sparse: variable to track if sparse is enabled

Currently, the sparse extension sniffs repo instances for
attributes defined by the sparse extension to determine if
sparse is enabled. As we move code away from repo instances,
these checks will be a bit more brittle.

We introduce a module-level variable to track whether sparse is
enabled as a temporary workaround.

  $ hg init

  $ echo 123 > a
  $ hg add a
  $ hg commit -m "first" a

  $ mkdir sub
  $ echo 321 > sub/b
  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
  sub not present
