Configure w/ --enable-dlmalloc, see .../build-data/platforms/vpp.mk
src/vppinfra/dlmalloc.[ch] are slightly modified versions of the
well-known Doug Lea malloc. Main advantage: dlmalloc mspaces have no
inherent size limit.

This is ~50% improvement in buffer alloc performance.
For a 256 buffer allocation, it was ~10 clocks/buffer, now is < 5 clocks.

- buffer_main is no longer part of vlib_main_t
- pool of free lists is still part of vlib_main_t
- mheap is not used anymore for buffer allocation
- simple bitmap bassed buffer alloc scheme is introduced

We don't need per vlib_main physmem_main, so keep it separatelly instead
of trying to keep them in sync.

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.

It's way too easy to imagine leaving a mutex or a spin-lock held in
the /vpe-api shared-memory segment, or elsewhere. Set a volatile
variable and check it in a safe place...

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

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.
