This doesn't exist with newer ctr or in systems where service containers are
not started using the ctr tool. All it contains today are the stdio FIFOs,
which are not in general useful to access after container creation.

- Use 'flags' for the subcommand FlagSet
- Use %v to print errors
- Use 'path' for the path
- Fix cases where the 'path' refers to a different directory
- Don't use CamelCase for command line options

The new init adds the usermode helper which is needed with
the soon to be pushed new 4.11 kernel update.

vpnkit-expose-port is the dockerd userland proxy used to expose
forwarding ports with vpnkit. This adds the binary to the image in
/usr/bin/vpnkit-expose-port, but does not enable it by default.

The binary is used in tandem with CONFIG_STATIC_USERMODEHELPER=y in 4.11+,
see the big comment in the binary for the current whitelist of binaries.

Extract the perf binary from the kernel package and create
a new perf package for each kernel. The perf package uses the
same tags as the kernel package and only contains the perf
binary under /usr/bin. The perf package can be added to the
init section or included as a stage in a multi-stage build
for other packages.

The perf utility is somewhat kernel specific so might as well
compile it when we compile the kernel. The resulting binary
is statically linked (and stripped for size) and is added the
resulting kernel packages.
Although we add alpine packages such as libunwind and other,
it seems that the config detection code for perf/tools does
not detect them.

This cherry-picks 120010cb1eea151d38a3e66f5ffc79a0c3110292 ("tools build:
Add test for sched_getcpu()") which replaces a #ifdef based test with
a proper test for the sched_getcpu() function. The macro based condition
does not work on Alpine as it is conditional on GLIBC.
For 4.9 the cherry-pick needed some manual adjustment and also required
commit ef2c3e76d98dfb69a46d870b47656e8e5bac6e2b ("perf jit: Avoid returning
garbage for a ret variable")

Instead of figuring out which config files to use inside of makeconfig.sh,
let's figure that out in the Dockerfile and pass them into the script.

Instead of having a special case sed script, we can just put this in the
.debug config file, and have a special case when it's being checked.

Let's use the kernel machine architecture for this value.
Also remove a broken check. The "arch" binary on OSX outputs different
stuff than on linux. Since we don't need this check anyway (the variable
is mostly to demonstrate how cross platform stuff would work, not to
actually do it yet), let's just remove the check.

mdev only supports hot-plug, ie devices which are added
after the kernel booted. For cold-plugged devices, ie devices
present when the kernel boots, we need to modprobe the drivers
differently. The additions to rc.init does just that.
