[PATCH] wc-ng - Remove use of entry_t from calculate_target_mergeinfo

Trying to remove more uses of svn_wc_entry_t, it seems there is no way
at the moment to get the equivalent of entry->copied using node
routines. Is this the sort of thing that is needed?

[[[
wc-ng: work towards eliminating svn_wc_entry_t

* libsvn_wc/node.c, include/private/svn_wc_private.h
     Add svn_wc__node_is_status_copied()

* subversion/libsvn_client/copy.c
     (calculate_target_mergeinfo): Remove unused 'no_repos_access'
       parameter, replace use of svn_wc__get_entry with node routines.
