Error reports trace through layers of macroexpansion.

* eval.c (error_trace): New function. Consolidates
error reporting between unhandled exception handling
in uw_throw, and the catcher in the repl.
(op_defmacro, expand_macrolet): Propagate location info from
body to wrapping block, and to the macro binding. In the
latter function, also to the body that is wrapped by local
macros.
(do_expand, macroexpand_1): Propagate location info from macro
expander to expansion, only taking it from the form if the
macro doesn't supply it.

* eval.h (error_trace): Declared.

* parser.c (repl): Replace error reporting code with call to
error_trace.

* unwind.c (uw_throw): uw_throw: likewise.
