After freeing the head of the perfstat block list, we must set it to NULL
to indicate that new blocks must be allocated. Previously, we risked
segfaults by trying to use a freed list.

- make a `bin/` directory
- make hyperkit-test pass, as it writes to pty so redirect was not working

Do not build by default, as we are not using yet.
Clean up the gitignores at the same time as they were affected.

This adds two new control channel requests, START_PERFSTAT and
STOP_PERFSTAT, that begin and end performance statistics collection
respectively. START_PERFSTAT takes the name of the mountpoint on which
to enable statistics collection and returns the current monotonic time.
STOP_PERFSTAT takes the name of the mountpoint on which to disable
statistics collection and returns the current monotonic time and the
message timings that have been collected.
Performance statistics are collected in a linked list of blocks. pthread
locks are used for synchronization.

This will potentially leave stuff in lost+found but may be able to
recover from more filesystem corruption.

This means the base system build and kernel build can be split
without dependencies, and just assembled later.

- Remove hack to forcea TimeSync protocol to version 3 (0005)
- Properly cherry-pick patch 0008 (was missing the cherry-pick reference)
- Add a new patch which properly negotiates the TimeSync protocol (0012)

- simplify the process by having the riddler container build the rootfs and config
- output tarred up rootfs and config.json as otherwise file ownership not preserved
- allow easy build of a collection of container tarballs with another conversion script
This makes it easy to choose which container images you want and just convert any
set to a initrd image
```
tar cf - container1.tar container2.tar | docker run -i tartar2initrd > initrd.img
```
Next stage will use a manifest to select the ones to add for each edition.

This is mainly for testing.
You can run with something like
```
docker run -v ~/.ssh/id_rsa.pub:/root/.ssh/authorized_keys -p 2222:22 -e TINI_SUBREAPER=1 --pid=host mobylinux/sshd:36c44542d8120e384c724a078e3e489f7a58382c
```
if you want to run in the host pid namespace. You must provide an
authorized key, you may provide a host key.
