5b9656b157 lib: build with meson
Add non-EAL libraries to DPDK build. The compat lib is a special case,
along with the previously-added EAL, but all other libs can be build using
the same set of commands, where the individual meson.build files only need
to specify their dependencies, source files, header files and ABI versions.

d35cc1fe6a eal/x86: revert select optimized memcpy at run-time
Revert the patchset run-time Linking support including the following
3 commits:

Fixes: 84cc318424 ("eal/x86: select optimized memcpy at run-time")
Fixes: c7fbc80fe6 ("test: select memcpy alignment unit at run-time")
Fixes: 5f180ae329 ("efd: move AVX2 lookup in its own compilation unit")

The patchset would cause perf drop in vhost/virtio loopback performance
test. Because the run-time dispatch must cost at least a function call
comparing to the compile-time dispatch. And the reference cpu cycles value
is small. And in the test, when using 128-256 bytes packet, it would cause
16%-20% perf drop with mergeble path. When using 256 bytes packet, it would
cause 13% perf drop with vector path.

cbc12b0a96 mk: do not generate LDLIBS from directory dependencies
The list of libraries in LDLIBS was generated from the DEPDIRS-xyz
variable. This is valid when the subdirectory name match the library
name, but it's not always the case, especially for PMDs.

The patches removes this feature and explicitly adds the proper
libraries in LDLIBS.

Some DEPDIRS-xyz variables become useless, remove them.

Compiler error:
irte_efd.o: In function `rte_efd_lookup':
rte_efd.c:(.text+0x6d6e): undefined reference to `efd_lookup_internal_avx2'
rte_efd.o: In function `rte_efd_lookup_bulk':
rte_efd.c:(.text+0x87d4): undefined reference to `efd_lookup_internal_avx2'

This can be observed with a compiler that doesn't support AVX2 and
shared build.

feb9f680cd mk: optimize directory dependencies
Before this patch, the management of dependencies between directories
had several issues:

- the generation of .depdirs, done at configuration is slow: it can take
  more than one minute on some slow targets (usually ~10s on a standard
  PC without -j).

- for instance, it is possible to express a dependency like:
  - app/foo depends on lib/librte_foo
  - and lib/librte_foo depends on app/bar
  But this won't work because the directories are traversed with a
  depth-first algorithm, so we have to choose between doing 'app' before
  or after 'lib'.

- the script depdirs-rule.sh is too complex.

- we cannot use "make -d" for debug, because the output of make is used for
  the generation of .depdirs.

This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.

After this commit, "make config" is almost immediate.

cb8fac62be efd: fix build by removing dependency to libmath
When we compile the dpdk with:
  CONFIG_RTE_LIBRTE_EFD=y
  CONFIG_RTE_LIBRTE_NFP_PMD=n
  CONFIG_RTE_LIBRTE_THUNDERX_NICVF_PMD=n
  CONFIG_RTE_LIBRTE_SCHED=n
  CONFIG_RTE_LIBRTE_METER=n

The linker gives the following error:
  lib/librte_efd.a(rte_efd.o): In function `rte_efd_create':
  lib/librte_efd/rte_efd.c:560: undefined reference to `log2'
  collect2: error: ld returned 1 exit status

This is because the '-lm' is missing in mk/rte.app.mk.

An alternative, which is proposed by this patch, is to use the compiler
builtin rte_bsf32() to process log2 instead of the libmath log2() that
requires to include math.h and link with -lm.

56b6ef874f efd: new Elastic Flow Distributor library
Elastic Flow Distributor (EFD) is a distributor library that uses
perfect hashing to determine a target/value for a given incoming flow key.
It has the following advantages:

- First, because it uses perfect hashing, it does not store
  the key itself and hence lookup performance is not dependent
  on the key size.

- Second, the target/value can be any arbitrary value hence
  the system designer and/or operator can better optimize service rates
  and inter-cluster network traffic locating.

- Third, since the storage requirement is much smaller than a hash-based
  flow table (i.e. better fit for CPU cache), EFD can scale to
  millions of flow keys.
  Finally, with current optimized library implementation performance
  is fully scalable with number of CPU cores.
