FreeBSD doesn't offer epoll, but an implementation which uses kqueue is
available as an external library. On FreeBSD in subsystems which require
epoll have cmake look for libepoll-shim.

Add support for adding Linux and FreeBSD specific sources to
add_vpp_library and support for installing Linux specific headers. Don't
add support for FreeBSD specific headers until we have some to install.

This patch introduces DMA infrastructure into vlib. This is well known
that large amount of memory movements will drain core resource. Nowadays
more and more hardware accelerators were designed out for freeing core
from this burden. Meanwhile some restrictions still remained when
utilizing hardware accelerators, e.g. cross numa throughput will have a
significant drop compared to same node. Normally the number of hardware
accelerator instances will less than cores number, not to mention that
applications number will even beyond the number of cores. Some hardware
may support share virtual address with cores, while others are not.
Here we introduce new DMA infrastructure which can fulfill the
requirements of vpp applications like session and memif and in the
meantime dealing with hardware limitations.
Here is some design backgrounds:
Backend is the abstract of resource which allocated from DMA device
and can do some basic operations like configuration, DMA copy and
result query.
Config is the abstract of application DMA requirement. Application
need to request an unique config index from DMA infrastructure. This
unique config index is associated with backend resource. Two options
cpu fallback and barrier before last can be specified in config.
DMA transfer will be performed by CPU when backend is busy if cpu
fallback option is enabled. DMA transfer callback will be in order
if barrier before last option is enabled.
We constructs all the stuffs that DMA transfer request needed into
DMA batch. It contains the pattern of DMA descriptors and function
pointers for submission and callback. One DMA transfer request need
multiple times batch update and one time batch submission.
DMA backends will assigned to config's workers threads equally. Lock
will be used for thread-safety if same backends assigned to multiple
threads. Backend node will check all the pending requests in worker
thread and do callback with the pointer of DMA batch if transfer
completed. Application can utilize cookie in DMA batch for selves
usage.
DMA architecture:

| Config1 | | Config2 | | Config1 | | Config2 |

Function call in this case is not bad thing, as those functions
are called once per frame.

Instead of allocating stack from the main heap, this patch mmaps stack
memory together with guard page.
This aproach reduces main heap usage, and stack memory is prefaulted
on demand, so bigger process stacks will have zero impact on memory
usage as long as stack memory is not needed for real.
In addition, it fixes issue with systems which have bigger default page
size (observed with 65536).

Support for startup node multi-arch variant selection through startup.conf.
This is to facilitate unit, functional testing and benchmarking of non-default
multi-arch variant node code path. Also added parameters to make test, to
specific using multi-arch variants in unit testing.

When configured at compile time via the cmake
VPP_BUFFER_FAULT_INJECTOR option, the buffer allocator will appear to
fail a certain fraction of the time.
By default, the allocator succeeds 80% of the time. Detailed command
line configuration options are available, but only when the image has
been compiled with cmake option described above:
vlib { buffer-alloc-success-rate [0.0 ... 1.0]
buffer-alloc-success-seed <nnnn> }
Modify vlib_buffer_pool_create(...) so 0 is always an invalid buffer
index.
Debug images: add checks for bad buffer index enqueues, and also
verify that f->n_vectors doesn't accidentally map one or more
instances of the frame poison pattern 0xfefefefe.

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

The core VLIB library now has a means to dispoe of buffers.
the vlib punt/drop node counts node errors.
the vnet punt/drop node counts interface errors.
speed up both nodes with the usual reciepe.
before:
error-drop 8.33e1
after:
drop 4.51e1
error-drop 6.81e0

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.
