trace: introduce new subsystem

Define the public API for trace support.
This patch also adds support for the build infrastructure and
update the MAINTAINERS file for the trace subsystem.

The 8 bytes tracepoint object is a global variable, and can be used in
fast path. Created a new __rte_trace_point section to store the
tracepoint objects as,
- It is a mostly read-only data and not to mix with other "write"
  global variables.
- Chances that the same subsystem fast path variables come in the same
  fast path cache line. i.e, it will enable a more predictable
  performance number from build to build.

and implement it for Linux and FreeBSD.

compress/qat: support IM buffer too small operation

This patch implements a special way of buffer handling when internal
QAT IM buffer is too small for Huffman dynamic compression operation.
Instead of falling back to fixed compression, the operation is now
split into multiple smaller dynamic compression requests (possible to
execute on QAT) and their results are then combined and copied into
the output buffer. This is not possible if any checksum calculation
was requested - in such case the code falls back to fixed compression
as before.

eal/windows: do not expose private facilities

The goal of rte_os.h is to mitigate OS differences for EAL users.
In Windows EAL, rte_os.h did excessive things:

1. It included platform SDK headers (windows.h, etc). Those files are
   huge, require specific inclusion order, and are generally unused by
   the code including rte_os.h. Declarations from platform SDK may
   break otherwise platform-independent code, e.g. min, max, ERROR.

2. It included pthread.h, which is clearly not always required.

3. It defined functions private to Windows EAL.

Reorganize Windows EAL includes in the following way:

1. Create rte_windows.h to properly import Windows-specific facilities.
   Primary users are bus drivers, tests, and external applications.

2. Remove platform SDK includes from rte_os.h to prevent breaking
   otherwise portable code by including rte_os.h on Windows.
   Copy necessary definitions to avoid including those headers.

3. Remove pthread.h include from rte_os.h.

4. Move declarations private to Windows EAL into eal_windows.h.

test/malloc: run realloc tests on external heap

Due to the fact that the rte_realloc() test depends on the layout of
underlying memory, it can sometimes fail due to fragmentation of the
memory. To address this, make it so that the realloc autotests are run
using a newly created external memory heap instead of main memory.

ring: introduce peek style API

For rings with producer/consumer in RTE_RING_SYNC_ST, RTE_RING_SYNC_MT_HTS
mode, provide an ability to split enqueue/dequeue operation
into two phases:
- enqueue/dequeue start
- enqueue/dequeue finish
That allows user to inspect objects in the ring without removing
them from it (aka MT safe peek).

ring: introduce HTS ring mode

Introduce head/tail sync mode for MT ring synchronization.

ring: introduce RTS ring mode

Introduce relaxed tail sync (RTS) mode for MT ring synchronization.
Aim to reduce stall times in case when ring is used on
overcommited cpus (multiple active threads on the same cpu).
The main difference from original MP/MC algorithm is that
tail value is increased not by every thread that finished enqueue/dequeue,
but only by the last one.
That allows threads to avoid spinning on ring tail value,
leaving actual tail value change to the last thread in the update queue.

ring: prepare ring to allow new sync schemes

To make these preparations two main things are done:
- Change from *single* to *sync_type* to allow different
  synchronisation schemes to be applied.
  Mark *single* as deprecated in comments.
  Add new functions to allow user to query ring sync types.
  Replace direct access to *single* with appropriate function call.
- Move actual rte_ring and related structures definitions into a
  separate file: <rte_ring_core.h>. It allows to refer contents
  of <rte_ring_elem.h> from <rte_ring.h> without introducing a
  circular dependency.
