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.

This change switches to generating a OCI runtime hook to create
individual symlinks instead of processing a CSV file in the hook.
This allows for better reuse of the logic generating CDI
specifications, for example.

This change adds a symlinks.Resolve function for resolving symlinks and
updates usages across the code to make use of it.

This chagne allows the csv mode option to specified in the
nvidia-ctk cdi generate command and adds a --csv.file option
that can be repeated to specify the CSV files to be processed.

This change ensures that libcuda.so can be located on systems
where no patch version is specified in the driver version.

These changes remove the use of discover.Config which was used
to pass the driver root and the nvidiaCTK path in some cases.
Instead, the nvidiaCTKPath is resolved at the begining of runtime
invocation to ensure that this is valid at all points where it is
used.

This change adds a GetDefaultConfigToml function to the config package.
This function returns the default config in the form of raw TOML
including comments. This is useful for generating a default config at
installation time, with platform-specific differences codified.

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.
