ce7a0171d1 Squash logged errors from failed SQL rollbacks
Currently we unconditionally roll back transactions after error,
even if a commit has already been attempted. Commit is guaranteed
to end a transaction, though, whether by successfully committing
or by rolling back if that fails. As such, we attempt a double
rollback if a transaction fails at commit (for example, for a
constraint violation), which doesn't error but does log angry
warning messages. Ensure we don't try rolling back after commit
runs to prevent this.

dc6a99df4c Containers in a pod can only join namespaces in that pod
This solves some dependency problems in the state, and makes
sense from a design standpoint.

Containers not in a pod can still depend on the namespaces of
containers joined to a pod, which we might also want to change in
the future.

4f225b47c9 Refactor Pod to use a Config struct
This allows us to JSON it and stuff it in the DB - previously,
all pod fields were private, so JSON couldn't encode them. This
allows us to keep all pod fields private by having a substruct
with public fields.

2e48c60bc5 Add DNS and security fields to DB
Also moves port mappings out of the SQL DB and into a file on
disk. These could get very sizable (hundred to thousands of
ports) so moving them out to a file will keep the DB small and
fast.

Finally, add a foreign key reference from container ID to
container state ID. This ensures we never get into an
inconsistent state where we have data in one table but not the
other.

1f49f555af Plumb through the --stop-timeout signal handling
podman run/create have the ability to set the stop timeout flag.
We need to stop it in the database.

Also Allowing negative time for stop timeout makes no sense, so switching
to timeout of uint, allows user to specify huge timeout values.
