Support of xl sched-sedf
Supports the xl subcommand sched-sedf.
The man page is only a minimal version (copy from xm man page without
examples). BTW: the xm man page seems not to be in sync with xm sched-sedf -h
regarding the time units. I used milliseconds in the xl implementation.
Only minimal semantical checks of parameters.
