This change adds an nvidia-ctk system create-device-nodes command for
creating NVIDIA device nodes. Currently this is limited to control devices
(nvidia-uvm, nvidia-uvm-tools, nvidia-modeset, nvidiactl).
A --dry-run mode is included for outputing commands that would be executed and
the driver root can be specified.

This change adds an nvidia-container-runtime.modes.cdi.annotation-prefixes config
option that defaults to cdi.k8s.io/. This allows the annotation prefixes parsed
for CDI devices to be overridden in cases where CDI support in container engines such
as containerd or crio need to be overridden.

This chagne prefers (non-symlink) sockets at /run over /var/run for
nvidia-persistenced and nvidia-fabricmanager sockets.

The following changes are made:
* The default-cdi-kind config option is used to convert an envvar entry to a fully-qualified device name
* If annotation devices exist, these are used instead of the envvar devices.
* The `all` device is no longer treated as a special case and MUST exist in the CDI spec.

This change copies dxcore.h and dxcore.c from libnvidia-container to
allow for the driver store path to be queried. Modifications are made
to dxcore to remove the code associated with checking the components
in the driver store path.

This change ensures that the update-ldcache hook is created in a manner
consistent with other nvidia-ctk hooks ensuring that a full path is
used.
Without this change the update-ldcache hook on Tegra-based sytems had an
invalid path.

If this is not done, the default config which sets the nvidia-ctk.path
option as "nvidia-ctk" will result in an invalid OCI spec if a hook is
injected. This change ensures that the path used is always an absolute
path as required by the hook spec.

This change ensures that the first match of an executable in the path
is retured instead of a list of candidates. This prevents a CDI spec,
for example, from containing multiple entries for a single executable
(e.g. nvidia-smi).

This change adds an --nvidia-ctk-path to the nvidia-ctk cdi generate
command. This ensures that the executable path for the generated
hooks can be specified consistently.
Since the NVIDIA Container Runtime already allows for the executable
path to be specified in the config the utility code to update the
LDCache and create other nvidia-ctk hooks are also updated.

The HostPath field was added in the v0.5.0 CDI specification.
The cdi package uses strict unmarshalling when loading specs
from file causing failures for unexpected fields.
Since the behaviour for HostPath == "" and HostPath == Path are
equivalent, we clear HostPath if it is equal to Path to ensure
compatibility with the widest range of specs.
This allows, for example, a v0.4.0 spec to be generated as required.

This change extends the support for multiple envvars when
specifying swarm resources to consider ALL of the specified
environment variables instead of the first match.

This change adds the discovery of DRM devices associated with requested
devices. This means that the /dev/dri/card* and /dev/dri/renderD*
devices associated with each requested NVIDIA GPU are injected into
the container and that the /dev/dri/by-path symlinks associated with
these devices are created in the container.

This change adds support for filtering entities by specifying a filter.
This can be used, for example, to check whether a mount or device
has a particular property and removing it from the set of discovered
entities if it does not.

loaders and libraries by modifying the OCI runtime specification.
This allows vulkan applications to run in containers without

If library names are specified, the ldcache is searched otherwise
symlinks are resolved.
