On the remote-only-status branch: Simplify the implementation a bit more.

* subversion/libsvn_wc/wc_db.c
  (read_info): Removed parameter base_tree_only. Updated all callers.
  (read_single_info): In the remote-only case, call
   svn_wc__db_base_get_info_internal() and interpret the results to
   construct the info for the base node.

* subversion/libsvn_wc/wc-queries.sql
  (STMT_SELECT_BASE_NODE_INFO, STMT_SELECT_BASE_NODE_INFO_WITH_LOCK):
   Removed two unused statements.
