A previous change allowed Git to parse bundles with the 'filter' capability. Now, teach Git to create bundles with this option. Some rearranging of code is required to get the option parsing in the correct spot. There are now two reasons why we might need capabilities (a new hash algorithm or an object filter) so that is pulled out into a place where we can check both at the same time. The --filter option is parsed as part of setup_revisions(), but it expected the --objects flag, too. That flag is somewhat implied by 'git bundle' because it creates a pack-file walking objects, but there is also a walk that walks the revision range expecting only commits. Make this parsing work by setting 'revs.tree_objects' and 'revs.blob_objects' before the call to setup_revisions().
