We previously enforced this for security reasons, but as Dan has
explained on several occasions, it's not very valuable there
(it's trivially easy to bypass) and it does seriously annoy folks
trying to use named volumes. Flip the default from 'on' to 'off'.

The cleanup command creation logic is made public as part of this
and wired such that we can call it both within SpecGen (to make
container exit commands) and from the ABI detached exec handler.
Exit commands are presently only used for detached exec, but
theoretically could be turned on for all exec sessions if we
wanted (I'm declining to do this because of potential overhead).
I also forgot to copy the exit command from the exec config into
the ExecOptions struct used by the OCI runtime, so it was not
being added.
There are also two significant bugfixes for exec in here. One is
for updating the status of running exec sessions - this was
always failing as I had coded it to remove the exit file *before*
reading it, instead of after (oops). The second was that removing
a running exec session would always fail because I inverted the
check to see if it was running.

We need to be able to use cleanup processes to remove exec
sessions as part of detached exec. This PR adds that ability. A
new flag is added to `podman container cleanup`, `--exec`, to
specify an exec session to be cleaned up.
As part of this, ensure that `ExecCleanup` can clean up exec
sessions that were running, but have since exited. This ensures
that we can come back to an exec session that was running but has
since stopped, and clean it up.

Add a new ContainerEngine method for creating a detached exec
session, and wire in the frontend code to do this. As part of
this, move Streams out of ExecOptions to the function signature
in an effort to share the struct between both methods.

* Update blang/semver to allow ParseTolerant() support
* Provide helper functions for API handlers to obtain client's 'version'
path variable focused on API endpoint tree: libpod vs. compat
* Introduce new errors:
* version not given in path, endpoints may determine if this is a hard
error (ErrVersionNotGiven)
* given version not supported (ErrVersionNotSupported), only a soft
error if the handler is going to hijack the connection
* Added unit tests for version parsing
* bindings check version on connect:
* client <= Server API version connection is continued
* client >= Server API version connection fails

To terminate a connection of varlink, say after sending a file, we need to send a message containing a delimiter of ':' so the client knows to hang up.

Most importantly, note the pruning behavior of compat Inspect.
Less importantly, note that the Tty parameter to Start is only
ignored, as opposed to being not supported.

The usual flow for exec is going to be:
- Create exec session
- Start and attach to exec session
- Exec session exits, attach session terminates
- Client does an exec inspect to pick up exit code
The safest point to remove the exec session, without doing any
database changes to track stale sessions, is to remove during the
last part of this - the single inspect after the exec session
exits.
This is definitely different from Docker (which would retain the
exec session for up to 10 minutes after it exits, where we will
immediately discard) but should be close enough to be not
noticeable in regular usage.

The pkg/network/files.go methods currently use the constant '/etc/cni/net.d'
for network handling. This results in the unability of podman-network-inspect
and podman-network-rm to locate the cni network configuration files.
This commit propagates the libpod.Runtime through the networking methods and
finally makes use of its configuration (config.Network.NetworkConfigDir).
