For users running the nvidia-container-runtime it would be useful
to determine the runtime mode used from the logs directly instead
of relying on other log messages as signals. This change ensures
that an explicitly selected mode is also logged instead of only
when mode=auto.

This change adds a --relative-to option to the nvidia-ctk transform root
command. This defaults to "host" maintaining the existing behaviour.
If --relative-to=container is specified, the root transform is applied to
container paths in the CDI specification instead of host paths.

This change switches to using the reflect package to determine
the type of config options instead of inferring the type from the
Toml data structure.

This change adds support for an NVIDIA_NVSWITCH environment variable.
When set to `enabled` this striggers the injection of all available
/dev/nvidia-nvswitch* device nodes.

Instead of relying solely on a static config, we resolve the path
to ldconfig. The path is checked for existence and a .real suffix is preferred.

This change skips the update of ld.cache in the container if it
doesn't exist. Instead, the -N flag is used to only create the
relevant symlinks.

This change refactors the use of the symlink filter to make it extendible.
A blocked filter can be set on the Tegra CSV discoverer to ensure that the correct
symlink libraries are filtered out. Here, globs can be used to select mulitple libraries,
and a **/ prefix on the globs indicates that the pattern that follows is only applied to
the filename of the symlink entry in the CSV file.
A --csv.ignore-pattern command line argument is added to the nvidia-ctk cdi generate
command that allows this to be set.

This change adds a "required" option to the new toml config
that controls whether a default config is returned or not.
This is useful from the NVIDIA Container Runtime Hook, where
/run/driver/nvidia/etc/nvidia-container-runtime/config.toml
is checked before the standard path.
This fixes a bug where the default config was always applied
when this config was not used.

This change adds a UsesNVGPUModule function that checks whether the nvgpu
kernel module is used by NVML. This allows for more robust detection of
Tegra-based platforms where libnvidia-ml.so is supported to enumerate the
iGPU.

This change renames the csv.library-search-path option to
library-search-path so as to be more generally applicable in
future. Note that the option is still only applied in csv mode.

This change removes installation of the oci-nvidia-hook files.
These files conflict with CDI use in runtimes that support it.
The use of the hook should be considered deprecated on these platforms.
If a hook is required, the
nvidia-ctk runtime configure --config-mode=oci-hook
command should be used to create the hook file(s).

This change extends the nvidia-ctk runtime configure command
with a --config-mode=oci-hook that creates an OCI hook json file.

The debian and rpm packages are updated to trigger the generation of

This change adds an nvidia-container-runtime-hook.path config option
to allow the path used for the prestart hook to be overridden. This
is useful in cases where multiple NVIDIA Container Toolkit installations
are present.
