snapshot: extract parent chain computation
The final step of this series is to include chain related to "prev" in the
search. Before adding that code we do some simple code movement to clarify the
next diff.

Rebase a simple DAG:

$ hg debugdrawdag <<'EOS'

$ hg up -C a

Add a symlink and executable file:
$ hg up -C c

$ ln -s somefile e
$ echo f > f
$ chmod +x f
$ hg add e f
$ hg amend -q
$ hg up -Cq a
Write files to the working copy, and ensure they're still there after the rebase
$ echo "abc" > a
$ ln -s def b
$ echo "ghi" > c
$ echo "jkl" > d
$ echo "mno" > e
