It looks better to have a data buffer address that is aligned to
8 bytes. This is the case when there is no mbuf private area, but
if there is one, the alignment depends on the size of this area
that is located between the mbuf structure and the data buffer.
Indeed, some drivers expects to have the buffer address aligned
to an even address, and moreover an unaligned buffer may impact
the performance when accessing to network headers.
Add a check in rte_pktmbuf_pool_create() to verify the alignment
constraint before creating the mempool. For applications that use
the alternative way (direct call to rte_mempool_create), also
add an assertion in rte_pktmbuf_init().
By the way, also add the MBUF log type.

librte_pmd_mlx4.so needs to be linked with libibverbs otherwise, the PMD is
not able to open Mellanox devices and the following message is printed by
testpmd at startup
"librte_pmd_mlx4: cannot access device, is mlx4_ib loaded?".
Applications dependency on libibverbs are moved to be only valid in static
mode, in shared mode, applications do not depend on it anymore,
librte_pmd_mlx4.so keeps this dependency and thus is linked with libibverbs.
MLX4 cannot be supported in combined shared library because there is no clean
way of adding -libverbs to the combined library.

This patch fixes the issue:
Testpmd crashed with Segmentation fault when setup tx queues on vf
Steps for reproduce:
- create one vf device from i40e driver
- bind vf device to igb_uio and start testpmd
With debugging tools, we saw the struct i40e_vf is cleared after
memcpy(&dev->data->dev_conf, dev_conf, sizeof(dev->data->dev_conf)) in
rte_eth_dev_configure, which should not happen, and the pointer to
i40e_vf isn't in the range of i40e_adapter.
The root cause is the dev_private_size in i40e virtual function driver
struct rte_i40evf_pmd was set incorrectly.

The patch demonstrates how to handle per rx queue interrupt in a NAPI-like
implementation in userspace. The working thread mainly runs in polling mode
and switch to interrupt mode only if there is no packet received in recent polls.
The working thread returns to polling mode immediately once it receives an
interrupt notification caused by the incoming packets.
The sample keeps running in polling mode if the binding PMD hasn't supported
the rx interrupt yet. Now only ixgbe(pf/vf) and igb support it.
