opcontrol is now dropped and replaced with the operf interface. As such, we drop
the opstart/opstop commands and any patches related to the old removed interfaces.
Some patches were also mered upstream so those are also dropped.
There is also a problem found on mips with the security flags enabled, the
patch has more specific details.
