Fifos can use multiple memory chunks for simple read/write operations.
Adding/removing chunks after assignment not yet supported.

Problems Addressed:
- Contention of cursize by producer and consumer.
- Reduce the no of modulo operations.
Changes:
- Synchronization between producer and consumer changed from cursize
to head and tail indexes
Implications: reduces the usable size of fifo by 1.
- Using weaker memory ordering C++11 atomics to access head and tail
based on producer and consumer role.
- Head and tail indexes are unsigned 32 bit integers. Additions and
subtraction on them are implicit 32 bit Modulo operation.
- Adding weaker memory ordering variants of max_enq, max_deq, is_empty
and is_full Using them appropriately in all places.
Perfomance improvement (iperf3 via Hoststack):
iperf3 Server: Marvell ThunderX2(AArch64) - iperf3 Client: Skylake(x86)
~6%(256 rxd/txd) - ~11%(2048 rxd/txd)

nonexistent elements
If we are testing for an index whose membership bitmask happens to sit in LSB of uword,
and there is nothing else set in that uword in the member bitmask, the shortcut path
returning the valid index is taken even if the element with a given index doesn't
exist in the sparse vector. This happens because the count of leading zeroes on the
value of 0 is zero, which is equal to the value taken modulo bitsize uword.
Take care of that case.
Also add unittests showing the problem and verifying that sparse_vec_index2 does not
have the same issue.

A punt/exception path that provides:
1) clients that use the infra
2) clients can create punt reasons
3) clients can register to recieve packets that are punted
for a given reason to be sent to the desired node.
4) nodes which punt packets fill in the {reason,protocol} of the
buffere (in the meta-data) and send to the new node "punt-dispatch"
5) punt-dispatch sends packets to the registered nodes or drops

Me: "Mr Coverity, I thought I fixed the dead code warning just few days ago in
this file. Why are you still complaining about the same stuff to me?"
Mr. Coverity: "Duh! But you are supposed to fix all occurences in the same file."
Me: "Mr. Coverity, I didn't see you flag the warning in the other places last
time?"
Mr. Coverity: "Shh! That is the secret of my dark side!"

Coverity complains about dead code as shown below and it is right.
The fix is to simply remove the dead code.

For some reason, GCC 8 in debian is pickier than GCC 8 in ubuntu. It complains
about things in strncpy like this
/home/sluong/vpp/src/vlib/linux/pci.c:485:7: error: ‘strncpy’ output may be
truncated copying 15 bytes from a string of length 255 [-Werror=stringop-truncation]
strncpy (ifr.ifr_name, e->d_name, sizeof (ifr.ifr_name) - 1);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/home/sluong/vpp/src/vlib/linux/pci.c: At top level:
It also complains similar things in string_test.c
The fix in pci.c is to convert strncpy to use clib_strncpy
The fix in string_test.c is condiational compile the complained code for GCC 8.

Given n equals to the maximum number of bytes to copy from src in the API,
or the rough estimate strlen of src, strncpy_s_inline should not copy more
than the number of bytes, computed by strlen(src), to dst if n is greater than
strlen(src). The number of bytes to copy is computed by strnlen(src,n), not n.
