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.

Since sig_tbl_bucket_size and key_tbl_key_size are explicitly aligned
at initialization, offset dereferences in the hash table code cannot
possibly be unaligned. However, the compiler is unaware of this fact
and complains on -Wcast-align. This patch modifies the code to use
RTE_PTR_ADD(), thereby silencing the compiler by casting through (void
*).

We use sequence numbers from a generator which has potentially started
long before the receiver. Therefore, the first number will typically
be > 0. The rte_reorder code will not work in this case, since the
packet is seen as outside of the buffer.
The patch instead records the first sequence number inserted as the
starting point.

Fix RTE_MBUF_METADATA macros to allow for unaligned accesses to
meta-data fields.
Forcing aligned accesses is not really required, so this is removing an
unneeded constraint.
This issue was met during testing of the new version of the ip_pipeline
application. There is no performance impact.
This change has no ABI impact, as the previous code that uses aligned
accesses continues to run without any issues.

The rte_eth_from_rings API allowed the creation of an ethdev port at
runtime using rte_rings as the underlying storage. However, the return
value from this function was either 0 or -1, and these values were never
actually documented in the API documentation. Unfortunately, the programmers
guide doc examples for this API implied that the return value from this
function was the port id of the newly created ethdev.
Since this latter behaviour is more useful - and already implied by the
documentation, this patch changes the return 0 to "return
data->port_id". It also adds in doxygen comments for the function so it
can be correctly documented in the API reference.

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.
