Jeremy Hylton 280c81a940 Need to support single_input explicitly so from __future__ imports
are legal at the interactive interpreter prompt.  They don't do
anything yet...

Jeremy Hylton 39e2f3f824 Presumed correct compiler pass for future statements
XXX still need to integrate into symtable API

compile.h: Remove ff_n_simple_stmt; obsolete.

           Add ff_found_docstring used internally to skip one and only
           one string at the beginning of a module.

compile.c: Add check for from __future__ imports to far into the file.

 	   In symtable_global() check for -1 returned from
	   symtable_lookup(), which signifies name not defined.

	   Add missing DECERF in symtable_add_def.

           Free c->c_future.

future.c:  Add special handling for multiple statements joined on a
	   single line using one or more semicolons; this form can
           include an illegal future statement that would otherwise be
           hard to detect.

	   Add support for detecting and skipping doc strings.
