This change refactors the use of the symlink filter to make it extendible. A blocked filter can be set on the Tegra CSV discoverer to ensure that the correct symlink libraries are filtered out. Here, globs can be used to select mulitple libraries, and a **/ prefix on the globs indicates that the pattern that follows is only applied to the filename of the symlink entry in the CSV file. A --csv.ignore-pattern command line argument is added to the nvidia-ctk cdi generate command that allows this to be set. Signed-off-by: Evan Lezar <elezar@nvidia.com>
