Thanks to `ModuleInfo`, all modules are just named `foo.py` instead of
`unstable_foo.py`, which simplifies the import method a bit. This also
allows for accurate FeatureNew/FeatureDeprecated use, as we know when
the module was added and if/when it was stabilized.
We have experimented with the module for about a year in a qemu
branch (https://wiki.qemu.org/Features/Meson), and we would like to
start moving the build system to meson. For that, keyval should have
the stability guarantees.

D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
Discussions in #6524 have shown that there are various possible uses of the
kconfig module and even disagreements in the exact file format between
Python-based kconfiglib and the tools in Linux. Instead of trying to
reconcile them, just rename the module to something less suggestive and
leave any policy to meson.build files.
In the future it may be possible to add some kind of parsing through
keyword arguments such as bool_true, quoted_strings, etc. and possibly
creation of key-value lists too. For now, configuration_data objects
provide an easy way to access quoted strings. Note that Kconfig stores
false as "absent" so it was already necessary to write "x.has_key('abc')"
rather than the more compact "x['abc']". Therefore, having to use
configuration_data does not make things much more verbose.
