Details:


With some USB <-> RS-232 adapters avrdude sometimes has problems to get in
sync with the stk500. It seems that the first few characters  from the serial
port get lost just after opening the port.

To make the sync more reliable, this patch sends the GET_SYNC command and
drains the serial port right away a few times, before trying the real
synchronization mechanism.

Works OK for me, and I don't think any side effects will occur.
