Meson calls `path/to/clang++ --version` to guess which build toolchain the
user has picked to build the source code. For the Qualcomm LLVM toolchain,
the output have an unusual output as shown below:
```
clang version 8.0.12
Snapdragon LLVM ARM Compiler 8.0.12 (based on llvm.org 7.0+)
Target: arm-unknown-linux-gnueabi
Thread model: posix
Repository: (ssh://git-hexagon-aus.qualcomm.com:...)
InstalledDir: /pkg/qct/software/llvm/release/arm/8.0.12/bin
```
Another unusual pattern is the output of `path/to/ld.qcld --version`:
```
ARM Linker from Snapdragon LLVM ARM Compiler Version 8.0.12
ARM Linker based on LLVM version: 8.0
```
The Meson logic is modified accordingly so that Meson can correctly
determine toolchain as "LLVM aarch64 cross-compiler on GNU/Linux64 OS".
This is the expected output of
`meson --native-file native_file.ini --cross-file cross_file.ini build/aarch64-debug/`:
```
...
C++ compiler for the host machine: ... (clang 8.0.12 "clang version 8.0.12")
C++ linker for the host machine: ... ld.lld 8.0.12
...
```
This creates a full set of option in environment that mirror those in
coredata, this mirroring of the coredata structure is convenient because
lookups int env (such as when initializing compilers) becomes a straight
dict lookup, with no list iteration. It also means that all of the
command line and machine files are read and stored in the correct order
before they're ever accessed, simplifying the logic of using them.
This puts all of them together, in the next patch they'll be pulled back
out, but it's convenient to start that refactor by moving them all
there, then moving them into env as a whole.
This attempts to clarify the usage of strings and arrays, as well as
document the boolean type that has been exposed via the project and
built-in options
This is like the project options, but for meson builtin options.
The only real differences here have to do with the differences between
meson builtin options and project options. Some meson options can be set
on a per-machine basis (build.pkg_config_path vs pkg_config_path) others
can be set on a per-subproject basis, but should inherit the parent
setting.
This allows adding a `[project options]` section to a cross or native file
that contains the options defined for a project in it's meson_option.txt
file.
Since -Wl,-rpath= is not the only valid rpath ldflags syntax we
need to try and match all valid rpath ldflags.
In addition we should prevent -Wl,--just-symbols from being used to
set rpath due to inconsistent compiler support.

Fixup for b4b1a2c5a1.
A warning would be printed for any rule with multiple outputs, for
example:
WARNING: custom_target 'coredump.conf.5' has more than one output! Using the first one.
WARNING: custom_target 'dnssec-trust-anchors.d.5' has more than one output! Using the first one.
WARNING: custom_target 'halt.8' has more than one output! Using the first one.
Fixes https://github.com/systemd/systemd/issues/16461.
'native:' keyword was only added in 0.54. For projects declaring
meson_version >= 0.54, warn, because those projects can and should set
the keyword. For older projects declaring support for older versions,
don't warn and use the default implicitly.
Fixes https://github.com/mesonbuild/meson/issues/6849.
otherwise we are getting errors like:

This extends the 109 generatecode test case to also define a test, so
coverage can really detect something.
* Add boost_root support to properties files
This commit implements `boost_root`, `boost_includedir`, and
`boost_librarydir` variable support to native and cross properties
files. The search order is currently environment variables, then
these variables, and finally a platform-dependent search.
* Add preliminary boost_root / boost_includedir tests
Each test contains a fake "version.hpp", as that's how boost detection is
currently being done. We look for this file relative to the root directory,
which probably shouldn't be allowed (it previously was for BOOST_LIBRARYDIR
but not for BOOST_ROOT). It also cannot help with breakage detection in
libraries, however it looks like this wasn't getting tested beforehand.
I've given the two unique version numbers that shouldn't be present in any
stock version of boost (001 and 002).
* Add return type to detect_split_root
* Return empty list when nothing found in BOOST_ROOT, rather than None
* Update boost_root tests
* Create nativefile.ini based on location of run_project_tests.py
* Add fake libraries to ensure boost_librarydir is being used
* Require all search paths for boost to be absolute
* Redo boost search ordering
To better match things like pkg-config, we now look through native/cross files,
then environment variables, then system locations for boost installations.
Path detection does not fall back from one method to the next for properties or
environment variables--if boost_root, boost_librarydir, or boost_includedir is
specified, they must be sufficient to find boost. Likewise for BOOST_ROOT and
friends. pkg-config detection is still optional falling back to system-wide
detection, for Conan.
(Also, fix a typo in test 33's nativefile)
* Correct return type for detect_roots
* Correct boost dependency search order in documentation
* Print debug information for boost library finding, to resolve CI issues
* Handle native/cross file templates in a more consistent way
All tests can now create a `nativefile.ini.in` if they need to use some
parameter that the testing framework knows about but they can't.
* Pass str--rather than PosixPath--to os.path.exists, for Python35
* Look for boost minor versions, rather than boost patch versions in test cases
* Drop fake dylib versions of boost_regex
* Prefer get_env_var to use of os.environ
* Correct error reporting for relative BOOST_ROOT paths
* Bump version this appears in. Also, change "properties file" to "machine file" as that appears to be the more common language.
We have experimented with the module for about a year in a qemu
branch (https://wiki.qemu.org/Features/Meson), and we would like to
start moving the build system to meson. For that, keyval should have
the stability guarantees.
