Initialize the block range for either RRQ or WRQ. RRQ and WRQ have
different requirements for Start and End. For example, during startup,
WRQ initializes its whole valid block range to [0, 0xffff]. This
is because the server will send an ACK0 to inform the user to start the
upload. When the client receives an ACK0, it will remove 0 from the range,
get the next block number, which is 1, then upload the BLOCK1. For RRQ
without option negotiation, the server will directly send us the BLOCK1
in response to the client's RRQ. When BLOCK1 is received, the client will
remove it from the block range and send an ACK. It also works if there
is option negotiation.
