zlib sources removed from this tree

This, for whatever reason, breaks std::fs exception handling.

All remaining external projects will be moved to use this approach soon.
This is to prepare it for more new libraries which would otherwise make
the tree grow even further.

-/* zpipe.c: example of proper use of zlib's inflate() and deflate()
-   Not copyrighted -- provided to the public domain
-   Version 1.4  11 December 2005  Mark Adler */
-
-/* Version history:
-   1.0  30 Oct 2004  First version
-   1.1   8 Nov 2004  Add void casting for unused return values
-                     Use switch statement for inflate() return values
-   1.2   9 Nov 2004  Add assertions to document zlib guarantees
-   1.3   6 Apr 2005  Remove incorrect assertion in inf()
-   1.4  11 Dec 2005  Add hack to avoid MSDOS end-of-line conversions
-                     Avoid some compiler warnings for input and output buffers
