Merge branch 'jk/upload-pack-hook'

"upload-pack" allows a custom "git pack-objects" replacement when
responding to "fetch/clone" via the uploadpack.packObjectsHook.

* jk/upload-pack-hook:
  upload-pack: provide a hook for running pack-objects
  t1308: do not get fooled by symbolic links to the source tree
  config: add a notion of "scope"
  config: return configset value for current_config_ functions
  config: set up config_source for command-line config
  git_config_parse_parameter: refactor cleanup code
  git_config_with_options: drop "found" counting
