Stop using svn_error__locate in the public ABI. We can't delete it from the ABI, but we can at least do this much.
* subversion/include/svn_error.h (svn_error__locate): Move this prototype, and the four macros that call it, into an #ifdef SVN_DEBUG section. No public API change. * subversion/libsvn_subr/error.c (error_file, error_line): Move to an #ifdef SVN_DEBUG section. (svn_error__locate): Do nothing unless SVN_DEBUG. (make_error_internal): Only set ->file and ->line if SVN_DEBUG. As svn_types.h says, these are "Only used iff @c SVN_DEBUG."
