This patch implements the changes proposed in the deprecation
note[1]. Replace multiple color definitions in various places such as
rte_meter.h, rte_tm.h and rte_mtr.h with single rte_color defined
in rte_meter.h.
This is simple search and replace exercise without any implementation
change.

This patch implements the changes proposed in the deprecation
notes [1][2].
librte_mbuf changes:
The mbuf->hash.sched field is updated to support generic
definition in line with the ethdev traffic manager and meter APIs.
The new generic format contains: queue ID, traffic class, color.
Added public APIs to set and get these new fields to and from mbuf.
librte_sched changes:
In addtion, following API functions of the sched library have
been modified with an additional parameter of type struct
rte_sched_port to accommodate the changes made to mbuf sched field.
(i)rte_sched_port_pkt_write()
(ii) rte_sched_port_pkt_read_tree_path()
librte_pipeline, qos_sched UT, qos_sched app are updated
to make use of new changes.
Also mbuf->hash.txadapter has been added for eventdev txq,
rte_event_eth_tx_adapter_txq_set and rte_event_eth_tx_adapter_txq_get()
are updated to use mbuf->hash.txadapter.txq.
doc:
Release notes updated.
Removed deprecation notice for mbuf->hash.sched and sched API.

We use _GNU_SOURCE all over the place, but often times we miss
defining it, resulting in broken builds on musl. Rather than
fixing every library's and driver's and application's makefile,
fix it by simply defining _GNU_SOURCE by default for all
builds.
Remove all usages of _GNU_SOURCE in source files and makefiles,
and also fixup a couple of instances of using __USE_GNU instead
of _GNU_SOURCE.

The librte_sched uses rte_reciprocal to optimize division so, moving it to

Before this patch, the management of dependencies between directories
had several issues:
- the generation of .depdirs, done at configuration is slow: it can take
more than one minute on some slow targets (usually ~10s on a standard
PC without -j).
- for instance, it is possible to express a dependency like:
- app/foo depends on lib/librte_foo
- and lib/librte_foo depends on app/bar
But this won't work because the directories are traversed with a
depth-first algorithm, so we have to choose between doing 'app' before
or after 'lib'.
- the script depdirs-rule.sh is too complex.
- we cannot use "make -d" for debug, because the output of make is used for
the generation of .depdirs.
This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.
After this commit, "make config" is almost immediate.

The macro RTE_VERIFY always checks a condition.
It is optimized with "unlikely" hint.
While this macro is well suited for test applications, it is preferred
in libraries and examples to enable such check in debug mode.
That's why the macro RTE_ASSERT is introduced to call RTE_VERIFY only
if built with debug logs enabled.
A lot of assert macros were duplicated and enabled with a specific flag.
Removing these #ifdef allows to test these code branches more easily
and avoid dead code pitfalls.
The ENA_ASSERT is kept (in debug mode only) because it has more
parameters to log.

Irrelevant of the target, the preprocessor #ifdef SSE2 for the
grinder_pipe_exists function is inadequate since the __mm_testz_si128
function requires SSE4.1, PTEST instruction described in
https://en.wikipedia.org/wiki/SSE4#SSE4.1 (I do no have better spec
reference). I have bumped the preprocessor #ifdef to require SSE4.
The Atom N2600 does not have SSE4, http://ark.intel.com/products/58916,
and so I had trouble building rte_sched with optimized version of
grinder_pipe_exists, with following:
error: inlining failed in call to always_inline _mm_testz_si128’:
target specific option mismatch
GCC 4.9 correctly identifies my target as not having SSE4, and with
