It makes little sense to create a log line string from the entry just to
parse it again into a LogLine. We have the typed fields so we can
assemble the logLine direclty, this makes things simpler and more
efficient.
Also entries from the passthrough driver do not use the CONTAINER_ID_FULL
field, instead we can just access c.ID() directly.

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

The linter ensures a common code style.
- use switch/case instead of else if
- use if instead of switch/case for single case statement
- add space between comment and text
- detect the use of defer with os.Exit()
- use short form var += "..." instead of var = var + "..."
- detect problems with append()
```
newSlice := append(orgSlice, val)
```
This could lead to nasty bugs because the orgSlice will be changed in
place if it has enough capacity too hold the new elements. Thus we
newSlice might not be a copy.
Of course most of the changes are just cosmetic and do not cause any
logic errors but I think it is a good idea to enforce a common style.
This should help maintainability.

The hpcloud is not maintained anymore. nxadm is already part of the
dependency chain, so it won't add work for downstream packages.
While testing upcoming changes to the events-file backend, I noticed
that nxadm is shipping required fixes.

In libpod/logs.LogLine.Write(), don't write a newline to stdout/stderr
when the log message is only part of a line.
In libpod.ConmonOCIRuntime.HTTPAttach(), don't send a newline over the
HTTP connection when the log message is only part of a line.
In pkg/api/handlers/compat.LogsFromContainer(), don't send a newline
over the HTTP connection when the log message is only part of a line,
and don't make doing so conditional on whether or not the client used
the docker or podman endpoint.
In pkg/domain/infra/tunnel.ContainerEngine.ContainerLogs(), don't add
our own newline to log messages, since they already come through from
the server when they need to.

The initial version of libimage changed the order of layers which has
now been restored to remain backwards compatible.
Further changes:
* Fix a bug in the journald logging which requires to strip trailing
new lines from the message. The system tests did not pass due to
empty new lines. Triggered by changing the default logger to
journald in containers/common.
* Fix another bug in the journald logging which embedded the container
ID inside the message rather than the specifid field. That surfaced
in a preceeding whitespace of each log line which broke the system
tests.
* Alter the system tests to make sure that the k8s-file and the
journald logging drivers are executed.
* A number of e2e tests have been changed to force the k8s-file driver
to make them pass when running inside a root container.
* Increase the timeout in a kill test which seems to take longer now.
Reasons are unknown. Tests passed earlier and no signal-related
changes happend. It may be CI VM flake since some system tests but
other flaked.

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

Make the ContainerLogsOptions support two io.Writers,
one for stdout and the other for stderr. The logline already
includes the information to which Writer it has to be written.

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].

in cases where the log file exceeds the available memory of a system, we had a bug that triggered an oom because the entire logfile was being read when the tail parameter was given. this reads in chunks and is more or less memory safe.
