bugfix: read print consistency of shadowed symbols.

Suppose that a program-defined package is current, has usr as
its :fallback, and has a :local symbol list. Then if 'usr:list
is printed, it must print with the usr: package symbol because
it is not visible. It is printing without the prefix.

* lib.c (symbol_present): Function renamed to symbol_visible,
which is much more descriptive of what its return value means.
The bug in this function is that it does not stop searching
when, in its search path, it encounters a symbol which has the
same name as sym, but which isn't sym. But such a symbol makes
sym invisible. This is now fixed.
