[PATCH] Replace entries in revision

Hi!

I have run the merge_tests on this patch. When grepping I only found
this code to be used there. If this looks ok, I'll run a make check on
it.

[[[
As part of WC-NG, remove some uses of svn_wc_entry_t.

* subversion/libsvn_wc/revision_status.c
  (status_baton): Rename this...
  (walk_baton): .. to this.
  (analyze_status): Change this to implement svn_wc__node_func_t and use
    WC-NG funcs instead of information in svn_wc_entry_t.
  (svn_wc_revision_status2): Use svn_wc__node_walk_children() instead of
    svn_wc_walk_status() to spare us from the overhead of invoking an
    editor.
]]]

The entries code transformed svn_depth_unknown to svn_depth_infinity. I
check for them both when determing if we have a sparse checkout.

Bert told me that in WC-NG we check for svn_depth_exclude with the
status. Did so, hope it's right.

Bert told me that svnversion (the primary user of the revision_status
functionality as I understood it) didn't take absent or excluded items
into account so I set the show_hidden parameter of
svn_wc__node_walk_children to FALSE.

I could have moved the check for the url out of analyze_status() but I
just wanted to remove some entries and get out of there as fast as I
could. I'm still afraid of libsvn_wc!
