It should be OK to scrape dispatch stats without forcing a barrier
sync. Scrape the stats manually. We'll see what happens.

- use types on the DHCP API so that the same data is sent in comfing messages and in dumps
- add the DHCP client dump API
- update VOM to refelct API changes
- rename VOM class dhcp_config* dhcp_client*
- the VOM dhcp_client class maintains the lease data (which it reads on a dump) for clients to read

Logging previously used a string name for the log level and changed
the system-wide log level based on this string name. It now uses a
logging-module provided constant for the log level and changes its own
logger's level based on the name, and only if the level is provided.
This allows the logging to be more compatible with Pythonic usage,
where an external source may be used to dictate logging levels across
the system on a per module basis and should not be overridden.

- Modify the API send_ip6_na and send_ip4_garp to take sw_if_index instead
of vnet_hw_interface_t and add call to build_ethernet_rewrite to support
subinterface/vlan
- Add code to bonding driver to send an event to bond_process when the first
interface becomes active or when the active interface is down
- Create a bond_process to walk the interface and the corresponding
subinterfaces to send garp/ip6_na when an event is received.
- Minor cleanup in bonding/node.c
Note: dpdk bonding driver does not send garp/ip6_na for subinterfaces. There is
no attempt to fix it here. But the infra is now done and should be easy to
add the support.

if you plan to put a hash into shared memory, the key sum and key
equal functions MUST be set to constants such as KEY_FUNC_STRING,
KEY_FUNC_MEM, etc. -lvppinfra is PIC, which means that the process
which set up the hash won't have the same idea where the key sum and
key compare functions live in other processes.

Added configure argument "--with-log2-cache-line-bytes=5|6|7|auto"
AKA 32, 64, or 128 bytes, or use the inferred value from the build host.
produces build-xxx/vpp/vppinfra/config.h, which .../src/vppinfra/cache.h
Kernels which implement the following pseudo-file (aka x86_64) are
easy: /sys/devices/system/cpu/cpu0/cache/index0/coherency_line_size
Otherwise, extract the cpuid from /proc/cpuinfo and map it to the
cache line size.

- implement a 1us purgatory for the session structures
by adding a special connection list, where all connections
about to be deleted go.
- add per-list-head timeouts updated upon the list enqueue/dequeue
for connection idle management
- add a "unused" session list with list ID#0, which should
never be used unless there is a logic error. Use this ID
to initialize the sessions.
- improve the maintainability of the session linked list
structures by using symbolic bogus index name instead of ~0
- change the ordering of session creations - first reverse, then
local. To minimize the potential for two workers competing for
the same session in the corner case of the two packets
on different workers creating the same logical session
- reduce the maximum session count to keep the memory usage the same
- add extra log/debug/trace to session cleaning logic
- be more aggressive with cleaning up sessions - wind up the
interrupts from the workers to themselves if there is more
work to do

If the caller is the session owning thread or the main thread with a
worker barrier sync (cli/api) add an event to the pending disconnects
vector in the session node and entirely avoid using the event queue.
Useful for bursts of disconnects (like an app detach).
If disconnects come from a processes, be willing to retry enqueueing the
disconnect to the event queue multiple times.

show "no" under the age column to indicate entry does not age.

Prior to the change, dpdk plugin assumes xd->device_index is
used both as index for internal dpdk_main->devices array
and DPDK port index to call into DPDK APIs.
However, when running on top of Failsafe PMDs,
DPDK port index range may no longer be contiguous (as noted:
http://dpdk.org/ml/archives/dev/2018-March/092375.html
for related changes in DPDK). Because this, dpdk plugin can
no longer iterate through all available DPDK ports
with a for 0->rte_eth_dev_count() loop and the assumption of
device_index no longer holds.
This is part of initial effort to enable vpp running over
dpdk on failsafe PMD in Microsoft Azure(3/4).
