REVISION SUMMARY
  Adjustments:
  
  - renamed src to hgext/narrow
  - marked extension experimental
  - added correct copyright header where it was missing
  - updated hgrc extension enable line in library.sh
  - renamed library.sh to narrow-library.sh
  - dropped all files from repo root as they're not interesting
  - dropped test-pyflakes.t, test-check-code.t and test-check-py3-compat.t
  - renamed remaining tests to all be test-narrow-* when they didn't already
  - fixed test-narrow-expanddirstate.t to refer to narrow and not narrowhg
  - fixed tests that wanted `update -C .` instead of `merge --abort`
  - corrected a two-space indent in narrowspec.py
  - added a missing _() in narrowcommands.py
  - fixed imports to pass the import checker
  - narrow only adds its --include and --exclude to clone if sparse isn't enabled to avoid breaking test-duplicateoptions.py. This is a kludge, and we'll need to come up with a better solution in the future.
  
  These were more or less the minimum to import something that would
  pass tests and not create a bunch of files we'll never use.
  
  Changes I intend to make as followups:
  
  - rework the test-narrow-*-tree.t tests to use the new testcases functionality in run-tests.py
  - remove lots of monkeypatches of core things
