examples: skip build when missing dependencies

Trying to disable the vhost library, meson will complain it can't build
the vhost* and vdpa examples when passing -Dexamples=all.

-Dexamples=all skips examples if the example itself announces it can't
be built (for external dependencies, internal dependencies and other
reasons).
Since examples/meson.build will evaluate the internal dependencies
in any case, let's move the check there and resolve the issue for
optional internal libraries.

build: detect execinfo library on Linux

The library execinfo and its header file can be installed on Alpine Linux
where the backtrace feature is not part of musl libc:
apk add libexecinfo-dev

As a consequence, this library should not be restricted to BSD only.

At the same time, the library and header are detected once and added
globally to be linked with any application, internal or external.

build: exclude meson files from examples installation

The meson.build files in each example directory is simply to support
building the example as part of the main SDK build, and these should not
be installed with the example's source code and makefile. The exclude of
"meson.build" only filters out the top-level examples/meson.build file,
not the file in each subdirectory.

To fix this, we can build up the list of files to exclude based off the
list of all examples. With this change "find examples/ -name meson.build"
returns no hits when run on an installed instance.

When dpdk is compiled as static libraries, it is not possible
to load a plugin from an application. We get the following error:

EAL: librte_pmd_xxxx.so: undefined symbol: per_lcore__rte_errno

This happens because the dpdk symbols are not exported. Add them to the
dynamic symbol table by using '-Wl,--export-dynamic'. This option was
previously present when compiled with Makefiles, it was introduced in
commit f9a08f650211 ("eal: add support for shared object drivers")

Also add it to the pkg-config file.

By installing the examples one-by-one in a loop in the examples

folder and omitted some common and shared subfolders that were never
directly built. Instead, we can remove the loop and just have the whole
"examples" folder installed as-is in a single statement, preserving its
directory structure, and thereby fixing the build of a number of the
examples.

examples/tep_term: remove this application

This example sets up a scenario that VXLAN packets can be received
by different PF queues based on VNID and each queue is bound to a VM
with a VNID so that the VM can receive its inner packets.

Usually, OVS is used to do the software encap/decap for VXLAN packets.

And the VXLAN packets offloading can be replaced with flow rules in
testpmd like Chapter "Sample VXLAN flow rules" in Testpmd Application
User Guide.

And this example hasn't been used for a long time.

So deprecate this example.

build: always link whole DPDK static libraries

To ensure all constructors are included in static build, we need to pass
the --whole-archive flag when linking, which is used with the
"link_whole" meson option. Since we use link_whole for all libs, we no
longer need to track the lib as part of the static dependency, just the
path to the headers for compiling.

After this patch is applied, all DPDK .a files are inside
--whole-archive/--no-whole-archive flags, but external dependencies and
shared libs being linked against remain outside.
