This change adds a GetContainerRoot to the oci.State type to
encapsulate the logic around determining the container root.
This Fixes a bug where relative roots (e.g. as generated by contianerd)
are not supported.

This change adds a Requirements abstraction that can be used to check
an images' NVIDIA_REQUIRE_* envvars against the host properties such
as CUDA version or architecture.

This change adds a CUDA image abstraction that encapsulates
the queries performed on a container image (e.g. envvars) to
check certain CUDA properties.

This change adds a DefaultExecutableDir = /usr/bin constant that is used
to construct default paths for executables instead of specifying these
explicitly.

This change adds a cache to the mounts type. This means that if called to get
a list of folders, for example, the result is reused instead of recalculated.
This also avoids duplicate logging.

This change adds a discovered hook for updating the ldcache as a container-create
hook. The mounts from a discoverer are inspected to determine the folders that must
be added to the cache using the nvidia-ctk hook update-ldcache command.
This is added to the "csv" discovery mode for the experimental runtime.

This change adds an 'auto' discover mode that attempts to select the correct mode
for a given platform. This currently attempts to detect whether the platform is a
Tegra-based system in which case the 'csv' discover mode is used. The 'legacy'
discover mode is used as the fallback.

This change ensures that by default, the CSV discovery only considers the base CSV
files (l4t.csv, drivers.csv, devices.csv) and skips the rest unless the
NVIDIA_REQUIRE_JETPACK is set to "csv-mounts=all", in which case, all CSV files in the
specified folder are considered.

This change adds support for a "csv" discovery mode to the experimental runtime.
If this is set with experimental = true, a CSV-based discovery of devices and
mounts are used to define the modifications required to the OCI spec. The edits
are expressed as CDI ContainerEdits.

This change adds a symlink locator that follows symlinks and returns all
elements in the chain and a device locator that finds character devices.
