Details:

If there is only one timeout then when the handler is called there will be
none. If the handler then calls sys_timeout to install another handler and
then sys_timeout will reset the timeouts_last_time. When the handler returns
to the sys_check_timeouts loop it was continuing to use a stale diff value and
incorrectly checking the times.

This patch modifies sys_check_timeouts to sample sys_now() and
timeouts_last_time each time around the loop. This allowed some cleanup of the
code.

Also PBUF_CHECK_FREE_OOSEQ() is now called even if there are no timeouts.
