memctx: calculate exact status being committed from specified files

Before this patch, "memctx._status" is initialized by "(files, [], [],
[], [], [], [])" and this causes "memctx.modified" to include not
only modified files but also added and removed ones incorrectly.

This patch adds "_status" method to calculate exact status being
committed according to "files" specified at construction time.

Exact "_status" is useful to share/reuse logic of committablectx.

This patch is also preparation for issues fixed by subsequent patches.

Some details of changes for tests in this patch:

  - some filename lines are omitted in "test-convert-svn-encoding.t",
    because they are correctly listed up as "removed" files

    those lines are written out in "localrepository.commitctx" for
    "modified" and "added" files by "ui.note".

  - "| fixbundle" filterring in "test-histedit-fold.t" is omitted to
    check lines including "added" correctly

    "fixbundle" discards all lines including "added".

  $ hg init repo
  $ cd repo

  $ echo line 1 > foo
  $ hg ci -qAm 'add foo'

copy foo to bar and change both files
  $ hg cp foo bar
  $ echo line 2-1 >> foo
  $ echo line 2-2 >> bar
  $ hg ci -m 'cp foo bar; change both'

in another branch, change foo in a way that doesn't conflict with
the other changes
  $ hg up -qC 0
  $ echo line 0 > foo
  $ hg cat foo >> foo
  $ hg ci -m 'change foo'
  created new head

we get conflicts that shouldn't be there
