Extend port_id definition from uint8_t to uint16_t in lib and drivers
data structures, specifically rte_eth_dev_data. Modify the APIs,
drivers and app using port_id at the same time.
Fix some checkpatch issues from the original code and remove some
unnecessary cast operations.
release_17_11 and deprecation docs have been updated in this patch.

Exported header files used by applications should allow the strictest
compiler flags. Language extensions used in many places must be explicitly
marked or removed to avoid warnings and compilation failures.
This commit prevents the following errors:
error: type of bit-field `[...]' is a GCC extension
Note: the standard does not require implementations to issue a diagnostic
message with these, and such errors do not occur with recent GCC or clang
versions. However, GCC 4.7 is still common and using the extension keyword
is easier than checking compiler version.

Function like 'rte_kni_rx_burst()' keeps
allocating 'MAX_MBUF_BURST_NUM' mbufs to
kni fifo queue unless the queue's capacity
('KNI_FIFO_COUNT_MAX') is reached. So, if
the mempool is under-provisioned, user may
run into "Out of Memory" logs from KNI code.
This commit documents the need to provision
mempool capacity of more than
"2 x KNI_FIFO_COUNT_MAX" for each KNI interface.

When a KNI object is created, a name is assigned to it which is stored
internally. There is also an API function to look up a KNI object by
name, but there is no API to query the current name of an existing
KNI object. This patch adds just such an API.

The file rte_kni.h depends upon a number of other headers, some of which
are missing from the #include lines. The following #includes are added:
* rte_memory.h - for the definition of phys_addr_t
* rte_mempool.h - for the definition of mempool struct and the mempool
create function.

The kni header file includes the mbuf header file, but it does not
need to do so as it only uses pointers to the struct rte_mbuf type, and
does not use any of the mbuf internals, nor any of the mbuf functions or
macros. Therefore the inclusion is unnecessary, and can be replaced by a
forward declaration of the mbuf type.

The previous implementation of rte_kni_alloc() was allocating memzones with a
name composed of a fixed string and the interface name. When an application was
allocating and deallocating multiple interfaces with different names, memzones
were quickly exhausted, even though memzones from deallocated interfaces were
never used anymore (unless an interface with the same name was re-allocated).
As a result, the application was unable to allocate more KNI interfaces with
different names.
This patch implements the KNI memzone pool in order to prevent memzone
exhaustion when allocating/deallocating KNI interfaces. It adds a new API call,
rte_kni_init(max_kni_ifaces) that shall be called before any call to
rte_kni_alloc() if KNI is used. The memzones are pre-allocated with interface-
independent names so that they can be reused.

This commit removes trailing whitespace from lines in files. Almost all
files are affected, as the BSD license copyright header had trailing
whitespace on 4 lines in it [hence the number of files reporting 8 lines
changed in the diffstat].
