examples: detect default build directory

Most examples have in their makefiles a default RTE_TARGET directory to be
used in case RTE_TARGET is not set. Rather than just using a hard-coded
default, we can instead detect what the build directory is relative to
RTE_SDK directory.

This fixes a potential issue for anyone who continues to build using
"make install T=x86_64-native-linuxapp-gcc" and skips setting RTE_TARGET
explicitly, instead relying on the fact that they were building in a
directory which corresponded to the example default path - which was
changed to "x86_64-native-linux-gcc" by commit 218c4e68c1d9 ("mk: use
linux and freebsd in config names").

mk: use linux and freebsd in config names

Rather than using linuxapp and bsdapp everywhere, we can change things to
use the, more readable, terms "linux" and "freebsd" in our build configs.
Rather than renaming the configs we can just duplicate the existing ones
with the new names using symlinks, and use the new names exclusively
internally. ["make showconfigs" also only shows the new names to keep the
list short] The result is that backward compatibility is kept fully but any
new builds or development can be done using the newer names, i.e. both
"make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc"
work.

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: 8728ccf37615 ("fix ethdev ports enumeration")
Fixes: d9a42a69febf ("ethdev: deprecate port count function")

ethdev: deprecate port count function

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.

In order to fix this common mistake in all external applications,
the function rte_eth_dev_count is deprecated, while introducing
the new functions rte_eth_dev_count_avail and rte_eth_dev_count_total.
