This was broken because the class property will say True but the
object property will not be set. Store the value on the class property
and transfer to object in __init__. Just like PkgConfigDependency.
While adding link args for external deps, sometimes different
libraries come from different prefixes, and an older version of the
same library might be present in other prefixes and we don't want to
accidentally pick that up.
For example:
/usr/local/lib/libglib-2.0.so
/usr/local/lib/pkgconfig/glib-2.0.pc
/usr/local/lib/libz.so
/usr/local/lib/pkgconfig/zlib.pc
/home/mesonuser/.local/lib/libglib-2.0.so
/home/mesonuser/.local/lib/pkgconfig/glib-2.0.pc
PKG_CONFIG_PATH="/home/mesonuser/.local/lib/pkgconfig/:/usr/local/lib/pkgconfig/"
If a target uses `dependencies : [glib_dep, zlib_dep]`, it will end up
using /usr/local/lib/libglib-2.0.so instead of
/home/mesonuser/.local/lib/libglib-2.0.so despite using the pkg-config
file in /home/mesonuser/.local/lib/pkgconfig because we reorder the -L
flag and separate it from the -l flag.
With this change, external link arguments will be added to the
compiler list without de-dup or reordering.

While g-ir-scanner's compatible -I and -D flags cover what most dependencies
use, there's no guarantee that a dependency's cflags don't include more
exotic flags that conflict with the tool's own options.
For a real world example, mozjs-38 has '-include some-header-file.h', which
translates to '--include nclude another-file-to-scan.h' for the scanner;
unless for some reason there's an 'nclude' GIR available on the system,
the target will thus fail.
For this purpose, g-ir-scanner allows explicitly marking some flags as
preprocessor/compiler flags by guarding them with --cflags-begin and
--cflags-end. Make sure it is used this for all cflags, not only for
global and project flags.
Boost tests are disabled on Windows for now because the detection
is actually completely broken. Once that's fixed (after the release)
we can enable it again.
- Adds a `crate_type` kwarg to library targets, allowing the different
types of Rust [linkage][1].
- Shared libraries use the `dylib` crate type by default, but can also
be `cdylib`
- Static libraries use the `rlib` crate type by default, but can also
be `staticlib`
- If any Rust target has shared library dependencies, add the
appropriate linker arguments, including rpath for the sysroot of the
Rust compiler
