hg: show the correct message when cloning an LFS repo with extension disabled

The `extensions._disabledpaths()` doesn't handle fetching help from `__index__`,
so it returns an empty dictionary of paths.  That means None is always returned
from `extensions.disabled_help()` when embedding resources inside the pyoxidizer
or py2exe binary, regardless of the arg or if is an external extension stored in
the filesystem.  And that means wrongly telling the user with an explicitly
disabled LFS extension that it will be enabled locally upon cloning from an LFS
remote.  That causes test-lfs-serve.t:295 to fail.

This effectively reverts most of the rest of 843418dc0b1b, while keeping the
help text change in place (which was specifically identified as a problem).

Issue1790: dirstate entry locked into unset if file mtime is set into
the future

Prepare test repo:

  $ hg init u
  $ cd u
  $ echo a > a
  $ hg add
  adding a
  $ hg ci -m1

Set mtime of a into the future:

  $ touch -t 203101011200 a

Status must not set a's entry to unset (issue1790):

  $ hg status
  $ hg debugstate
  n 644          2 2031-01-01 12:00:00 a

Test modulo storage/comparison of absurd dates:

#if no-aix
  $ touch -t 195001011200 a
  $ hg st
  $ hg debugstate
  n 644          2 2018-01-19 15:14:08 a

Transaction compatibility
-------------------------

The transaction preserves the dirstate.
We should make sure all of it (docket + data) is preserved

#if dirstate-v2
  $ hg commit -m 'bli'
#endif

  $ hg update --quiet
  $ hg revert --all --quiet
  $ rm -f a
  $ echo foo > foo
  $ hg add foo
  $ hg commit -m foo

#if dirstate-v2
  $ uid=$(find_dirstate_uuid)
  $ touch bar
  $ while [ uid = $(find_dirstate_uuid) ]; do
  >    hg add bar;
  >    hg remove bar;
  > done;
  $ rm bar
#endif
  $ hg rollback
  repository tip rolled back to revision 1 (undo commit)
  working directory now based on revision 1

Check dirstate ordering
(e.g. `src/dirstate/` and `src/dirstate.rs` shouldn't cause issues)

  $ hg init repro
  $ cd repro
  $ mkdir src
  $ mkdir src/dirstate
  $ touch src/dirstate/file1 src/dirstate/file2 src/dirstate.rs
  $ touch file1 file2
  $ hg commit -Aqm1
