Now that sys_sysctl is a generic wrapper around /proc/sys .ctl_name
and .strategy members of sysctl tables are dead code. Remove them.
Remove a smattering of ctl_names used in sysctl paths,
and kill the ctl_names in the recently added mach-bcmring.
mach-bcmring never should have had sysctl entries with
.ctl_name set. The binary sysctl interface has been frozen
for a long time before that code was merged, to prevent
probmes with conflicts and lack of testing. The sysctl_check
code would have caught this if anyone had ever tested it that way.
So I have simply dropped the binary sysctl support instead of
adding another compat entry into sysctl_binary.c. Going through
/proc/sys/reboot/warm will still work.

Also add an C99 named initializer to the child member of unaligned_root

The deleted strategy routines here surprise me. ctl_name was

Looking at the arlan code it appears all of the sysctl
entries are disabled debug code, and have not been enabled
since the driver was merged in feb of 2003.
Since except for a select few that userspace can't
get along without the binary sysctl table entries
are going away. Kill the unused arlan binary sysctls.

A malicious user could have passed in a ctl_name of 0 and triggered
the well know ctl_name to procname mapping code, instead of the wild
card matching code. This is a slight problem as wild card entries don't
have procnames, and because in some alternate universe a network device
might have ifindex 0. So test for and handle wild card entries first.

dev_get_by_index does not exist when the network stack is not
compiled in, so only include the code to follow wild card paths
when the network stack is present.
I have shuffled the code around a little to make it clear
that dev_put is called after dev_get_by_index showing that
there is no leak.

The ctl_name and strategy fields are unused, now that sys_sysctl
is a compatibility wrapper around /proc/sys. No longer looking
at them in the generic code is effectively what we are doing
now and provides the guarantee that during further cleanups
we can just remove references to those fields and everything
will work ok.

Now that the sys_sysctl is now a compatibility wrapper around
/proc/sys we can remove much of sysctl_check and reduce it
to a few remaining sanity checks. This completely decouples
it from the binary sysctl system call.
Little things like ensuring that the sysctl has not already
been registered are all that remain.

Now that sys_sysctl is a compatibility layer on top of /proc/sys
these routines are never called but are still put in sysctl

To simply maintenance and to be able to remove all of the binary
sysctl support from various subsystems I have rewritten the binary
sysctl code as a compatibility wrapper around proc/sys.
The code is built around a hard coded table based on the table
in sysctl_check.c that lists all of our current binary sysctls
and provides enough information to convert from the sysctl
binary input into into ascii and back again. New in this
patch is the realization that the only dynamic entries
that need to be handled have ifname as the asscii string
and ifindex as their ctl_name.
When a sys_sysctl is called the code now looks in the
translation table converting the binary name to the
path under /proc where the value is to be found. Opens
that file, and calls into a format conversion wrapper
that calls fop->read and then fop->write as appropriate.
Since in practice the practically no one uses or tests
sys_sysctl rewritting the code to be beautiful is a little
silly. The redeeming merit of this work is it allows us to
rip out all of the binary sysctl syscall support from
everywhere else in the tree. Allowing us to remove
a lot of dead (after this patch) and barely maintained code.
In addition it becomes much easier to optimize the sysctl
implementation for being the backing store of /proc/sys,
without having to worry about sys_sysctl.
