Same as rte_vhost_enqueue_burst we should cast used->idx
to volatile before notify guest.

I forgot to copied rte_eal_version.map, added on new patchset.
OSv supports shared libraries, but I found that DPDK shared libraries
causes an error on OSv:
https://github.com/cloudius-systems/osv/issues/599
I'll fix it shortly.

Since OSv is written in C++, we need to write OSv EAL in C++.
To do so, we need to compile .cc files by $(CXX).
This patch does not contain diff for clang and icc, but OSv EAL does not
supported these toolchain, this is enough for now.

When failed to malloc buffer from mempool we just update last_used_idx but
not used->idx so after many times vhost thought have handle all packets
but virtio_net thought vhost have not handle all packets and will not
update avail->idx.

Hi Pawel,
Oops, thanks for the clue. I have a buffer over-read here leading to undefined
behaviour.
The only solution I see here is to declare uint32_t pointer and evaluate it to
(uint8_t *) data + data_len - (data_len & 0x07). Ideas are welcome. That would
resolve strict-aliasing violation.
