The patch c344eab3ee has moved the hardware definition of CPU flags.
Now the functions checking these hardware flags are also moved.
The function rte_cpu_get_flag_enabled() is no more inline.
The benefits are:
- remove rte_cpu_feature_table from the ABI (recently added)
- hide hardware details from the API
- allow to adapt structures per arch (done in next patch)

If eth_ring vdevs are created from the command line with the --vdev option,
they create their own rings which are not shared by other vdevs.
Some of tests in this suite require that the vdevs share rings, so some
of the tests fail.
For vdevs to share rings they must be created in the test code with the
rte_eth_from_rings() function using rings created with the rte_ring_create()
function.
Use the command line option --vdev=eth_ring0 to create port 0.
This option is not mandatory for the tests to pass. It allows some additional
functional tests on cmd-line created rings to be executed.
Create two rings and five ethdevs in test_pmd_ring.c for ports 1 to 5,
and then use these to run the unit tests on the pmd ring functionality.
Improve test output by adding the port number to printf statements,
and adding a printf describing each test.

testpmd> set txsplit rand
testpmd> start
After some time TX on ixgbe queue will hang,
and all packet transmission on that queue will stop.
This bug was first reported and investigated by
Vlad Zolotarov <vladz@cloudius-systems.com>:
"We can reproduce this issue when stressed the xmit path with a lot of highly
fragmented TCP frames (packets with up to 33 fragments with non-headers
fragments as small as 4 bytes) with all offload features enabled."
The root cause is that ixgbe_xmit_pkts() in some cases violates the HW rule
that the distance between TDs with RS bit set should not exceed 40 TDs.
>From the latest 82599 spec update:
"When WTHRESH is set to zero, the software device driver should set the RS bit
in the Tx descriptors with the EOP bit set and at least once in the 40
descriptors."
The fix is to make sure that the distance between TDs with RS bit set
would never exceed HW limit.
As part of that fix, tx_rs_thresh for ixgbe PMD is not allowed to be greater
then to 32 to comply with HW restrictions.
With that fix slight slowdown for the full-featured ixgbe TX path
might be observed (from our testing - up to 4%).
ixgbe simple TX path is unaffected by that patch.

If using multiple cores on a system with hardware transactional
memory support, thread scaling does not work, as there was a single
point in the hash library which is a bottleneck for all threads,
which is the "free_slots" ring, which stores all the indices of
the free slots in the table.
This patch fixes the problem, by creating a local cache per logical core,
which stores locally indices of free slots,
so most times, writer threads will not interfere each other.

[Thomas: remove unused PKT_BURST_SZ]
Add new timer-manage race-condition test: We wrote a test to confirm
our suspicion that we could crash rte_timer_manage() under the right
circumstances. We repeatedly set several timers to expire at roughly
the same time on the master core. The master lcore just delays and runs
rte_timer_manage() about ten times per second. The slave lcores all
watch the first timer (timer-0) to see when rte_timer_manage() is
running on the master, i.e., timer-0's state is not PENDING.
At this point, each slave attempts to reset a subset of the timers to
a later expiration time. The goal here is to have the slaves moving
most of the timers to a different place in the master's pending-list,
while the master is traversing the same next-pointers (the slaves'
sl_next[0] pointers) and running callback functions. This eventually
results in the master traversing a corrupted linked-list.
In our observations, it results in an infinite loop.

Fix app/test timer stress test 2: Sometimes this test fails and
seg-faults because the slave lcores get out of phase with the master.
The master uses a single int, 'ready', to synchronize multiple slave
lcores through multiple phases of the test.
To resolve, we construct simple synchronization primitives that use one
atomic-int state variable per slave. The master tells the slaves when to
start, and then waits for all of them to finish. Each slave waits for
the master to tell it to start, and then tells the master when it has
finished.
