8To Update:
9  1) Unpack vendor sources into a clean directory.
10  2) Import onto the vendor area.
11  3) Merge the vendor tree to sys/contrib/zlib, which contains a stripped down
12     version of upstream source, resolve any conflicts.
13  4) Double check zconf.h, zlib.pc, and Symbol.map to make sure that we
14     have the required changes.  Test universe and commit them.
