Use whitespace (spaces and tabs) as the delimiter.
Consecutive spaces and tabs count as one single field
separator.

cmdlengthdelta is the size of the header and we were using it to
allocate a buffer to store the command line. This would mean that
the cmdbuf could be too short. In practice this was never noticed unless
you usually run top -a. On a stock FreeBSD system you can see the
problem by running sendmail and then running top -a on a big terminal
window. In practice this doubles to size available to cmdbuf since the
header is around 65-68 bytes.

userland via routing socket or sysctl. This eliminates the following
KAME-specific sin6_scope_id handling routine from each userland utility:
sin6.sin6_scope_id = ntohs(*(u_int16_t *)&sin6.sin6_addr.s6_addr[2]);
This behavior can be controlled by net.inet6.ip6.deembed_scopeid. This is
set to 1 by default (sin6_scope_id will be filled in the kernel).

- Implement a function to ensure that all preempted threads have switched
back out at least once. Use this to make sure there are no stale
references to the old ktr_buf or the lock profiling buffers before
updating them.

Machines can stall out because mbufs are low, however sometimes we won't
see "requests denied", instead we see user land processes or kernel threads
blocking waiting for mbufs because they set M_WAIT. These consumers do not
see errors, only stalling.
Unfortunately until now, netstat did not export this information
so you could have experienced an mbuf shortage and have no way of
seeing it unless you happen to run netstat at the exact time of the
shortage and see "in use" = "max".
By exporting the number of times processes are blocked, we can
effectively see how often non-interrupt context threads are effectively
"denied".

This version has more features and is better written.
I intend to submit this upstream as well.
