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

This creates error objects for runtime errors that might come from the
runtime. Thus, indicating to users that the place to debug should be in
the security attributes of the container.
When creating a container with a SELinux label that doesn't exist, we
get a fairly cryptic error message:
```
$ podman run --security-opt label=type:my_container.process -it fedora bash
Error: OCI runtime error: write file `/proc/thread-self/attr/exec`: Invalid argument
```
This instead handles any errors coming from LSM's `/proc` API and
enhances the error message with a relevant indicator that it's related
to the container's security attributes.
A sample run looks as follows:
```
$ bin/podman run --security-opt label=type:my_container.process -it fedora bash
Error: `/proc/thread-self/attr/exec`: OCI runtime error: unable to assign security attribute
```
With `debug` log level enabled it would be:
```
Error: write file `/proc/thread-self/attr/exec`: Invalid argument: OCI runtime error: unable to assign security attribute
```
Note that these errors wrap ErrOCIRuntime, so it's still possible to to
compare these errors with `errors.Is/errors.As`.
One advantage of this approach is that we could start handling these
errors in a more efficient manner in the future.
e.g. If a SELinux label doesn't exist (yet), we could retry until it
becomes available.

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].

Two areas needed tweaking to accomplish this: port parsing and
binding ports on the host.
Parsing is an obvious problem - we have to accomodate an IPv6
address enclosed by [] as well as a normal IPv4 address. It was
slightly complicated by the fact that we previously just counted
the number of colons in the whole port definition (a thousand
curses on whoever in the IPv6 standard body decided to reuse
colons for address separators), but did not end up being that
bad.
Libpod also (optionally) binds ports on the host to prevent their
reuse by host processes. This code was IPv4 only for TCP, and
bound to both for UDP (which I'm fairly certain is not correct,
and has been adjusted). This just needed protocols adjusted to
read "tcp4"/"tcp6" and "udp4"/"udp6" based on what we wanted to
bind to.

do not change the runtime error to be lowercase, but use a case
insensitive regex matching. In this way the original error from the
OCI runtime is reported back.

when parsing the OCI error, be sure to discard any other output that
is not matched. The full output is still printed with
--log-level=debug.

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.

For future work, we need multiple implementations of the OCI
runtime, not just a Conmon-wrapped runtime matching the runc CLI.
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).
