enable gocritic linter
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.

use libnetwork from c/common
The libpod/network packages were moved to c/common so that buildah can
use it as well. To prevent duplication use it in podman as well and
remove it from here.

Moritz "WanzenBug" Wanzenböck 5df883e87d bindings: reuse context for API requests
One of the main uses of context.Context is to provide cancellation for
go-routines, including API requests. While all user-facing bindings
already used a context parameter, it was only used to pass the client
information around.

This commit changes the internal DoRequest wrapper to take an additional
context argument, and pass that to the http request. Previously, the context
was derived from context.Background(), which made it impossible to cancel
once started.

All the convenience wrappers already supported the context parameter, so the
only user facing change is that cancelling those context now works as one
would expect.

Wire network interface into libpod
Make use of the new network interface in libpod.

This commit contains several breaking changes:
- podman network create only outputs the new network name and not file
  path.
- podman network ls shows the network driver instead of the cni version
  and plugins.
- podman network inspect outputs the new network struct and not the cni
  conflist.
- The bindings and libpod api endpoints have been changed to use the new
  network structure.

The container network status is stored in a new field in the state. The
status should be received with the new `c.getNetworkStatus`. This will
migrate the old status to the new format. Therefore old containers should
contine to work correctly in all cases even when network connect/
disconnect is used.

New features:
- podman network reload keeps the ip and mac for more than one network.
- podman container restore keeps the ip and mac for more than one
  network.
- The network create compat endpoint can now use more than one ipam
  config.

The man pages and the swagger doc are updated to reflect the latest
changes.

Paul Holzinger 8494bcb866 podman network label support
Add label support for podman network create. Use the `args`
field in the cni config file to store the podman labels.
Use `podman_labels` as key name and store the labels as
map[string]string.

For reference: https://github.com/containernetworking/cni/blob/master/CONVENTIONS.md#args-in-network-config
https://github.com/containernetworking/cni/blob/spec-v0.4.0/SPEC.md#network-configuration

Example snippet:

```
...
"args": {
	"podman_labels": {
		"key1":"value1",
		"key2":"value2"
	}
}
...
```

Make podman network list support several filters. Supported filters are name,
plugin, driver and label. Filters with different keys work exclusive. Several label
filters work exclusive and the other filter keys are working inclusive.

Also adjust the compat api to support labels in network create and list.

Breaking changes:

- podman network ls -f shortform is used for --filter instead --format
This matches docker and other podman commands (container ps, volume ps)

- libpod network list endpoint filter parameter is removed. Instead the
filters paramter should be used as json encoded map[string][]string.

baude a3e0b7d117 add network connect|disconnect compat endpoints
this enables the ability to connect and disconnect a container from a
given network. it is only for the compatibility layer. some code had to
be refactored to avoid circular imports.

additionally, tests are being deferred temporarily due to some
incompatibility/bug in either docker-py or our stack.

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].

Valentin Rothberg dc80267b59 compat handlers: add X-Registry-Auth header support
* Support the `X-Registry-Auth` http-request header.

 * The content of the header is a base64 encoded JSON payload which can
   either be a single auth config or a map of auth configs (user+pw or
   token) with the corresponding registries being the keys.  Vanilla
   Docker, projectatomic Docker and the bindings are transparantly
   supported.

 * Add a hidden `--registries-conf` flag.  Buildah exposes the same
   flag, mostly for testing purposes.

 * Do all credential parsing in the client (i.e., `cmd/podman`) pass
   the username and password in the backend instead of unparsed
   credentials.

 * Add a `pkg/auth` which handles most of the heavy lifting.

 * Go through the authentication-handling code of most commands, bindings
   and endpoints.  Migrate them to the new code and fix issues as seen.
   A final evaluation and more tests is still required *after* this
   change.

 * The manifest-push endpoint is missing certain parameters and should
   use the ABI function instead.  Adding auth-support isn't really
   possible without these parts working.

 * The container commands and endpoints (i.e., create and run) have not
   been changed yet.  The APIs don't yet account for the authfile.

 * Add authentication tests to `pkg/bindings`.

Brent Baude 54587335be [CI:DOCS]Binding overhauls
Add binding for networks and begin documentation for binding methods for godoc.  Also, add major functions to their own subpackages so reduce the amount of of method confusion.  So instead of: bindings.ListImages(), we now do a [bindings].images.List().

Also, the connection is passed to each binding method via a context to allow for future growth.

Lastly, add first set of tests.  There are a couple of things to work out for rootless tests yet.
