      * Update zlib-src directory to use zlib 1.2.11
        #123245: perl 5.26.1 is vulnerable to CVE-2016-9843, CVE-2016-9841, \ 
CVE-2016-9840, CVE-2016-9842

      * Zlib.xs
        Don't allow offset to be greater than length of buffer in crc32.

      * Zlib.xs
        Change my_zcalloc to use safecalloc.
        The link, https://github.com/madler/zlib/issues/253, is the upstream \ 
report for the remaining
        valgrind errors not already dealt with by 1.2.11. Using calloc in \ 
Zlib.xs for now as a workaround.
