fa47405cc1 ethdev: remove experimental flag of ports enumeration
The basic operations for ports enumeration should not be
considered as experimental in DPDK 18.05.

The iterator RTE_ETH_FOREACH_DEV was introduced in DPDK 17.05.
It uses the function the rte_eth_find_next_owned_by() to get
only ownerless ports. Its API can be considered stable.
So the flag experimental is removed from rte_eth_find_next_owned_by().

The flag experimental is removed from rte_eth_dev_count_avail()
which is the new name of the old function rte_eth_dev_count().

The flag experimental is set to rte_eth_dev_count_total()
in the .c file for consistency with the declaration in the .h file.

A lot of internal applications are fixed to not allow experimental API.

Fixes: d9a42a69febf ("ethdev: deprecate port count function")

8728ccf376 fix ethdev ports enumeration
Some DPDK applications wrongly assume these requirements:
    - no hotplug, i.e. ports are never detached
    - all allocated ports are available to the application

Such application iterates over ports by its own mean.
The most common pattern is to request the port count and
assume ports with index in the range [0..count[ can be used.

There are three consequences when using such wrong design:
    - new ports having an index higher than the port count won't be seen
    - old ports being detached (RTE_ETH_DEV_UNUSED) can be seen as ghosts
    - failsafe sub-devices (RTE_ETH_DEV_DEFERRED) will be seen by the application

Such mistake will be less common with growing hotplug awareness.
All applications and examples inside this repository - except testpmd -
must be fixed to use the iterator RTE_ETH_FOREACH_DEV.

1842d194c9 examples: enable linking both static and shared
Since the DPDK build now includes both static and shared libraries, we need
a new way to enable building the examples using either method from the one
installation. To do this, we add in a default "shared" target, and a
separate "static" target which links in the DPDK static libraries. In both
cases, the final application name is symlinked to the last-built static or
shared target, with both binaries able to co-exist in the build directory.

22119c4591 examples: use pkg-config in makefiles
Change the example app Makefiles to query if DPDK is installed and
registered using pkg-config. If so, build directly using pkg-config info,
otherwise fall back to using the original build system with RTE_SDK and
RTE_TARGET

This commit changes the makefiles for the basic examples, i.e. those which
do not have multiple subdirectories underneath the main examples dir.
Examples not covered are:

* ethtool
* multi_process
* performance-thread
* quota_watermark
* netmap_compat
* server_node_efd
* vm_power_manager

0eba4ade65 examples: put app name and sources at top of makefiles
Reorder the text in the makefiles, so that the app name and the source
files are listed first. This then will allow them to be shared later in a
combined makefile building with pkg-config and RTE_SDK-based build system.
