This is first part of addition of atomic macros with only macros for
__sync builtins.
- Based on earlier patch by Damjan (https://gerrit.fd.io/r/#/c/10729/)
Additionally
- clib_atomic_release macro added and used in the absence
of any memory barrier.
- clib_atomic_bool_cmp_and_swap added

This is the high version of extendto. This function accomplishes the
same task as both shuffling and extending done by SSE intrinsics.
This enables the NEON version for buffer indexes to buffer pointer
translation.

When calling vlib_buffer_clone() on a source vlib_buffer with no next
buffer but whose total_length_not_including_first_buffer hadn't been
properly zeroed out, the total_length_not_including_first_buffer of
the clone was set to a wrong value.

a crash on debug image (VPP-1151)
In debug image, there is extra code to validate the buffer when it is
freed. It uses the hash table to lookup the buffer index with spinlock
to prevent contention. However, there is one spinlock for each worker
thread. So allocating the buffer on thread-x and freeing the same buffer
on thread-y causes the validation to fail on thread-y. The fix is to
have only one spinlock, stored in vlib_global_main.

Currently, every alloc involves callback function call. With this change
callback function is called only if there is no empty buffers on the
free list.

This change avoids hitting
ASSERT (vec_len (f->buffers) == f->n_alloc);
in vlib_buffer_delete_free_list_internal by updating
vlib_buffer_free_list_t->n_alloc in case when buffers are removed from
the free list due to overfill.

To save space in the first cacheline following is changed:
- total_length_not_including_first_buffer moved to the 2nd cacheline.
This field is used only when VLIB_BUFFER_TOTAL_LENGTH_VALID and
VLIB_BUFFER_NEXT_PRESENT are both set.
- free_list_index is now stored in 4bits inside flags, which
allows up to 16 free lists. In case we need more we can store index
in the 2nd cachelin

- vnet_buffer_pool_create should probably be named
dpdk_buffer_pool_create since that is what it does.
- Its prototype should also be in a DPDK plugin header, not in
vlib/buffer_funcs.h, since the implementation is in the plugin
and nobody else should be calling it.

Currently, buffer index is calculated as a offset to the physmem
region shifted by log2_cacheline size.
When DPDK is used we "hack" physmem data with information taken from
dpdk mempool. This makes physmem code not usable with DPDK.
This change makes buffer memory start and size independent of physmem
basically allowing physmem to be used when DPDK plugin is loaded.

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.
