We missed bumping the go module, so let's do it now :)
* Automated go code with github.com/sirkon/go-imports-rename
* Manually via `vgrep podman/v2` the rest

Convert the existing network aliases set/remove code to network
connect and disconnect. We can no longer modify aliases for an
existing network, but we can add and remove entire networks. As
part of this, we need to add a new function to retrieve current
aliases the container is connected to (we had a table for this
as of the first aliases PR, but it was not externally exposed).
At the same time, remove all deconflicting logic for aliases.
Docker does absolutely no checks of this nature, and allows two
containers to have the same aliases, aliases that conflict with
container names, etc - it's just left to DNS to return all the
IP addresses, and presumably we round-robin from there? Most
tests for the existing code had to be removed because of this.
Convert all uses of the old container config.Networks field,
which previously included all networks in the container, to use
the new DB table. This ensures we actually get an up-to-date list
of in-use networks. Also, add network aliases to the output of
`podman inspect`.

As part of this, we need two new functions, for retrieving all
aliases for a network and removing all aliases for a network,
both required to test.
Also, rework handling for some things the tests discovered were
broken (notably conflicts between container name and existing
aliases).

This was inspired by https://github.com/cri-o/cri-o/pull/3934 and
much of the logic for it is contained there. However, in brief,
a named return called "err" can cause lots of code confusion and
encourages using the wrong err variable in defer statements,
which can make them work incorrectly. Using a separate name which
is not used elsewhere makes it very clear what the defer should
be doing.
As part of this, remove a large number of named returns that were
not used anywhere. Most of them were once needed, but are no
longer necessary after previous refactors (but were accidentally
retained).

With the advent of Podman 2.0.0 we crossed the magical barrier of go
modules. While we were able to continue importing all packages inside
of the project, the project could not be vendored anymore from the
outside.
Move the go module to new major version and change all imports to
`github.com/containers/libpod/v2`. The renaming of the imports
was done via `gomove` [1].

Include the unit tests (i.e., _test.go files) for linting to make the
tests more robust and enforce the linters' coding styles etc.

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.

Add ability to evict a container when it becomes unusable. This may
happen when the host setup changes after a container creation, making it
impossible for that container to be used or removed.
Evicting a container is done using the `rm --force` command.

During an earlier bugfix, we swapped all instances of
ContainerConfig to Config, which was meant to fix some data we
were returning from Inspect. This unfortunately also renamed a
libpod internal struct for container configs. Undo the rename
here.

Instead of storing the runtime's file lock dir in the BoltDB
state, refer to the runtime inside the Bolt state instead, and
use the path stored in the runtime.
This is necessary since we moved DB initialization very far up in
runtime init, before the locks dir is properly initialized (and
it must happen before the locks dir can be created, as we use the
DB to retrieve the proper path for the locks dir now).

Ensure we don't break the unit tests by creating a locks
directory (which, prior to the last commit, would be created by
BoltDB state init).

Pod and container State structs are now allowed to be empty on
first being retrieved from the database. Rework pod and container
equality functions used in testing to account for this change.

Dependency containers must be in the same namespace, to ensure
there are never problems resolving a dependency.

Add basic awareness of namespaces to the database. As part of
this, add constraints so containers can only be added to pods in
the same namespace.

Containers in pods cannot depend on containers outside of the
same pod. Make the reverse true as well - containers not in pods
cannot depend on containers in pods. This greatly simplifies our
dependency handling, as we can guarantee that removing a pod will
not encounter dependency issues.

The SQLite DB backend has become an unmanageable nightmare. I
like having the option for DB work, but it's become an active
hindrance to further development, and it's definitely not in any
shape to be actively used.

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.

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.
