This change aligns the creation of symlinks under CDI with
the implementation in libnvidia-container. If the driver libraries
are present, the following symlinks are created:
* {{ .LibRoot }}/libcuda.so -> libcuda.so.1
* {{ .LibRoot }}/libnvidia-opticalflow.so -> libnvidia-opticalflow.so.1
* {{ .LibRoot }}/libGLX_indirect.so.0 -> libGLX_nvidia.so.{{ .Version }}

This change converts the toolkit installation logic to a go package
and invokes this installation over the go API instead of starting
this executable.

This change refactors the toml config file handlig for runtimes
such as containerd or crio. A toml.Loader is introduced that
encapsulates loading the required file.
This can be extended to allow other mechanisms for loading
loading the current config.

Since we expect .so.1 symlinks to be created by ldconfig, we don't
explicitly request these. This change removes the creation of
a libnvidia-allocator.so.1 -> libnvidia-allocator.so.RM_VERSION symlink
through the create-symlinks hook.

This change adds the vdpau subfolder to the paths searched
for driver libraries. This allows the libvdpau_nvidia.so.RM_VERSION
library to also be discovered.

This change adds a safe pointer conversion to fix an
incompatible C pointer conversion, which caused build failures on some
architectures.

This change adds a new discoverer for Sandboxutils to report the file
system paths and associated symbolic links using GetGpuResource and
GetFileContent APIs. Both GPU and MIG devices are supported. If the
Sandboxutils discoverer fails, the NVML discoverer is used to report
the file system information.

This change includes the usage of Sandboxutils GetDriverVersion API to
retrieve the CUDA driver version. If the library is not available on the
system or the API call fails for some other reason, it will fallback to
the NVML API to return the driver version.

This change adds manual wrappers around the generated bindings to make
them into more user-friendly APIs for the caller. Some helper functions
are also added.
The APIs that are currently present in the library and implemented here
are:
nvSandboxUtilsInit
nvSandboxUtilsShutdown
nvSandboxUtilsGetDriverVersion
nvSandboxUtilsGetGpuResource
nvSandboxUtilsGetFileContent

This change adds the internal bindings for Sandboxutils, some of which
have been automatically generated with the help of c-for-go. The format
followed is similar to what is used in go-nvml. These would need to be
regenerated when the header file is modified and new APIs are added.

This change adds a script and related files to generate the internal
bindings for Sandboxutils library with the help of c-for-go.
This can be used to update the bindings when the header file is modified
with reference to how they are generated with the Makefile in go-nvml.

With the move to dependabot to udpate the libnvidia-container
submodule it is no longer required to have checks in place that
ensure that this is up to date when building.
In addition when re-building old commits in CI, for example we explicitly
do NOT want to have this check.

This change enables opt-in (off-by-default) features to be opted into.
These features can be toggled by name by specifying the (repeated)
--opt-in-feature command line argument or as a comma-separated list
in the NVIDIA_CONTAINER_TOOLKIT_OPT_IN_FEATURES environment variable.
