narrow: import experimental extension from narrowhg revision cb51d673e9c5
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
