Add function zip:foldl/3 to iterate over zip archives

This is the public interface of prim_zip:open/3,
which has been used in earlier releases by both
erl_prim_loader and escript. The new function
can be used as a replacement for the undocumented
function escript:foldl/3 that is likely to be
removed without further notice.

The error handling of prim_zip:open/3 (and
prim_zip:foldl/3) has been improved in order to
better suite a public interface. For example it
could happen that a file or a zlib port could be
left open in some errors cases.

The documentation of the FileSpec parameter to
zip:create/3 has been updated to show that
file info can be explicitly specified. A FileSpec
may contain {Filename, binary(), #file_info{}}
elements. The function zip:create/3 was already
prepared to partly support this, but now after
a few minor fixes it is fully supported.
