    job control: rename signal->group_stop and flags to jobctl and update them · a8f072c1
    Tejun Heo authored
    signal->group_stop currently hosts mostly group stop related flags;
    however, it's gonna be used for wider purposes and the GROUP_STOP_
    flag prefix becomes confusing.  Rename signal->group_stop to
    signal->jobctl and rename all GROUP_STOP_* flags to JOBCTL_*.
    
    Bit position macros JOBCTL_*_BIT are defined and JOBCTL_* flags are
    defined in terms of them to allow using bitops later.
    
    While at it, reassign JOBCTL_TRAPPING to bit 22 to better accomodate
    future additions.
    
    This doesn't cause any functional change.
    
    -v2: JOBCTL_*_BIT macros added as suggested by Linus.
