pkg: switch to golang native error wrapping
We now use the golang error wrapping format specifier `%w` instead of
the deprecated github.com/pkg/errors package.

cdoern 2792e598c7 podman cgroup enhancement
currently, setting any sort of resource limit in a pod does nothing. With the newly refactored creation process in c/common, podman ca now set resources at a pod level
meaning that resource related flags can now be exposed to podman pod create.

cgroupfs and systemd are both supported with varying completion. cgroupfs is a much simpler process and one that is virtually complete for all resource types, the flags now just need to be added. systemd on the other hand
has to be handeled via the dbus api meaning that the limits need to be passed as recognized properties to systemd. The properties added so far are the ones that podman pod create supports as well as `cpuset-mems` as this will
be the next flag I work on.

* Replace "setup", "lookup", "cleanup", "backup" with
  "set up", "look up", "clean up", "back up"
  when used as verbs. Replace also variations of those.

* Improve language in a few places.

api: show the memory limit specified for the container
use the memory limit specified for the container instead of reading it
from the cgroup.  It is not reliable to read it from the cgroup since
the container could have been moved to a different cgroup and in
general the OCI runtime might create a sub-cgroup (like crun does).

Closes: https://github.com/containers/podman/issues/14676

Jake Correnti 608ad7d113 Non-running containers now report statistics via the `podman stats`
command

Previously, if a container was not running, and the user ran the `podman
stats` command, an error would be reported: `Error: container state
improper`.

Podman now reports stats as the fields' default values for their
respective type if the container is not running:

```
$ podman stats --no-stream demo

ID            NAME        CPU %       MEM USAGE / LIMIT  MEM %       NET IO      BLOCK IO    PIDS        CPU TIME    AVG CPU %
4b4bf8ce84ed  demo        0.00%       0B / 0B            0.00%       0B / 0B     0B / 0B     0           0s          0.00%
```

Closes: #14498

podman stats: calc CPU percentage correctly
When you run podman stats, the first interval always shows the wrong cpu
usage. To calculate cpu percentage we get the cpu time from the cgroup
and compare this against the system time between two stats. Since the
first time we do not have a previous stats an empty struct is used
instead. Thus we do not use the actual running time of the container but
the current unix timestamp (time since Jan 1 1970).

To fix this we make sure that the previous stats time is set to the
container start time, when it is empty.

[NO NEW TESTS NEEDED] No idea how I could create a test which would have
a predictable cpu usage.

See the linked bugzilla for a reproducer.

Jhon Honce deaf969243 Refacter API server emphasis on logging
* To aid in debugging log API request and response bodies at trace
  level. Events can be correlated using the X-Reference-Id.
* Server now echos X-Reference-Id from client if set, otherwise
  generates an unique id.
* Move logic for X-Reference-Id into middleware
* Change uses of Header.Add() to Set() when setting Content-Type
* Log API operations in Apache format using gorilla middleware
* Port server code to use BaseContext and ConnContext

Valentin Rothberg 8489dc4345 move go module to v2
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].
