service: add attribute for number of invocations

This commit adds a new attribute to the service cores attributes
API, which allows the application to retrieve the number of times
that a service-core called the service to perform its action.

bus/pci: fix interrupt handler type

For virtio legacy device, testpmd startup fails when using uio_pci_generic.

The issue is caused by invoking the function pci_ioport_map. The correct
value of intr_handle.type is already set before calling it, we should avoid
overwriting the default value "RTE_INTR_HANDLE_UNKNOWN" in this function.
Besides, the removal has no harm to other cases because it is set to 0 by a
memset on the whole struct during allocation in the function pci_scan_one.

Such assignments are removed in the meanwhile in pci_uio_map_resource(),
pci_vfio_map_resource_primary() and pci_vfio_map_resource_secondary() in
order to keep consistencies and avoid future questions.

service: fix service core launch

This patch fixes a potential bug, which was not consistently
showing up in the unit tests. The issue was that the service-
lcore being started was not in a "WAIT" state, and hence EAL
would return -EBUSY instead of launching the lcore.

In order to ensure a core is in a launch-ready state, the application
must call rte_eal_wait_lcore, to ensure that the core has completed
its previous task, and that EAL is ready to re-launch it.

The call to rte_eal_wait_lcore() is explicitly not in the
service core function, to make it visible to the application.
Requiring an explicit function call ensures the developer sees
that a lcore could block in the rte_eal_wait_lcore() function
if the core hasn't returned from its previous function.

From a usability perspective, hiding the wait_lcore() inside
service cores would cause confusion.

This patch adds rte_eal_wait_lcore() calls to the unit tests,
to ensure that the lcores for testing functionality are ready
to run the test.

license: introduce SPDX identifiers

The DPDK uses the Open Source BSD-3-Clause license for the core libraries
and drivers. The kernel components are naturally GPLv2 licensed.

Many of the files in the DPDK source code contain the full text of the
applicable license. For example, most of the BSD-3-Clause files contain a
full copy of the BSD-3-Clause license text.

Including big blocks of License headers in all files blows up the source
code with mostly redundant information.  An additional problem is that even
the same licenses are referred to by a number of slightly varying text
blocks (full, abbreviated, different indentation, line wrapping and/or
white space, with obsolete address information, ...) which makes validation
and automatic processing a nightmare.

To make this easier, DPDK uses of a single line reference to
Unique License Identifiers in source files as defined by the Linux
Foundation's SPDX project https://spdk.org.

Adding license information in this fashion, rather than adding full license
text, can be more efficient for developers; decreases errors; and improves
automated detection of licenses. The current set of valid, predefined SPDX
identifiers is set forth on the SPDX License List at
https://spdx.org/licenses/.

For example, to label a file as subject to the BSD-3-Clause license,
the following text would be used as the top line of the file.

SPDX-License-Identifier: BSD-3-Clause

Note: Any new file contributions in DPDK shall adhere to the above scheme.
It is also recommended to replace or at least amend the existing license
text in the code with SPDX-License-Identifiers.

Any exception to DPDK IP policies shall be approved by DPDK tech board and
DPDK Governing Board. Steps for any exception approval:
1. Mention the appropriate license identifier form SPDX. If the license is
   not listed in SPDX Licenses. It is the submitters responsibiliity to get
   it first listed.
2. Get the required approval from the DPDK Technical Board. Technical board
   may advise the author to check alternate means first. If no other
   alternatives are found and the merit of the contributions are important
   for DPDK's mission, it may decide on such exception with two-thirds vote
   of the members.
3. Technical board then approach Governing board for such limited approval
   for the given contribution only.

Any approvals shall be documented in "licenses/exceptions.txt" with record
dates.

Note: From the legal point of view, this patch is supposed to be only a
change to the textual representation of the license information, but in no
way any change to the actual license terms. With this patch applied, all
files will still be licensed under the same terms they were before.

doc: update oldest supported kernel in Linux guide

The DPDK needs to stay up to date with current LTS Linux kernel support.
If the kernel is older than LTS it is likely to be insecure and buggy.
Therefore only require DPDK to work on oldest LTS kernel.

If distribution vendors want to support DPDK on older kernels, that is
their choice. But the upstream source does not need to be cluttered
with support for this.
