smbget: Adds a rate limiting option --limit-rate in KB/s
This patch implements a very simple rate limiter. It works by pausing the main
download loop whenever the bytes transferred are more than what we would get
with if it were transferred at the rate set by the user.
Please note that this may reduce the blocksize if the limit is too small.
