dirstate: move opendirstatefile to dirstatemap
As part of moving the dirstate storage logic to another class, let's move
opendirstatefile to dirstatemap. This will allow extensions to replace the
pending abstraction.
Future patches will move the consumers of _opendirstatefile into dirstatemap as
well.

Second scenario with two repos:
$ cd ..
$ hg init r1
$ cd r1
$ mkdir a
$ echo foo > a/f
$ hg add a
adding a/f (glob)
$ hg ci -m "a/f == foo"
$ cd ..
$ hg clone r1 r2
updating to branch default
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd r2
$ hg mv a b
moving a/f to b/f (glob)
$ echo foo1 > b/f
$ hg ci -m" a -> b, b/f == foo1"
$ cd ..
$ cd r1
$ mkdir a/aa
$ echo bar > a/aa/g
$ hg add a/aa
adding a/aa/g (glob)
$ hg ci -m "a/aa/g"
$ hg pull ../r2
