usb-serial-for-android: Implement timeout-handling
Since the Android USB stack and subsequently the usb-serial-for-android driver have problems with read-timeouts, the read-timeout is now implemented in AndroidSerial.java. Also, DC_STATUS_TIMEOUT is returned if there are less bytes returned than expected. Different chipsets seem to behave differently with usb-serial-for-android. On CP210x the read blocks until there is some data here, but on FTDI the chip seems to return whatever is currently in the buffer (so 0 bytes if the buffer is empty). This different behaviour should be mitigated by the changes by this commit. Signed-off-by: Christof Arnosti <charno@charno.ch>
