In the redis, the gettimeofday uses too much CPU, even using the
vdso. This patch is useful to avoid wasting CPU cycles and
improve the performance.

1.Close #22.
2.Configure the HW indirection table when initializing port.
3.Use several LSBs of the rss hash result according to reta_size when
calculating queue index.
Other arg is mostly configure file. And this
patch will support it. User can use the configure
file specified.

For using the redis, we should allow users to configure
theirs configure file. Now fstack uses the options as below:
—-conf config.ini --proc-type= --proc-id=
And we should skip 4 args(including program name arg), not 3.
Use the redis-config-file:
bin/redis-server --conf config.ini \
--proc-type=primary --proc-id=0 redis-3.2.8/redis.conf

The ring length of some NIC devices(e.g vmxnet3 ) should be
between 512-4096. We should change the TX_QUEUE_SIZE from 256 to 512
and make sure we can use the f-stack in vmxnet3.

Since f-stack run with polling mode, nginx will call gettimeofday every loop, and cost a lot.
With this commit, f-stack will update current timespec periodically in
ff_hardclock_job. And ff_gettimeofday will get this value.
In nginx, hijack gettimeofday to call ff_gettimeofday.
When use nginx as a proxy, nginx error logs always print 'readv() failed
(9: Bad file descriptor) while reading upstream'.
In previous commit: 10c5711ed2, i removed
`readv`, caused this issue.
Since ngx_ff_module.c was derived from nginx_ofp's ngx_ofp_module.c, but
according to #42, nginx_ofp's ngx_ofp_module.c may be derived from
opendp/dpdk-nginx's ans_module.c and nginx_ofp didn't have a license, so
add opendp/dpdk-nginx's license.
The newer version of libcrypto will invoke read and close function when
dl_init, the real address of read/close function can’t be determined in
compilation phase and libcrypto will seek read/close symbol in ELF
files and other libraries. However nginx_fstack redefined these two
functions, this causes these symbols to be found in nginx_fstack. But the real read/close function is NULL before ff_mod_init, this leads to crash.
Changes:
1.if real_close is NULL, assign it with the address of close function in Glibc.
2.remove unnecessary read/readv/write.
