Read pstatus info from /proc

Browse Source 
* glibtop_private.h, procdata.c (glibtop_get_proc_signal_s):
        Read pstatus info from /proc

        * procsignal.c (glibtop_get_proc_signal_s): Implemented
        set of pending and blocked signals. The rest should probably
        be read from /proc/<pid>/sigact, but I'm not sure it's
        worth implementing before thread API comes into place.

        * siglist.c: Added Solaris 7 signals. Someone will gettextize
        it eventually. Besides, signal list should become a pointer
        instead of being fixed field. We need some run time initializations.
        The code is written, but commented out.
