iostat(8) and systat(8) support for separate read/write disk statistics.
"iostat -x" now shows these (ala linux/solaris), but this is only splitting
the read/write bytes/transactions, not adding any new metrics. "systat

sort of like VMS' "MONITOR ALL"-command.

Code was submitted by Jarkko Teppo <jate@uwasa.fi> in PR 10851,

G/C function used in old command parsing

Two things:

1.) fix a bug which caused coredumps when starting with no mode arguments
2.) move to table-lookup for mode-specific command parsing as well.
all command matching is now table-driven.

End special-casing of `start' and `interval' global commands.
Vastly simplify handling of mode switches, and short-syntax interval
changes. Substring matching of mode names and commands will come
shortly, however the previous method of substring matching modes (it was
not available for commands) is currently not working.

TODO: implement table lookups for mode-specific commands.

Handle arguments to global commands. Note that the `interval' and
`start' global commands are still special cased, which will change

Rototill global command matching -- switch from ad-hoc tomfoolery to a
table lookup. This will make prefix matching and so on easier.

Expect a similar change for mode-specific commands before too long.

While there, rename some structures with misleading names.

Watch this space for more changes soon.

- Add `bufcache' display which shows buffer cache usage per filesystem,
ala the monitor(1) command for Ultrix.
- Allow `h' or `?' to show the command list (same as `:help').
- Sort commands in cmdtab.c and systat.1

branches: 1.10.4;

view is identical to the output of `ps aux' except that a.) the RSS and VSZ

Fix handling of privileges - the gid was given up before dkinit()
was called.
Pass the gid to use for KVM access explicitely to dkinit(), the caller
decides whether to call setgid(getgid()) or not.
