rte_eal_memory_detach() did not account for cases where multi-process
mode is disabled: --in-memory and --no-shconf. This resulted
in unmapping memory that had not been mapped, which caused errors:
EAL: Could not unmap memory: No error (Windows)
EAL: Cannot munmap(0x1d47f40, 0x7000): Invalid argument (Linux)
Confusing "No error" was caused by using errno instead of rte_errno
set by rte_mem_unmap().

Note: such definitions are unneeded in eal_common_errno.c.
Applications which do not define _GNU_SOURCE may miss cpu_set_t related

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.
