lfs: add the '{lfsattrs}' template keyword to '{lfs_files}'

This provides access to the metadata dictionary contained within the tracked
pointer file.  The OID is probably the most important attribute, and has its own
keyword.  But we might as well have this for completeness.

I liked {pointer} better, but couldn't make it work with the singular/plural
forms.

#require test-repo

  $ . "$TESTDIR/helpers-testrepo.sh"
  $ cd "`dirname "$TESTDIR"`"

look for python scripts that do not use /usr/bin/env

  $ testrepohg files 'set:grep(r"^#!.*?python") and not grep(r"^#!/usr/bi{1}n/env python") - **/*.t'

In tests, enforce $PYTHON and *not* /usr/bin/env python or similar:
  $ testrepohg files 'set:grep(r"#!.*?python") and **/*.t' \
  > -X tests/test-check-execute.t \
  > -X tests/test-check-module-imports.t \
  > -X tests/test-check-pyflakes.t \
  > -X tests/test-check-shbang.t
  [1]

The above exclusions are because they're looking for files that
contain Python but don't end in .py - please avoid adding more.

look for shell scripts that do not use /bin/sh

  $ testrepohg files 'set:grep(r"^#!.*/bi{1}n/sh") and not grep(r"^#!/bi{1}n/sh")'
