Way back in Meson 0.25, support was added to `vala_args` for Files.
Strangely, this was never added to any other language, though it's been
discussed before. For type safety, it makes more sense to handle this in
the interpreter level, and pass only strings into the build IR.
This is accomplished by adding a `depend_files` field to the
`BuildTarget` class (which is not exposed to the user), and adding the
depend files into that field, while converting the arguments to relative
string paths. This ensures both the proper build dependencies happen, as
well as that the arguments are always strings.
This allows changing the crate name with which a library ends up being
available inside the Rust code, similar to cargo's dependency renaming
feature or `extern crate foo as bar` inside Rust code.
Generated objects can already be passed in the "objects" keyword argument
as long as you go through an extract_objects() indirection. Allow the
same even directly, since that is more intuitive than having to add them
to "sources".

The documentation for build_target(...) does not list file or str as
the possible types for the "objects" keyword argument, even though in
theory the argument is meant for prebuild object files that are part
of the sources.
Of course that is only the theory, because an ExtractedObjects object
is probably used a lot more than a file in the source tree. But
at least make the reference manual's typing information accurate.
This is based on searching for `@FeatureNew*` decorators.
There is also one correction to a version in a decorators;
`build_by_default` was added in #1303, which is 0.38.0, not 0.40.0.
Dlang uses both integer version "levels" and arbitrary string
identifiers, and we support both, but don't mention it in the docs.
Also update a test case to pass one via declare_dependency. We already
test this kwarg for build_target.
In the original RefMan 2.0 implementation, the types for this were
filled in as `str | file`, but the code only ever accepted the former.
Fix the documentation so that it aligns with reality.
Fixes#10338
This bring us in line with Autotools and CMake and it is useful
for platforms like Nix, which install projects
into multiple independent prefixes.
As a consequence, `get_option` might return absolute paths for some
directory options, if a directory outside of prefix is passed.
This is technically a backwards incompatible change but its effect
should be minimal, thanks to widespread use of `join_paths`/`/` operator
and pkg-config generator module. It should only cause an issue when
a path were constructed by concatenating the value of directory path option.
Also remove a comment about commonpath since we do not use that since
<00f5dadd5b>.
