pTools Process flag reporting utility (pflags)

Based off the Sun Microsystems pflags utility.  Reports various
flags for each process (light weight process in the solaris case).
Information such as data_model, global process flags, current system
call waiting in, signal mask etc.

Usage:
	pflags pid ...

NOTES:
	-r flags could be implemented by re-evaluating the pstop command.

	The signal and fault tracing parts (ala PCSTRACE & PCSFAULT) of 
		the Solaris pflags command are not implemented because 
		this _feature_ does not exist yet in the Linux kernel yet.

	The system call entry and exit parts (ala PCSENTRY & PCSEXIT) of
		the Solaris pflags command are not implemented either
		because they do not exist in the Linux kernel yet.
