    libps (_proc_stat_free): Fix memory leak
    
    The thread_waits field was never freed; this change adds the code to do
    so if the corresponding flag is set.
    
    Users are also warned of the consequences, namely, that they should not
    free process proc_stats before all their associated thread ones are
    gone, since the latter may reference the former's thread_waits field.
    However, with the normal interface (ie.  ps_context_free), all
    proc_stats are freed at once, so this is not an issue.
    
    * libps/procstat.c (_proc_stat_free): Free ps->thread_waits if
    PSTAT_THREAD_WAITS flag is set.
    * libps/ps.h (_proc_stat_free): Document that thread proc_stats must be
    freed before process proc_stat can be.
