The v3 bundle format has capabilities, allowing newer versions of Git to create bundles with newer features. Older versions that do not understand these new capabilities will fail with a helpful warning. Create a new capability allowing Git to understand that the contained pack-file is filtered according to some object filter. Typically, this filter will be "blob:none" for a blobless partial clone. This change teaches Git to parse this capability, place its value in the bundle header, and demonstrate this understanding by adding a message to 'git bundle verify'. Since we will use gently_parse_list_objects_filter() outside of list-objects-filter-options.c, make it an external method and move its API documentation to before its declaration.
