Moved code to the ethernet input node, and the interface output
path(s). Since we no longer skip ethernet-input, there's no reason
for device drivers to know anything about pcap rx tracing, etc.

Rewrite vlib_buffer_chain_linearize function so that it works as intended.
Linearize buffer chains coming out of reassembly to work around some
dpdk-tx issues. Note that this is not a complete workaround
as a sufficiently large packet will still cause the resulting chain to
be too long.
Drop features from reassembly code which relies on knowing which and how
many buffers were freed during linearization, buffer counts and tracing
capabilities for these cases.

Some x86 CPUs have IOMMU capable dealing only with 39-bit address space
This patch also adds option to specify physmem base address from

The main thread squirrels away vlib_time_now (&vlib_global_main),
worker threads use it to calculate an offset in f64 seconds from their
own vlib_time_now(vm) value. We use that offset until the next barrier
sync.
Thanks to Damjan for the suggestion.

It is causing compilation sloness with gcc-7 so removing it
before it was originally planned.
So far macros are left in the tree so we can know which nodes to
convert to new multiarch code.

The assert allows easier debugging in gdb by aborting instead of exiting
cleanly. Also a core is generated so a stack trace can be obtained.

This patch introduces following changes:
- deprecated free lists which are not used and not compatible
with external buffer managers (i.e. DPDK)
- introduces native support for per-numa buffer pools
- significantly improves performance of buffer alloc and free

Add missing pre-input node runtime fork and refork code.
unix-epoll-input runs on all threads; each instance needs its own

As a FUD reduction measure, this patch implements 2-way parallel
counter collection. Synthetic stat component counter pairs run at the
same time. Running two counters (of any kind) at the same time
naturally reduces the aggregate time required by an approximate
factor-of-2, depending on whether an even or odd number of stats have
been requested.
I don't completely buy the argument that computing synthetic stats
such as instructions-per-clock will be inaccurate if component counter
values are collected sequentially. Given uniform traffic pattern, it
must make no difference.
As the collection interval increases, the difference between serial
and parallel component counter collection will approach zero, see also
the Central Limit theorem.

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.

The code that was manipulating interface names with ifreq was
causing warnings about possible truncation and non terminated
strings.
These are warnings only since kernel would allow a interface
name > 15 characters anyway.

Doing strncpy(ifr.ifr_name, s, sizeof(ifr.ifr_name)) will cause
a warning about string truncation with GCC 8 (and other tools).
Fix this by using sizeof(ifr.ifr_name) - 1. Also, there is no
need to manually zero the end of the string since the whole
ifr structure is already zeroed by memset.

It's not OK to crash due to a transient buffer allocation failure.
Return 1 if the requested operation failed, otherwise 0.
Buffer index parameter change to a value-result, so the caller can
differentiate between partial and complete allocation failure: callers
which request an initial allocation (inbound bi = ~0) need to check
the (out) value to decide whether or not to call vlib_buffer_free(...).

This patch adds support for VMBus to the VPP infrastructure.
Since the only device that matters is the netvsc Poll Mode Driver
in DPDK, the infrastructure is much simpler than PCI.
