Migrate the in_range(symbol, section) and symbol_iter(module, section) utility functions

from lldbutil.py to the lldb.py proper.  The in_range() function becomes a function in
the lldb module.  And the symbol_iter() function becomes a method within the SBModule
called symbol_in_section_iter().  Example:

        # Iterates the text section and prints each symbols within each sub-section.
        for subsec in text_sec:
            print INDENT + repr(subsec)
            for sym in exe_module.symbol_in_section_iter(subsec):
                print INDENT2 + repr(sym)
                print INDENT2 + 'symbol type: %s' % symbol_type_to_str(sym.GetType())

might produce this following output:
