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.

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.

- Update VMBus lockup patch (0009) based on the one submitted to LKML
- 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)
- The latter required cherry-picking 0010 and 0011

- 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.

Move to the development track of `containerd` not the legacy 0.2
branch. The commands have changed a bit.
This does increase the image size as we are bundling the Docker
copy and our copy, and the new one is larger as it is growing features.
Hopefully Docker will shrink eventually. Also we may replace `ctr`
with a library.

Add basic database setup for AWS, GCP although these are not yet used
by the setup code but will be useful later.
Currently each is gated by `mobyplatform` but this can be removed once we
construct Moby per platform, and once these are containerised so they
are not run from `openrc`.

Previously we allocated `sizeof(struct ring) + size`. This patch
allocates `sizeof(struct ring)` and then `size` for the payload
separately. Hopefully the payload will be better aligned.
