Enable atomic swap and store macro with acquire and release ordering

Add atomic swap and store macro with acquire and release ordering
respectively. Variable in question is interupt_pending variable which
is used as guard variable by input nodes to process the device queue.

Atomic Swap is used with Acquire ordering as writes or reads following
this in program order should not be reordered before the swap.

Atomic Store is used with Release ordering, as post store the node is
added to pending list.

# 26054ea1 20-Jun-2017 Christophe Fontaine <christophe.fontaine@enea.com>

Fix SIGBUS on aarch64

A call to 'clib_smp_swap (&((dq)->interrupt_pending), 0)' was creating
a SIGBUS.
Instead of making dq->interrupt_pending aligned on 64bits, we reduce the size
from uword (u64) to u32, as the number of pending interrupts will never
go above max of u32.

# 586afd76 05-Apr-2017 Damjan Marion <damarion@cisco.com>

Use thread local storage for thread index

This patch deprecates stack-based thread identification,
Also removes requirement that thread stacks are adjacent.

Finally, possibly annoying for some folks, it renames
all occurences of cpu_index and cpu_number with thread
index. Using word "cpu" is misleading here as thread can
be migrated ti different CPU, and also it is not related
to linux cpu index.

# eb743fad 20-Mar-2017 Damjan Marion <damarion@cisco.com>

vnet: add device-input threadplacement infra

This change adds two new debug CLI command:

- "show interface placmenet" to display which
thread (main or worker) is responsible for processing
interface rx queue

vpp# show interface placement
Thread 0 (vpp_main):
node af-packet-input:
host-vpp1 queue 0
Thread 1 (vpp_wk_0):
node af-packet-input:
host-virbr0 queue 0
Thread 2 (vpp_wk_1):
node af-packet-input:
host-vpp2 queue 0
host-lxcbr0 queue 0

- "set interface placmenet" to assign thread (main or worker)
which process specific interface rx queue

vpp# set interface placement host-vpp1 queue 0 main
