It's possible that the configuration data object has components added
conditionally, and that sometimes an empty configuration data object
is passed on purpose.
Instead, we do the substitution and also warn if no tokens were found
that could've been substituted.

We now pass the current subproject to every FeatureNew and
FeatureDeprecated call. This requires a bunch of rework to:
1. Ensure that we have access to the subproject in the list of
arguments when used as a decorator (see _get_callee_args).
2. Pass the subproject to .use() when it's called manually.
3. We also can't do feature checks for new features in
meson_options.txt because that's parsed before we know the
meson_version from project()
* Use _get_callee_args to unwrap function call arguments, needed for
module functions.
* Move some FeatureNewKwargs from build.py to interpreter.py
* Print a summary for featurenew only if conflicts were found. The
summary now only prints conflicting features.
* Report and store featurenew/featuredeprecated only once
* Fix version comparison: use le/ge and resize arrays to not fail on
'0.47.0>=0.47'

A number of cases have to be taken care of while doing this, so
refactor it into a helper on ExternalProgram and use it everywhere.
1. Command is a list of len > 1, use it as-is
2. Command is a list of len == 1 (or a string), use as a string
3. If command is an absolute path, use it as-is
4. If command is not an absolute path, search for it
This is accepted by all other binaries in the cross file. With this
change, we also don't check whether the specified command exists at
configure time, but that's probably a feature anyway.

D is not a 'c-like' language, but it can link to C libraries. The same
might be true of Rust in the future and Go when we add support for it.
This contains no functionality changes.
Make a custom target output dir as an include dir relative to @BUILD_ROOT@,
so that path is constructed correctly when using the absolute path forms
used by the MSVC backend.
Since `build_always` also adds a target to the set of default targets,
this option is marked deprecated in favour of the new option
`build_always_stale`.
`build_always_stale` *only* marks the target to be always considered out
of date, but does *not* add it to the set of default targets.
The old behaviour can still be achieved by combining
`build_always_stale` with `build_by_default`.

This is a special type of option to be passed to most 'required' keyword
arguments. It adds a 3rd state to the traditional boolean value to cause
those methods to always return not-found even if the dependency could be
found.
Since integrators doesn't want enabled features to be a surprise there
is a global option "auto_features" to enable or disable all
automatic features.
Added method concatenate_string_literals to CCompiler. Will concatenate
string literals.
Added keyword argument 'concatenate_string_literals' to Compiler.get_define.
If used will apply concatenate_string_literals to its return value.
Input files can be in any file encoding, not just utf-8 or isolatin1. Meson
should not make assumptions here and allow for the user to specify the
encoding to use.
This simplifies a lot of code, and centralize "key=value" parsing in a
single place.
Unknown command line options becomes an hard error instead of
merely printing warning message. It has been warning it would become an
hard error for a while now. This has exceptions though, any
unknown option starting with "<lang>_" or "b_" are ignored because they
depend on which languages gets added and which compiler gets selected.
Also any option for unknown subproject are ignored because they depend
on which subproject actually gets built.
Also write more command line parsing tests. "19 bad command line
options" is removed because bad cmd line option became hard error and
it's covered with new tests in "30 command line".
All options are now the projectoptions list, regardless of how they got
defined in the command line.
This also delays setting builtin option values until the main project()
default options are parsed to simplify the code. This is possible
because we already delayed setting the backend after parsing main
project() in a previous commit.
The project() function could have a different value for the backend
option in its default_options kwargs.
Also set backend options, passing them in command line had no effect
previously.
This makes it possible to customize permissions of all installable
targets, such as executable(), libraries, man pages, header files and
custom or generated targets.
This is useful, for instance, to install setuid/setgid binaries, which
was hard to accomplish without access to this attribute.
