eal: factorize lcore main loop
All OS implementations provide the same main loop.
Introduce helpers (shared for Linux and FreeBSD) to handle synchronisation
between main and threads and factorize the rest as common code.
Thread id are now logged as string in a common format across OS.
Note:
- this change also fixes Windows EAL: worker threads cpu affinity was
incorrectly reported in log.
- libabigail flags this change as breaking ABI in clang builds:
1 function with some indirect sub-type change:
[C] 'function int rte_eal_remote_launch(int (void*)*, void*, unsigned
int)' at eal_common_launch.c:35:1 has some indirect sub-type
changes:
parameter 1 of type 'int (void*)*' changed:
in pointed to type 'function type int (void*)' at rte_launch.h:31:1:
entity changed from 'function type int (void*)' to 'typedef
lcore_function_t' at rte_launch.h:31:1
type size hasn't changed
This is being investigated on libabigail side.
For now, we don't have much choice but to waive reports on this symbol.

support systemd service convention for runtime directory
Systemd.exec supports configuring the runtime directory of a service
via RuntimeDirectory=. This creates the directory with the necessary
permissions which actual service may not have if running in container.
The change to DPDK is to look for the environment RUNTIME_DIRECTORY
first and use that in preference to the fallback alternatives.

eal/linux: allow hugepage file reuse
Linux EAL ensured that mapped hugepages are clean
by always mapping from newly created files:
existing hugepage backing files were always removed.
In this case, the kernel clears the page to prevent data leaks,
because the mapped memory may contain leftover data
from the previous process that was using this memory.
Clearing takes the bulk of the time spent in mmap(2),
increasing EAL initialization time.
Introduce a mode to keep existing files and reuse them
in order to speed up initial memory allocation in EAL.
Hugepages mapped from such files may contain data
left by the previous process that used this memory,
so RTE_MEMSEG_FLAG_DIRTY is set for their segments.
If multiple hugepages are mapped from the same file:
1. When fallocate(2) is used, all memory mapped from this file
is considered dirty, because it is unknown
which parts of the file are holes.
2. When ftruncate(3) is used, memory mapped from this file
is considered dirty unless the file is extended
to create a new mapping, which implies clean memory.
