/* Fill in *STATUS for PATH, whose entry data is in ENTRY.  Allocate
   *STATUS in POOL.

   ENTRY may be null, for non-versioned entities.  In this case, we
   will assemble a special status structure item which implies a
   non-versioned thing.

   PARENT_ENTRY is the entry for the parent directory of PATH, it may be
   NULL if ENTRY is NULL or if PATH is a working copy root.  The lifetime
   of PARENT_ENTRY's pool is not important.

   PATH_KIND is the node kind of PATH as determined by the caller.
   NOTE: this may be svn_node_unknown if the caller has made no such
   determination.

   If PATH_KIND is not svn_node_unknown, PATH_SPECIAL indicates whether
   the entry is a special file.

   If GET_ALL is zero, and ENTRY is not locally modified, then *STATUS
   will be set to NULL.  If GET_ALL is non-zero, then *STATUS will be
   allocated and returned no matter what.

   If IS_IGNORED is non-zero and this is a non-versioned entity, set
   the text_status to svn_wc_status_none.  Otherwise set the
   text_status to svn_wc_status_unversioned.

   If non-NULL, look up a repository lock in REPOS_LOCKS and set the repos_lock
   field of the status struct to that lock if it exists.  If REPOS_LOCKS is
   non-NULL, REPOS_ROOT must contain the repository root URL of the entry.

   yet exist, and the REPOS_TEXT_STATUS indicates that this is an
   addition, create a new status struct using the hash's pool.

   If IS_DIR_BATON is true, THIS_DIR_BATON is a *dir_baton cotaining the out
   of date (ood) information we want to set in BATON.  This is necessary
   because this function tweaks the status of out-of-date directories
   (BATON == THIS_DIR_BATON) and out-of-date directories' parents
   (BATON == THIS_DIR_BATON->parent_baton).  In the latter case THIS_DIR_BATON
   contains the ood info we want to bubble up to ancestor directories so these
   accurately reflect the fact they have an ood descendant.

   Merge REPOS_TEXT_STATUS and REPOS_PROP_STATUS into the status structure's
   "network" fields.

   Iff IS_DIR_BATON is true, DELETED_REV is used as follows, otherwise it
   is ignored:

       optionally the revision path was deleted, in all other cases it must
       be set to SVN_INVALID_REVNUM.  If DELETED_REV is not
       SVN_INVALID_REVNUM and REPOS_TEXT_STATUS is svn_wc_status_deleted,
       then use DELETED_REV to set PATH's ood_last_cmt_rev field in BATON.
       If DELETED_REV is SVN_INVALID_REVNUM and REPOS_TEXT_STATUS is
       svn_wc_status_deleted, set PATH's ood_last_cmt_rev to its parent's
       ood_last_cmt_rev value - see comment below.
