use C linkage where appropriate in headers

Assure that 'extern "C" { /../ }' do not cover files included from a
particular header file, and address minor issues resulting from this
change of order.

Dealing with C++ should delegate to the individual include file level,
rather than being imposed by the user of that file. For example,
forcing C linkage prevents __Generic macros being replaced with
overloaded static inline functions in C++ translation units.

Eliminate 'extern "C"' from files which do not declare any symbols
(e.g., only macros or struct types).

On the other hand, the headers check is too naive in assuming that all
headers must contain a 'extern "C"'. Such a check was added in commit
1ee492bdc4ff ("buildtools/chkincs: check missing C++ guards").
Since this current change results in many headers not containing such
a token, remove the check for 'extern "C"' until we have a better
implementation.

examples: move alignment attribute on types for MSVC

Move location of __rte_aligned(a) to new conventional location. The new
placement between {struct,union} and the tag allows the desired
alignment to be imparted on the type regardless of the toolchain being
used for both C and C++. Additionally, it avoids confusion by Doxygen
when generating documentation.

examples/qos_sched: use bigger bursts on dequeue

While performance of the QoS block drops sharply if the dequeue size is
greater than or equal to the enqueue size, increasing the dequeue size
to just under the enqueue one gives improved performance when the

examples/qos_sched: remove Tx buffering

Since the qos_sched app does batch dequeues from the QoS block, there is
little point in trying to batch further in the app - just send out the
full burst of packets that were received from the QoS block. With modern
CPUs and write-combining doorbells, the cost of doing smaller TX's is
reduced anyway for the worst case.

Latest mbuf changes (priv_size addition and related fixes)
exposed small problem with testpmd and few other sample apps:
when mbuf size is exaclty 2KB or less, that causes
ixgbe PMD to select scattered RX even for configs with 'normal'
max packet length (max_rx_pkt_len == ETHER_MAX_LEN).
To overcome that problem and unify the code, new macro was created
to represent recommended minimal buffer length for mbuf.
When appropriate, samples are updated to use that macro.
