dirstate: swap pathto() and get_entry() in idirstate

This way the order of methods in dirstate and idirstate classes is the same.
Just to make it easier to use diff tools to compare the two classes.

Define helpers.

  $ hg_log () { hg log -G -T "{rev}:{node|short}"; }
  $ commit () { echo "foo - ${2:-$1}" > $1; hg commit -Aqm "Edited $1"; }
  $ strip() { hg --config extensions.strip= strip -q -r "$1" ; }

Setup hg repo.

  $ hg init repo
  $ cd repo
  $ touch x; hg add x; hg commit -m "initial"
  $ hg clone -q . ../clone
  $ commit a

  $ cd ../clone

  $ commit b

  $ hg pull -q ../repo

  $ cat .hg/cache/branch2-visible

  $ strip '1:'

The branchmap cache is not adjusted on strip.
Now mentions a changelog entry that has been stripped.

  $ cat .hg/cache/branch2-visible

  $ commit c

Not adjusted on commit, either.

  $ cat .hg/cache/branch2-visible

On pull we end up with the same tip, and so wrongly reuse the invalid cache and crash.

  $ hg pull ../repo 2>&1 | grep 'ValueError:'
  ValueError: node a3498d6e39376d2456425dd8c692367bdbf00fa2 does not exist (known-bad-output !)
