[PATCH] wc-ng task: Remove svn_wc_entry_t's obtained only to find svn_node_kind_t.

wc-ng gurus:

While trying (fruitlessly) to track down a switch test segfault last
Friday I noticed that in several places we grab an svn_wc_entry_t
simply so we can find a path's svn_node_kind_t. This seems like an
obvious place to get rid of some entry structures, so here's a stab at
doing just that.

The only seeming difficulty/question in this task is deciding how we
map svn_wc__db_kind_t to svn_node_kind_t. The attached patch takes
this approach:

svn_wc__db_kind_dir (not hidden*) --> svn_node_dir
svn_wc__db_kind_dir (hidden*) --> svn_node_none
svn_wc__db_kind_file (not hidden*) --> svn_node_file
svn_wc__db_kind_file (hidden*) --> svn_node_none
svn_wc__db_kind_symlink --> svn_node_unknown
svn_wc__db_kind_unknown --> svn_node_unknown
svn_wc__db_kind_subdir --> svn_node_unknown

* As per svn_wc__db_node_hidden(). This is necessary because
svn_wc__db_check_node() might report that a path is a
svn_wc__db_kind_dir or svn_wc__db_kind_file, when in fact the path has
been deleted. This can happen if the path's parent is at an revision
at which the child path was not deleted.

Does that seem correct?

Debug build of trunk_at_38776 [ra_local] x [fsfs] passes all tests on Windows.


Stop getting svn_wc_entry_t's when all we want to know is the svn_node_kind_t.

* subversion/include/private/svn_wc_private.h
  (svn_wc__node_get_kind): New.

* subversion/libsvn_wc/node.c
  (svn_wc__node_get_kind): New.

* subversion/libsvn_client/export.c
* subversion/libsvn_client/switch.c
* subversion/libsvn_client/update.c
  Remove calls to svn_wc__get_entry_versioned() or svn_wc_entry() when the
  entry obtained is used only to determine svn_node_kind_t, use
  svn_wc__node_get_kind() instead.

* subversion/libsvn_client/merge.c
  (calculate_merge_inheritance): Remove entry parameter, add scratch_pool
  parameter, and get kind with svn_wc__node_get_kind().
  (get_mergeinfo_paths): Remove call to svn_wc__get_entry_versioned() and
  update call to calculate_merge_inheritance().
