When a dependency is required, not found on the system, and its fallback
is disabled with --wrap-mode=nofallback, meson should abort instead of
returning not-found.
declare_dependencies
This allows dependencies declared in subprojects to set variables, and
for those variables to be accessed via the get_variable method, just
like those from pkg-config and cmake. This makes it easier to use
projects from subprojects in a polymorphic manner, lowering the
distinction between a subproject and an external dependency every
further.
this can be useful for if/elif where linker behaviors must be
considered.
For example, clang with "link" vs gcc with "ld.bfd" etc.

Refactor the code inside a common function for consistency.
It's not needed to add dependencies in func_configure_file() because
it's already done in run_command_impl(). Do it only for files from
`input:` in the case some of them does not end up in the command
arguments.
* Have set() and set_quoted() of configuration object work with newlines.
set_quoted() makes the value into a double-quoted string, so let's
assume C-style string, in particular with newlines as "\n".
Also take care of remaining newlines in dump_conf_header(). C or nasm
macros expect single-line values so if the value was multi-line, we
would end up with broken syntax. Appending a backslash at each end of
line make them concat into a single line in both C and nasm format
(note: multi-line macros in nasm are actually possible apparently but
use another format not outputted by current meson code). Also note that
the replacement is done at the end only when dumping the conf as a
header because we cannot assume anything about the format when replacing
variables from an input file (in this case, it should be the dev
responsibility).
* Add unit tests for multiline set() and set_quoted().
Instead of only displaying the identifier of the linker, display also the path
to the executable in order to report useful information when cross-compiling.
In a large project, it can be hard to guess what meson "had in mind", when many different
warnings are added in different places. Let's make the message precise and specify the location.
WARNING: Consider using the built-in warning_level option instead of adding warning flags by hand.

The idea is that end-users want to specify an array of directories to search by default
without an if/elif stack. It's obvious that Unix absolute paths are not absolute on
Windows, so silently discard Unix absolute paths here for Windows instead of raising
exception.
This fixes two separate issues, one is that benchmark warns about
depends and priority; The other is that we passed bad values like
is_parallel into the test and would actually run benchmarks in parallel,
which is bad.
In qemu, minikconf generates a depfile that meson could use to
automatically reconfigure on dependency change.
Note: someone clever can perhaps find a way to express this with a
ninja rule & depfile=. I didn't manage, so I wrote a simple depfile
parser.
Since commit 38a658214 ("configure_file: Support taking values from a
dict" #4236), configuration_data() and configure_file()'s
configuration kwarg can take a dict. Add missing version checks.
