferSize(port.getWriteEndpoint().getMaxPacketSize()).

By default the write buffer size is > MaxPacketSize and the Linux kernel splits writes in chunks. When the timeout occurs, it's unknown how many chunks have already been transferred and the exception typically stores 0. With optimal write buffer size, this value is known and stored in SerialTimeoutException, but due to more kernel round trips write() might take slightly longer().

kai-morich 7423fd9d79 new getControlLines() and getSupportedControLines() methods 
getControlLines() requires less USB calls than calling getRTS() + ... + getRI() individually.
getSupportedControlLines() tells you, which control lines are supported by a driver. Previously you had to check the driver implementation.

kai-morich 9ea936b14a improve close handling 
Use releaseInterface to interrupt read() and terminate SerialInputOutputManager. Previously some drivers used usbRequest.cancel() but this does not interrupt read() on older Android.

Added connection check to read(). Before Android 8.0 request.initialize() did not check usbConnection, which can lead to native crash if NULL
