This patch allows the same set of rte_metrics_tel_* functions to be
exported no matter JANSSON is available or not, by doing following:
1. Leverage dpdk_conf to set configuration flag RTE_HAS_JANSSON
when Jansson dependency is found.
2. In rte_metrics_telemetry.c, leverage RTE_HAS_JANSSON to handle the
case when JANSSON is not available by adding stubs for all the instances.
3. In meson.build, per dpdk/doc/guides/rel_notes/release_20_05.rst,
it is claimed that "Telemetry library is no longer dependent on the
external Jansson library, which allows Telemetry be enabled by default.",
thus make the deps and includes of Telemetry as not conditional anymore.

For using a DPDK application, such as OVS, which is dynamically linked, the
DPDK version in use should always report the actual version, not the
version used at build time. This incorrect behaviour can be seen by
building OVS against one version of DPDK and running it against a later
one. Using "ovs-vsctl list Open_vSwitch" to query basic info, the
dpdk_version returned will be the build version not the currently running
one - which can be verified using the DPDK telemetry library client.
$ sudo ovs-vsctl list Open_vSwitch | grep dpdk_version
dpdk_version : "DPDK 20.11.0-rc4"
$ echo quit | sudo dpdk-telemetry.py
Connecting to /var/run/dpdk/rte/dpdk_telemetry.v2
{"version": "DPDK 21.02.0-rc2", "pid": 405659, "max_output_len": 16384}
-->
To fix this, we need to convert the rte_version() function, and any other
necessary parts of the rte_version.h, to be actual functions in EAL, not
just inlines/macros. The only complication in doing so is that telemetry
library cannot call rte_version() directly, and instead needs the version
string passed in on init.

When checking the loading of EAL shared lib to see if we have a shared
DPDK build, we only want to include part of the ABI version in the check
rather than the whole thing. For example, with ABI version 21.1 for DPDK
release 21.02, the linker links the binary against librte_eal.so.21,
without the ".1".
To avoid any further brittleness in this area, we can check for multiple
versions when doing the check, since just about any version of EAL implies
a shared build. Therefore we check for presence of librte_eal.so with full
ABI_VERSION extension, and then repeatedly remove the end part of the
filename after the last dot, checking each time. For example (debug log
output for static build):
EAL: Checking presence of .so 'librte_eal.so.21.1'
EAL: Checking presence of .so 'librte_eal.so.21'
EAL: Checking presence of .so 'librte_eal.so'

To verify that all DPDK headers are ok for inclusion directly in a C file,
and are not missing any other pre-requisite headers, we can auto-generate
for each header an empty C file that includes that header. Compiling these
files will throw errors if any header has unmet dependencies.
For some libraries, there may be some header files which are not for direct
inclusion, but rather are to be included via other header files. To allow
later checking of these files for missing includes, we separate out the
indirect include files from the direct ones.

Add a simple on/off switch that will enable saving power when no
packets are arriving. It is based on counting the number of empty
polls and, when the number reaches a certain threshold, entering an
architecture-defined optimized power state that will either wait
until a TSC timestamp expires, or when packets arrive.
This API mandates a core-to-single-queue mapping (that is, multiple
queued per device are supported, but they have to be polled on different
cores).
This design is using PMD RX callbacks.
1. UMWAIT/UMONITOR:
When a certain threshold of empty polls is reached, the core will go
into a power optimized sleep while waiting on an address of next RX
descriptor to be written to.
2. TPAUSE/Pause instruction
This method uses the pause (or TPAUSE, if available) instruction to
avoid busy polling.
