[PATCH v3 0/3] build contrib/plugins using meson

[Pierrick Bouvier <pierrick.bouvier@linaro.org>]

Contrib plugins have been built out of tree so far, thanks to a Makefile.
However, it is quite inconvenient for maintenance, as we may break them,
especially for specific architectures.

First patches are fixing warnings for existing plugins, then we add meson
support, and finally, we remove Makefile for contrib/plugins.

Based on the proposal of Anton Kochkov on associated gitlab issue.

Plugins are now deactivated by default on 32-bits hosts (since cf2a78), so we
can enable with meson without worrying of warnings when building plugins for 32
bits.

Removed patches for individual plugins.

v2:
- removed warnings fix for 32 bits as they were incorrect. They are not needed
  anymore as plugins are deprecated for 32 bits hosts.

v3:
- do not build lockstep on windows (it uses sys/socket.h)
- build new plugins recently added
- fix warning in cflow plugin
- tested it builds correctly on windows/macos/linux

Pierrick Bouvier (3):
  contrib/plugins/cflow: fix warning
  meson: build contrib/plugins with meson
  contrib/plugins: remove Makefile for contrib/plugins
