For commands that always output to stdout and don't have a "-o" or
"--output" or some other similar option, this 'capture' setting allows
the build to capture the result and place it in the output file.
D allows programmers to define their tests alongside the actual code in
a unittest scope[1].
When compiled with a special flag, the compiler will build a binary
containing the tests instead of the actual application.
This is a strightforward and easy way to run tests and works well with
Mesons test() command.
Since using just one flag name to enable unittest mode would be too
boring, compiler developers invented multiple ones.
Adding this helper method makes it easy for people writing Meson build
descriptions for D projects to enable unittestmode.

Because of how files and executables work on Windows, scripts that use
an interpreter must have an extension, and that extension must be
associated with an interpreter. The full list of executable extensions
is available in the PATHEXT environment variable.
However, UNIX-like OSes use an executable bit and read the shebang to
figure out what interpreter to use, and the scripts don't need to have
extensions. We can now detect these scripts using find_program by
manually searching in PATH and reading the shebang.
Target-specific compiler options should be split into pre-processor
defines, include directories, and additional options, then
escaped/quoted and added to the appropriate portions of the project
file.
The "115 spaces backslash" test now checks that backslashes and spaces
now work properly in all three places.
At the same time, this also adds a bunch of tests that document and keep
track of how we expect quoting to pass through via Ninja to the
compiler.
We need at least Ninja 1.6.0 for this.

After c01b183e5, the mtime of coredata.dat is always newer than all the
other build files, which made regen_checker think that they always had
to be regenerated. Now we set the mtime of the file to a value before
the build files are generated and that makes everything behave as it did
earlier.
This gives a clearer output when the dependency is not required or has a
fallback subproject otherwise the user is left wondering why the optional
dependency wasn't used or why the fallback subproject is being used.
