eal: add and use unaligned integer types

On machines that are strict on pointer alignment, current code breaks
on GCC's -Wcast-align checks on casts from narrower to wider types.
This patch introduces new unaligned_uint(16|32|64)_t types, which
correctly retain alignment in such cases.  Strict alignment
architectures will need to define CONFIG_RTE_ARCH_STRICT_ALIGN in
order to effect these new types.

fm10k: fix mac/vlan filtering

This patch includes 3 changes related to MAC/VLAN address table
when the system (e.g. testpmd) is started and closed:
 - remove default MAC address with fixed VLAN 0 which was for the
   debug purpose before the MAC/VLAN filter function was implemented.
 - enable VF MAC/VLAN filter for the first valid MAC address
   and first valid VLAN ID. This is needed for system (e.g. testpmd)
   to setup default MAC address and default VLAN for VF.
   Later attempt to change these default value will be refused by
   under layer shared code and PF host functions.
 - un-register any combination of VLAN and MAC address from fm10k
   switch side MAC table when the system (e.g. testpmd) is closed.

 - mailbox timeout.

Vring enqueue need consider the 2 cases:
 1. use separate descriptors to contain virtio header and actual data,
    e.g. the first descriptor is for virtio header, and then followed
    by descriptors for actual data.
 2. virtio header and some data are put together in one descriptor,
    e.g. the first descriptor contain both virtio header and part of
    actual data, and then followed by more descriptors for rest of packet
    data, current DPDK based virtio-net pmd implementation is this case;

So does vring dequeue, it should not assume vring descriptor is chained

or not. This patch also fixes TX corrupt issue when vhost co-work with

rte_jhash is basically like __rte_jhash_2hashes but
it returns only 1 hash, instead of 2.

passing 0 as the second seed and returning just the first hash value.
(performance penalty is negligible)

The same is done with rte_jhash2. Also, rte_jhash2 is just an specific case
where keys are multiple of 32 bits, and where no key alignment check is required.
