dirstate: make functions for backup aware of transaction activity

Some comments in this patch assume that subsequent patch changes
'dirstate.write()' like as below:

    def write(self, repo):
        if not self._dirty:
            return
        tr = repo.currenttransaction()
        if tr:
            tr.addfilegenerator('dirstate', (self._filename,),
                                self._writedirstate, location='plain')
            return # omit actual writing out
        st = self._opener('dirstate', "w", atomictemp=True)
        self._writedirstate(st)

This patch makes '_savebackup()' write in-memory changes out, and it
causes clearing 'self._dirty'. If dirstate isn't changed after
'_savebackup()', subsequent 'dirstate.write()' never invokes
'tr.addfilegenerator()' because 'not self._dirty' is true.

Then, 'tr.writepending()' unintentionally returns False, if there is
no other (e.g. changelog) changes pending, even though dirstate
changes are already written out at '_savebackup()'.

To avoid such situation, this patch makes '_savebackup()' explicitly
invoke 'tr.addfilegenerator()', if transaction is running.

'_savebackup()' should get awareness of transaction before 'write()',
because the former depends on the behavior of the latter before this
patch.

PatchReview Introduction                                  *patchreview-intro*

The Patch Review plugin allows easy single or multipatch code or diff reviews.

It opens each affected file in the patch or in a workspace diff in a diff view
in a separate tab.

VIM provides the |:diffpatch| and related commands to do single file reviews
but can not handle patch files containing multiple patches as is common with
software development projects. This plugin provides that missing
functionality.

It also improves on |:diffpatch|'s behavior of creating the patched files in
the same directory as original file which can lead to project workspace
pollution.

It does automatic diff generation for various version control systems by
running their diff command.

PatchReview Options                                     *patchreview-options*

  g:patchreview_patch = {string}
      Optional path to patch binary. PatchReview tries to locate patch on
      system path automatically. If the binary is not on system path, this
      option tell PatchReview the full path to the binary.  This option, if
      specified, overrides the default patch binary on the path.

    examples:
        (On Windows with Cygwin) >
           let g:patchreview_patch = 'c:\\cygwin\\bin\\patch.exe'
<
        (On *nix systems) >
           let g:patchreview_patch = '/usr/bin/gpatch'
<

  g:patchreview_filterdiff = {string}
      Optional path to filterdiff binary. PatchReview tries to locate
      filterdiff on system path automatically. If the binary is not on system
      path, this option tell PatchReview the full path to the binary.  This
      option, if specified, overrides the default filterdiff binary on the
      path.

     examples:
        (On Windows with Cygwin)
>
           let g:patchreview_filterdiff = 'c:\\cygwin\\bin\\filterdiff.exe'
<
        (On *nix systems)
>
           let g:patchreview_filterdiff = '/usr/bin/filterdiff'

PatchReview Usage                                          *patchreview-usage*
                                                                *:DiffReview*

  :DiffReview

    Perform a diff review in the current directory under version control.
    Currently supports Mercurial (hg), Subversion (svn), CVS, Bazaar (bzr) and
    Monotone.

                                                                *:PatchReview*

  :PatchReview patchfile_path [optional_source_directory]

    Perform a patch review in the current directory based on the supplied
    patchfile_path. If optional_source_directory is specified, patchreview is
    done on that directory. Otherwise, the current directory is assumed to be
    the source directory.

    Only supports context or unified format patches.
