Support for this has stalled in the swarmkit project due to lack of maintainer
time to review and support and the existing code no longer works with the
version of containerd used in linuxkit.

This commits an initial version of the Memorizer tracing tool. It collects and
outputs detailed data on the objects (traced from kmalloc/kmem_cache_alloc) and
accesses, tracking the context of each event with respect to thread ID, program
counter, and for allocations name of process.

This is just a direct import of the current kernel/ directory, with a
slight splitting up of the dockerfiles to build a kernel-source and kernel
image.

With redis-os and README documentation moved elsewhere,
the demo directory only contains the etcd demo setup.
Rename it.

Adds a logging daemon that collects logs in a ring buffer in a runc container.
The tools logwrite and logread can be used to read/write logs. The logging
daemon can be sent open file descriptors that will be read and included
in the logs.
Modifies init to start the daemon and use logwrite to capture logs from runc.

This is based on https://github.com/docker/swarmkit/pull/1965 which adds a
direct containerd executor to swarmkit. It is very much a work in progress.
With a suitable moby image (such as projects/swarmd/swarmd.yml) something like
this should work:
runc exec swarmd swarmctl service create --image docker.io/library/nginx:alpine --name nginx
runc exec swarmd swarmctl service ls

The ebpf packages were somewhat neglected during the restructuring of the
the repository and currently do not build. They were also a little awkward
to use. So move them to ./projects for now until it matures.
