History
Jung-uk Kim e6c006d96a Improve PCB flags handling and make it more robust. Add two new functions 
for manipulating pcb_flags.  These inline functions are very similar to
atomic_set_char(9) and atomic_clear_char(9) but without unnecessary LOCK
prefix for SMP.  Add comments about the rationale[1].  Use these functions
wherever possible.  Although there are some places where it is not strictly
necessary (e.g., a PCB is copied to create a new PCB), it is done across
the board for sake of consistency.  Turn pcb_full_iret into a PCB flag as
it is safe now.  Move rarely used fields before pcb_flags and reduce size
of pcb_flags to one byte.  Fix some style(9) nits in pcb.h while I am in
the neighborhood.
