windows: use normalized path as path to subrepo

path to subrepo is used to identify or check location of subrepo.

it should be normalized (in "/" delimiter form), because it is also
used with narrowmatcher which uses only normalized path even on
Windows environment.

this patch applies "util.pconvert()" on path to subrepo (called
"subpath") to normalize it.

for this patch, referers of below were checked.

  - subrepo.state()
  - subrepo.itersubrepos()
  - subrepo.subrepo()
  - context.sub()
  - context.substate()

typical usecase is:

    for subpath in ctx.substate:
        sub = ctx.sub(subpath)
        ... ctx.substate[subpath] ....

in this case, normalization has no side effect, because keys given
from substate are used as key itself.

other cases shown below also seem to require subpath to be normalized.

    - path components are joined by "/", in "commands.forget()":

        for subpath in ctx.substate:
            subforget[subpath + '/' + fsub] = (fsub, sub)

    - normalized "file" is used to check below condition, in
      "commands.revert()", "localrepository.commit()", and
      "localrepository._checknested()"

        file in ctx.substate

    - substate.keys() is passed to dirstate.walk()/status() which use
      only normalized pathes

Source bundle was generated with the following script:

# hg init
# echo a > a
# ln -s a l
# hg ci -Ama -d'0 0'
# mkdir b
# echo a > b/a
# chmod +x b/a
# hg ci -Amb -d'1 0'

  $ hg init
  $ hg -q pull "$TESTDIR/bundles/test-manifest.hg"

The next call is expected to return nothing:

  $ hg manifest

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

  $ hg manifest
  a
  b/a
  l

  $ hg manifest -v
  644   a
  755 * b/a
  644 @ l

  $ hg manifest --debug
  b789fdd96dc2f3bd229c1dd8eedf0fc60e2b68e3 644   a
  b789fdd96dc2f3bd229c1dd8eedf0fc60e2b68e3 755 * b/a
  047b75c6d7a3ef6a2243bd0e99f94f6ea6683597 644 @ l

  $ hg manifest -r 0
  a
  l

  $ hg manifest -r 1
  a
  b/a
  l

  $ hg manifest -r tip
  a
  b/a
  l

  $ hg manifest tip
  a
  b/a
  l

  $ hg manifest --all
  a
  b/a
  l

The next two calls are expected to abort:

  $ hg manifest -r 2
  abort: unknown revision '2'!
  [255]

  $ hg manifest -r tip tip
  abort: please specify just one revision
  [255]
