buffer chain linearization

Rewrite vlib_buffer_chain_linearize function so that it works as intended.
Linearize buffer chains coming out of reassembly to work around some
dpdk-tx issues. Note that this is not a complete workaround
as a sufficiently large packet will still cause the resulting chain to
be too long.

Drop features from reassembly code which relies on knowing which and how
many buffers were freed during linearization, buffer counts and tracing
capabilities for these cases.

vhost: VPP stalls with vhost performing control plane actions [VPP-1572]

Symptom
-------
With NDR traffic blasting at VPP, bringing up a new VM with vhost
connection to VPP causes packet drops. I am able to recreate this
problem easily using a simple setup like this.

TREX-------------- switch ---- VPP
    |---------------|  |-------|

Cause
-----
The reason for the packet drops is due to vhost holding onto the worker
barrier lock for too long in vhost_user_socket_read(). There are quite a
few of system calls inside the routine. At the end of the routine, it
unconditionally calls vhost_user_update_iface_state() for all message
types. vhost_user_update_iface_state() also unconditionally calls
vhost_user_rx_thread_placement() and vhost_user_tx_thread_placement().
vhost_user_rx_thread_placement scraps out all existing cpu/queue mappings
for the interface and creates brand new cpu/queue mappings for the
interface. This process is very disruptive and very expensive. In my
opinion, this area of code needs a makeover.

Fixes
-----
* vhost_user_socket_read() is rewritten that it should not hold
  onto the worker barrier lock for system calls, or at least minimize the
  need for doing it.
* Remove the call to vhost_user_update_iface_state as a default route at
  the end of vhost_user_socket_read(). There is only a couple of message
  types which really need to call vhost_user_update_iface_state(). We put
  the call to those message types which need it.
* Remove vhost_user_rx_thread_placement() and
  vhost_user_tx_thread_placement from vhost_user_update_iface_state().
  There is no need to repetatively change the cpu/queue mappings.
* vhost_user_rx_thread_placement() is actually quite expensive. It should
  be called only once per queue for the interface. There is no need to
  scrap the existing cpu/queue mappings and create new cpu/queue mappings
  when the additional queues becomes active/enable.
* Change to create the cpu/queue mappings for the first RX when the
  interface is created. Dont remove the cpu/queue mapping when the
  interface is disconnected. Remove the cpu/queue mapping only when the
  interface is deleted.

The create vhost user interface CLI also has some very expensive system
calls if the command is entered with the optional keyword "server"

As a bonus, This patch makes the create vhost user interface binary-api and
CLI thread safe. Do the protection for the small amount of code which is
thread unsafe.

bond: packet drops on VPP bond interface [VPP-1544]

We register callback for VNET_HW_INTERFACE_LINK_UP_DOWN_FUNCTION and
VNET_SW_INTERFACE_ADMIN_UP_DOWN_FUNCTION to add and remove the slave
interface from the bond interface accordingly. For static bonding without
lacp, one would think that it is good enough to put the slave interface into
the ective slave set as soon as it is configured. Wrong, sometimes the slave
interface is configured to be part of the bonding without ever bringing up the
hardware carrier or setting the admin state to up. In that case, we send
traffic to the "dead" slave interface.

The fix is to make sure both the carrier and admin state are up before we put
the slave into the active set for forwarding traffic.

VTL: vpp_papi_provider: Don't shortcircuit vpp_papi jasonfile detection.

The detection login in vpp_papi is significantly more advanced than
the implementation in vpp_papi_provider.

Let's take full advantage of it and ensure consistent behavior.

VTL:  Allow running simple unittest.TestCases.

It came to my attention that Ole added a simple test in:
https://gerrit.fd.io/r/#/c/16381/ and the framework forced him
to launch an instance of VPP to test the formatting of a mac address.

This change allows the test framework to run standard unittest.TestCases
without the need to spawn a VPP instance.

dpdk: show hardware may display the wrong information for rss active

Some dpdk driver does not support rte_eth_dev_rss_hash_conf_get. When that
happens, we display whatever that was in the stack variable for rss_hf which
is confusing.

The fix is to clear rss_hf prior to the call.

Given n equals to the maximum number of bytes to copy from src in the API,
