If the overlay's target is only created in a previous fragment, it
doesn't exist in the unmodified base device tree. For the phandle
overwrite check this can be ignored because in this case the base tree
doesn't contain a phandle that could be overwritten.
Adapt the corresponding check to not error out if that happens but just
continue with the next fragment.
This is currently triggered by
arch/arm64/boot/dts/renesas/salvator-panel-aa104xd12.dtso in the kernel
repository which creates /panel in its first fragment and modifies it in
its second.

The meson-python backend fails to map 'dtdiff' install into Python
wheels. Removing the prefix from the install_dir path allows
meson-python to map dtdiff. The install_data(install_dir) documentation
says "If this is a relative path, it is assumed to be relative to the
prefix"[1]. So removing the prefix does not change the installation
behaviour.

Meaning the python library is getting recompiled during the `meson
install` phase. This causes build issues as Meson does not set the
compiler and linker flags during the install phase.
The reason the library is getting rebuilt is during the normal build
with "build_ext", the `--build-lib` flag gets passed which changes the
default output build directory. But there is no equivalent option for
the "install" command. Install instead looks in the default directory
"./build" and so does not find the previously built library.
Since we can't fix the "install" command, drop the --build-lib flag.
This causes setup.py to compile the libraries at
`<meson-build>/build/lib.linux-x86_64-cpython-312/`. We must also then
fix run_tests.sh to find the library build directory as it's
machine-dependent.

It appears this is because the PyTuple_GET_SIZE() function that was used
to build the fdt_get_mem_rsv() return value has changed. It now is
returning a non-zero value when it's passed an integer, which causes the
SWIG wrapper to append the returned arguments to the return error rather
then ignore them.
This is valid behaviour per Python's documentation, which says it will
"Return the size of the tuple p, which must be non-NULL and point to a
tuple; no error checking is performed"[1]. As passing an integer is not
a tuple, its return value is undefined.
Fix this issue on older and newer versions by avoiding
PyTuple_GET_SIZE() entirely. Always append the arguments to the list,
and instead use the wrapper python function to check the first argument
and then splice the last two arguments as the return value.

On systems that do not use the FHS, such as NixOS, the `install` program is not
located in `/usr/bin/` as its location is dynamic.
`dtc` can be easily installed on such systems by using the `install` program
available in the `$PATH` with:
make PREFIX=… INSTALL=install
However, this becomes more difficult when `dtc` is being compiled as part of a
larger toolchain, as the toolchain build scripts will not spontaneously pass
such an argument on the command line. This happens for example when `dtc` is
build as a part of the RTEMS build system.
By not hardcoding a predefined path for `install`, as is done for other
executables, `dtc` will allow the one in the `$PATH` to be used.

When the DTS output has no type markers, we have to guess the type. Prior
to commit 32b9c61307 ("Preserve datatype markers when emitting dts
format"), instances of string lists would be delimited. Since then, a
single string with embedded "\0"s are emitted. An embedded "\0" is valid
for DTS files, but that's a rare exception and lists of strings are the
overwhelming majority. Restore the prior behavior.
stringlist.dts is reused for testing this, but needs a couple of tweaks
in order to match the dts output.

According to the documentation, the function should default to the very
common property name <reg> when none is "specified". However, neither
passing NULL (ends up calling strlen(NULL) and segfaults) nor ""
(appends a property with an empty name) implements this behavior.
Furthermore, the test case supposed to cover this default value actually
passes the value to the function, somewhat defeating its own purpose:
/* 2. default property name */
// ...
err = fdt_appendprop_addrrange(fdt, 0, offset, "reg", addr, size);
if (err)
FAIL("Failed to set \"reg\": %s", fdt_strerror(err));
check_getprop_addrrange(fdt, 0, offset, "reg", 1);
Finally, nothing in the implementation of the function seems to attempt
to cover that use-case.
As the feature can't ever have been used by clients and as the resulting
reduced readability of the caller seems (IMO) to outweigh any potential
benefit this API would bring, remove the erroneous documentation instead
of trying to fix the function.
