dpdk compress code is almost ready.

https://github.com/Linaro/dpdk/tree/next-11.24-compress.

The dpdk only support deflate,

We added some hack to use zlib, which will be removed when testing deflate

- setup.alg_type = WD_ZLIB;

+ setup.alg_type = WD_DEFLATE;

- udev = wd_get_accel_dev("zlib");

+ udev = wd_get_accel_dev("deflate");

Test:

Prepare hugepage, only one time
