This change allows the NVIDIA Container Runtime to inject vulkan
loaders and libraries by modifying the OCI runtime specification.
This allows vulkan applications to run in containers without
additional modifications.

This change adds a Locator that can be used to locate libraries.
If library names are specified, the ldcache is searched otherwise
symlinks are resolved.

This change adds a modifier to that injects the tegra platform files
* /etc/nv_tegra_release
* /sys/devices/soc0/family
allowing these files to be used for platform detection in a containerized
context such as the GPU device plugin.

This change adds a root member to the mounts type that is used to
perform most of the lookups for files and devices. This allows
for consistent handling of relative paths.
Signed-off-by: Evan Lezar <elezar@nvidia.com>
The Relative method added to the Locator interface was
not correctly implemented in the file type. The root was
never set when instantiating the object.
This change removes this method from the interface and the file
type, switching to a local implementation in the mounts type
instead.

Since the creation of symlinks may include other libraries / folders
the ldcache should be updated AFTER the symlinks are created.

In preparation for adding a command to the nvidia-ctk CLI to modify
the docker config, this change refactors load, update, and flush logic
from the toolkit container docker CLI to an internal package.

This change adds an nvidia-container-runtime.modes.cdi.spec-dirs
config option that allows the default spec dirs to be overridden.

This change reuse the code that checks for the existing NVIDIA
Container Runtime hook to ensure that both nvidia-container-toolkit
and nvidia-container-runtime-hook are detected.

This mirrors what is done in cri-o and allows for devices nodes
from, for example, the driver container to be injected into a
container at /dev instead of <ROOT>/dev

This change adds a charDevices discoverer and using this
for CSV, GDS, and MOFED discovery. Internally the discoverer
is a "mounts" discoverer with a charDevice locator.
Signed-off-by: Evan Lezar <elezar@nvidia.com>
Instead of creating a set of discoverers per file, this change creates
a discoverer per type by first concatenating the mount specifications
from all files. This will allow all device nodes, for example, to
be treated as a single device.

This adds a Relative function to the Locator interface and uses
this to determine the host and container paths for located files
(and devices). This ensures that the root (e.g. the nvidia driver
root) is stripped from the container path.

This change creates GDS and MOFED modifiers and adds them to the
modifer created for the selected runtime mode if the NVIDIA_GDS
and NVIDIA_MOFED envvars are set to "enabled", respectively.

This change adds version output to the nvidia-continer-runtime,
nvidia-container-toolkit, and nvidia-ctk CLIs. The same version
is used in all cases and includes a version string and a git
revision if set.
The construction of the version string mirrors what is done in runc.

These changes replace the nvidia-container-runtime config options
experimental and discover-mode with a single mode config option.
Note that mode is now a string with a default value of "auto"
and a mode value of "legacy" is equivalent to experimental == false.
