This fix issue when using --wipe and the machine file was passed as a
pipe and written locally, or when the file was resolved in XDG_DATA_HOME
or XDG_DATA_DIRS.
Fixes: #8560
This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
I would have prefered to do these seperatately, but they are combined in
some cases, so it was much easier to convert them together.
this eliminates the builtins_per_machine dict, as it's duplicated with
the OptionKey's machine parameter.
I wrote this to convert run_tests.get_backend_commands() over to the
new meson wrappers, but that turned out to be harder than I expected,
so just splitting this out for now.
When wiping a build tree with --wipe, every entry in the build directory
is removed with mesonlib.windows_proof_rmtree() for directories and
mesonlib.windows_proof_rm() for other files. Symlinks to directories are
considered directories, resulting in the former being called. This
causes an exception to be raised, as the implementation calls
shutil.rmtree(), which isn't allowed on symlinks.
Fix this by using mesonlib.windows_proof_rm() for symlinks.

Build and target info is confusing in that case. However still log that
information, as it is useful in case something slips out of sync and
needs to be debugged.
* coredata: Correctly handle receiving a pipe for native/cross files
In some cases a cross/native file may be a pipe, such as when using bash
process replacement `meson --native-file
<([binaries]llvm-config='/opt/bin/llvm-config')`, for example. In this
case we copy the contents of the pipe into a file in the meson-private
directory so we can create a proper ninja dependency, and be able to
reload the file on --wipe/--reconfigure. This requires some extra
negotiation to preserve these native/cross files.
Fixes#5505
* run_unitests: Add a unit test for native files that are pipes
Using mkfifo.
This creates a new command line option to store pkg_config_path into,
and store the environment variable into that option. Currently this
works like the environment variable, for both cross and native targets.
This seems to be related to deleting the current working directory.
Simply deleting all of the trees inside the build directory instead
seems to fix it. This only appears with some combination of generated
targets, running the test case against say "1 trivial" doesn't show the
bug.

It is similar to --reconfigure but completely wipe the build directory
first. It is intended to make easier to rebuild project when builddir somehow
got corrupted.
Fixes#3542.
Write command line options into a separate file to be able to
reconfigure from scatch in the case coredata cannot be loaded. The most
common case is when we are reconfiguring with a newer meson version.
This means that we should try as much as possible to maintain backward
compatibility for the cmd_line.txt file format.
The main difference with a normal reconfigure is it will use new
default options values and will read again environment variables like
CFLAGS, etc.
This has the adventage that "meson --help" shows a list of all commands,
making them discoverable. This also reduce the manual parsing of
arguments to the strict minimum needed for backward compatibility.
