        src/sys/conf: param.c
        src/sys/kern: kern_lwp.c kern_proc.c kern_prot.c kern_resource.c
            kern_uidinfo.c
        src/sys/sys: lwp.h resource.h sysctl.h uidinfo.h

Log Message:
Add a new resource to limit the number of lwps per user, RLIMIT_NTHR. There
is a global sysctl kern.maxlwp to control this, which is by default 2048.
The first lwp of each process or kernel threads are not counted against the
limit. To show the current resource usage per user, I added a new sysctl
that dumps the uidinfo structure fields.
