- mheap is not used anymore for buffer allocation
- simple bitmap bassed buffer alloc scheme is introduced

Queue RPC calls and send them from the main dispatch loop. As things stood,
if the vpp main input queue filled, worker threads could enter a
barrier-sync spin-wait in the middle of processing a frame. If thread
0 decided to recreate worker thread data structures, the worker thread(s)
could easily crash.
Legislate the problem out of existence by enqueueing RPC messages only
from the main dispatch loop. At that point, doing a barrier-sync wait
is perfectly OK.

Change the rebuilding of worker thread clone datastructures
to run in parallel on the workers, instead of serially
on main.

- refactor existing congestion control code (RFC 6582/5681). Handling of ack
feedback now consists of: ack parsing, cc event detection, event handling,
congestion control update
- extend sack scoreboard to support sack based retransmissions
- basic implementation of Eifel detection algorithm (RFC 3522) for
detecting spurious retransmissions
- actually initialize the per-thread frame freelist hash tables
- increase worker stack size to 2mb
- fix session queue node out-of-buffer handling
- ensure that the local buffer cache vec_len matches reality
- avoid 2x spurious event requeues when short of buffers
- count out-of-buffer events
- make the builtin server thread-safe
- fix bihash template threading issue: need to paint -1 across uninitialized
working_copy_length vector elements (via rebase from master)

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.

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

Clean up spurious binary API client link dependency on libvlib.so,
which managed to hide behind vlib_mains == 0 checks reached by
VLIB_xxx_FUNCTION macros.
