zip_util_pkg is out of date

[GoogleCodeExporter]

Using the included zip_util_pkg results in errors when trying to ZIP a ZIP file 
(I know it won't get any smaller, but customer needs this for convenience sake).

Version referenced is: 21.05.2012

Version of code referenced here seems to fix the issue:

The as_zip link above is not the latest and greatest.

The following is much more current:
https://technology.amis.nl/wp-content/uploads/2010/06/as_zip8.txt
I've done a comparative analysis of it and what is in alexandria.

To do this I normalized the whitespace of zip_util_pkg.pkb to match the style 
of as_zip8.txt. Also re-ordered the subroutines to match as_zip8.txt.

To do the comparison, I extracted just the package body from as_zip8.txt.

I've heavily commented the results. See -- DMS comments for details.

Best compared in a quality diff/merge program with whitespace, newlines and 
case ignored.

It appears to me that as_zip8 allows for:
stored files (not compressed)
large files (bigger than 4G)
empty files
folders
names having UTF-8 characters
auto-detection of character set encoding
