This commit changes the count n_sent_push_requests to time_t based push_request_timeout. This is more in line to our other timeouts which are also time based instead of number retries based.
This does not change the behaviour but it prepares allowing to extend the pull request timeout during a pending authentication. As a user visible change we print the the time we waited for a timeout instead Also update the man page to actually document that hand-window controls this timeout.
