Change rte_mempool_populate_iova() and rte_mempool_populate_virt() to
return 0 instead of -EINVAL when there is not enough room to store one
object, as it can be helpful for applications to distinguish this
specific case.
As this is an ABI change, use symbol versioning to preserve old
behavior for binary applications.

There is a common macro __rte_unused, avoiding warnings,

Mempool ops may register in different order when compiling. The default
ops index is always zero but the wanted ops is ring_mp_mc. This patch
sets best mempool ops before generating mbuf pool to fix this issue.

With the API and ABI freeze ahead, it will be good to reserve
some bits on the private structure for future use.
Otherwise we will potentially need to maintain two different
private structure during 2020 period.
There is already one use case for those reserved bits[1]
The reserved field should be set to 0 by the user.

Some versions of pkg-config don't support the --path flag, which is not a
fatal error when building the apps. Without the flag, the makefile just
cannot track the .pc file of DPDK as a dependency of the build. Therefore,
we can ignore the error and suppress it by redirecting to /dev/null the
stderr from that call to pkg-config.

Not all versions of pkg-config in distros have support for the
--define-prefix flag [1], causing errors when building examples manually or
with test-meson-builds.sh script [2].
For the former case, we need to remove the hard-coded use of the flag in
the Makefiles.
For the latter case, the flag is necessary for builds to succeed, so we
skip the tests when it's not present, passing it as part of the pkg-config
command if it is supported.

Enable an example for rawdev ntb. Support interactive mode to send
file on one host and receive file from another host. The command line
would be 'send [filepath]' and 'receive [filepath]'.
But since the FIFO is not enabled right now, use rte_memcpy as the enqueue
and dequeue functions and only support transmitting file no more than 4M.
