doc: simplify Linux paramter rcu_nocbs in PVP benchmark

From Documentation/admin-guide/kernel-parameters.txt, specifically the
last sentence:

nohz_full= [KNL,BOOT,SMP,ISOL]
The argument is a cpu list, as described above.
In kernels built with CONFIG_NO_HZ_FULL=y, set
the specified list of CPUs whose tick will be stopped
whenever possible. The boot CPU will be forced outside
the range to maintain the timekeeping. Any CPUs
in this list will have their RCU callbacks offloaded,
just as if they had also been called out in the
rcu_nocbs= boot parameter.

The kernel or-s the nohz_full cpumask into the rcu_nocbs cpumask at
startup, and uses that.

mk: use linux and freebsd in config names

Rather than using linuxapp and bsdapp everywhere, we can change things to
use the, more readable, terms "linux" and "freebsd" in our build configs.
Rather than renaming the configs we can just duplicate the existing ones
with the new names using symlinks, and use the new names exclusively
internally. ["make showconfigs" also only shows the new names to keep the
list short] The result is that backward compatibility is kept fully but any
new builds or development can be done using the newer names, i.e. both
"make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc"
work.

app/testpmd: disable Rx VLAN offloads by default

Removed the hardcoded preconfigured Rx VLAN offload configuration
from testpmd and changed the Rx offload command line parameters from
disable to enable.

It has been decided by the Technical Board that testers who wish to
use these offloads will now have to explicitly write them in the
command-line when running testpmd.
The agreement is to keep two exceptions enabled by default in 18.02:
Rx CRC strip and Tx fast free.

Motivation:
Some PMDs such at the mlx4 may not implement all the offloads.
After the offload API rework assuming no offload is enabled by default,
commit ce17eddefc20 ("ethdev: introduce Rx queue offloads API")
commit cba7f53b717d ("ethdev: introduce Tx queue offloads API") trying
to enable a not supported offload is clearly an error which will cause
configuration failing.

Considering that testpmd is an application to test the PMD, it should
not fail on a configuration which was not explicitly requested.
The behavior of this test application is then turned to an opt-in
model.

Not relying on external vSwitch ease integration in a CI loop by
not being impacted by DPDK API changes.
