Add bf_window_linear option to SchedulerParameters

This patch should be identified as having an author
Gary B Skouson <Gary.Skouson@pnnl.gov>

Add new SchedulerParameters option bf_window_linear to control the rate at
    which the backfill test window expands. This can be used on a system with
    a modest number of running jobs (hundreds of jobs) to help prevent expected
    start times of pending jobs to get pushed forward in time. On systems with
    large numbers of running jobs, performance of the backfill scheduler will
    suffer and fewer jobs will be evaluated.

OK, this is committed da4149318a45c, only minor changes. (fatal instead of error, and if it was set and then was removed it resets the static variable.
