[1/3] build: enable a developer mode setting
Checks
Commit Message
To allow support for additional build checks and tests only really
relevant for developers, we add support for a developer mode option to
DPDK. The default, "auto", value for this enables developer mode if a
".git" folder is found at the root of the source tree - as was the case
with the previous "make" build system. There is also support for
explicitly enabling or disabling this option using "meson configure" if
so desired.

DPDK is built using the tools ``meson`` and ``ninja``.

+ In order to catch possible issues as soon as possible,
+ it is recommended that developers build DPDK in "developer mode" to enable additional checks.
+ By default, this mode is enabled if the build is being done from a git checkout,
+ but the mode can be manually enabled/disabled using the
+ ``developer_mode`` meson configuration option.

Therefore all new component additions should include a ``meson.build`` file,
and should be added to the component lists in the ``meson.build`` files in the
relevant top-level directory:
