4ed3418a43 Unbreak Viewperf by reverting "util: use crc32_z instead of crc32 and bump zlib dep to 1.2.9" 
It breaks apps shipping their own copy of zlib, such as Viewperf.
If we use crc32_z, Viewperf is unable to start because it's an undefined
symbol.

This reverts commit 010272b62e.

010272b62e util: use crc32_z instead of crc32 and bump zlib dep to 1.2.9 
1.2.9 has been released in January 2017, so let's assume
we'll find it everywhere.

6acf22a179 util: use faster zlib's CRC32 implementaion 
zlib provides a faster slice-by-4 CRC32 implementation than the
traditional single byte lookup one used by mesa. As most supported
platforms now link zlib unconditionally, we can easily use it.

Improvement for a 1MB buffer (avg MB/s, n=100, zlib 1.2.8):

  i5-6600K                    C2D E4500
mesa zlib                    mesa zlib
 443 1443 225% +/- 2.1%       403 1175 191% +/- 0.9%

It has been verified the calculation results stay the same after this
change.
