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 }}

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 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 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.

This change ensures that the internal CDI representation includes
the persistenced socket if the include-persistenced-socket feature
flag is enabled.

This changes skips the injection of the nvidia-persistenced socket by
default.
An include-persistenced-socket feature flag is added to allow the
injection of this socket to be explicitly requested.

This change moves most of the logging for the NVIDIA Container runtime
from Info to Debug or Trace -- especially in the case where no
modifications are requried.
This removes execessive logging.

This change creates an nvidia-cdi-hook binary for implementing
CDI hooks. This allows for these hooks to be separated from the
nvidia-ctk command which may, for example, require libnvidia-ml
to support other functionality.
The nvidia-ctk hook subcommand is maintained as an alias for the
time being to allow for existing CDI specifications referring to
this path to work as expected.

When running nvidia-ctk on a system that uses a custom XDG_DATA_DIRS
environment variable value, the configuration files for `glvnd`,
`vulkan`, and `egl` fail to get passed through from the host to the
container. Reading from XDG_DATA_DIRS instead of hardcoding the default
value allows for finding said files so they can be mounted in the
container.

This change adds a features config that allows
individual features to be toggled at a global level. Each feature can (by default)
be controlled by an environment variable.
The GDS, MOFED, NVSWITCH, and GDRCOPY features are examples of such features.
