Instead of implementing refcounts at each graphdriver, implement this in
the layer package which is what the engine actually interacts with now.
This means interacting directly with the graphdriver is no longer
explicitly safe with regard to Get/Put calls being refcounted.
In addition, with the containerd, layers may still be mounted after
a daemon restart since we will no longer explicitly kill containers when
we shutdown or startup engine.
Because of this ref counts would need to be repopulated.

When a plugin is first found, it is loaded into the available plugins
even though it's not activated yet.
If activation fails it is taken out of the list.
While it is in the list, other callers may see it and try to check it's
manifest. If it is not fully activated yet, the manifest will be nil and
cause a panic.
This is especially problematic for drivers that are down and have not
been activated yet.
We could just not load the plugin into the available list until it's
fully active, however that will just cause multiple of the same plugin
to attemp to be loaded.
We could check if the manifest is nil and return early (instead of
panicing on a nil manifest), but this will cause a 2nd caller to receive
a response while the first caller is still waiting, which can be
awkward.
This change uses a condition variable to handle activation (instead of
sync.Once). If the plugin is not activated, callers will all wait until
it is activated and receive a broadcast from the condition variable
signaling that it's ok to proceed, in which case we'll check if their
was an error in activation and proceed accordingly.

This fix tries to fix Docker core dumps when removing network with special
characters. The issue is from the fact that when docker client tries to
pass the command to API, the networkID is not escaped in case of special
characters. This also means other commands (not just `docker network rm`)
may face the same issue (e.g., `docker network connect`).
This fix adds the URL path escape to properly handle it. In addition, an
integration test for network create and delete is added to cover the cases
in #21401.
This fix fixes#21401.

Removes the seccomp buildtag when building runc.
Because seccomp isn't currently being built, this would cause
the build to fail.
