Matthew Heon 689329f749 Ensure volumes reacquire locks on state refresh
After a restart, pods and containers both run a refresh()
function to prepare to run after a reboot. Until now, volumes
have not had a similar function, because they had no per-boot
setup to perform.

Unfortunately, this was not noticed when in-memory locking was
introduced to volumes. The refresh() routine is, among other
things, responsible for ensuring that locks are reserved after a
reboot, ensuring they cannot be taken by a freshly-created
container, pod, or volume. If this reservation is not done, we
can end up with two objects using the same lock, potentially
needing to lock each other for some operations - classic recipe
for deadlocks.

Add a refresh() function to volumes to perform lock reservation
and ensure it is called as part of overall refresh().

Valentin Rothberg 11c282ab02 add libpod/config
Refactor the `RuntimeConfig` along with related code from libpod into
libpod/config.  Note that this is a first step of consolidating code
into more coherent packages to make the code more maintainable and less
prone to regressions on the long runs.

Some libpod definitions were moved to `libpod/define` to resolve
circular dependencies.

Matthew Heon feba94eb95 Migrate can move containers to a new runtime
This is a horrible hack to work around issues with Fedora 31, but
other distros might need it to, so we'll move it upstream.

I do not recommend this functionality for general use, and the

upgrade cases, it will be the only thing that allows for a
working system.

For future work, we need multiple implementations of the OCI

As part of this, do some refactoring on the interface for exec
(move to a struct, not a massive list of arguments). Also, add
'all' support to Kill and Stop (supported by runc and used a bit
internally for removing containers).

will use compiled-in defaults. However, it won't tell us this via

c/storage, in a bad spot).

paths for core parts of libpod.

Matthew Heon 5fb4feb36a Fix a segfault on Podman no-store commands with refresh
When a command (like `ps`) requests no store be created, but also
requires a refresh be performed, we have to ignore its request

storage service. Without the storage service, Podman will still
segfault. Fix that oversight here.

system: add new subcommand "migrate"
it is useful to migrate existing containers to a new version of
podman.  Currently, it is needed to migrate rootless containers that
were created with podman <= 1.2 to a newer version which requires all
containers to be running in the same user namespace.

baude 7bf7c177ab journald event logging
add the ability for podman to read and write events to journald instead
of just a logfile.  This can be controlled in libpod.conf with the
`events_logger` attribute of `journald` or `file`.  The default will be
set to `journald`.

rootless: fix segfault on refresh if there are containers

rootless: use a single user namespace
simplify the rootless implementation to use a single user namespace
for all the running containers.

This makes the rootless implementation behave more like root Podman,
where each container is created in the host environment.

There are multiple advantages to it: 1) much simpler implementation as
there is only one namespace to join.  2) we can join namespaces owned
by different containers.  3) commands like ps won't be limited to what
container they can access as previously we either had access to the
storage from a new namespace or access to /proc when running from the
host.  4) rootless varlink works.  5) there are only two ways to enter
in a namespace, either by creating a new one if no containers are
running or joining the existing one from any container.

Containers created by older Podman versions must be restarted.

Matthew Heon 5ed62991dc Remove ulele/deepcopier in favor of JSON deep copy
We have a very high performance JSON library that doesn't need to
perform code generation. Let's use it instead of our questionably
performant, reflection-dependent deep copy library.

Most changes because some functions can now return errors.

Also converts cmd/podman to use jsoniter, instead of pkg/json,
for increased performance.

utils: split generation and writing of storage.conf
split the generation for the default storage.conf and when we write it
if not existing for a rootless user.

This is necessary because during the startup we might be overriding
the default configuration through --storage-driver and --storage-opt,
that would not be written down to the storage.conf file we generated.

baude ca1e76ff63 Add event logging to libpod, even display to podman
In lipod, we now log major events that occurr.  These events
can be displayed using the `podman events` command. Each
event contains:

* Type (container, image, volume, pod...)
* Status (create, rm, stop, kill, ....)
* Timestamp in RFC3339Nano format
* Name (if applicable)
* Image (if applicable)

The format of the event and the varlink endpoint are to not
be considered stable until cockpit has done its enablement.
