The GIR files are now built by GLib itself, so they will be in the build
directories of each sub-library, except for GLib-2.0 which is built
alongside GObject-2.0.
All the calls to `usage()` are immediately followed by a `return` from
`main()` which sets an appropriate exit status.
Calling `exit()` early means that running `gio --help` returns exit
status 1, which is incorrect — it should (by convention) return 0.

If the string of one log domain is contained in
another, it was printing both.
For example, if G_MESSAGES_DEBUG is "Gtkspecial",
it would also keep the logs of the "Gtk" domain
Depending on the operating system, /bin/sh might either be bash (for
example on Fedora or Arch) or dash (for example on Debian or Ubuntu)
or some other POSIX shell.
When bash is asked to run a simple command with no shell keywords or
metacharacters, like this one, it replaces itself with the program
via execve(), but dash does not have that optimization and treats it
like any other program invocation in a larger script: it will fork,
exec the program in the child, and wait for the child in the parent.
This seems like it conflicts with sleep_and_kill() assuming that it can
use the subprocess's process ID as the sleep(1) process ID. Specifically,
if it sends SIGKILL, it will go to the sh(1) process and not the sleep(1)
child, which could result in the sh(1) process being terminated and
its sleep(1) child being leaked.
To get the bash-like behaviour portably, explicitly use the exec builtin
to instruct the shell to replace itself with sleep(1), so that the
process ID previously used for the shell becomes the process ID of the
sleep process.
This appears to resolve an intermittent hang and test timeout on Debian
machines (especially slower ones), although I'm not 100% clear on the
mechanics of how it happens.

The weak symbol resolution doesn’t seem to work (see

```

`test-generated.txt` is listed in `test.gresource.xml`, so it needs to
be specified as a dependency in the `custom_target()` which uses
`test.gresource.xml`.
Fixes intermittent build failures like:
```
FAILED: gio/tests/test.gresource

This reverts commit 0b9900e4e7.
The dependency was added in the wrong place: `test-generated.txt` is
needed when compiling `test.gresource`, not when compiling the test
which ultimately uses that gresource.
See !3671 and #3163.
GLib ignores various leaks that we don't consider as such (like the
default gio modules) via the LSAN public interface, however those cases
are always ignored when using a non-ASAN compiled glib is used by an
ASAN-compiled binary.
This makes all the GLib-related programs to fail because of false
positive leaks.
To avoid this, use the gcc extension for weak linking so that we can
control ASAN and LSAN only if the symbols they provide are actually
available at runtime.
The PTRACE_O_EXITKILL symbol in sys/ptrace.h is an enum member, not
a macro. The #ifdef check added to the GSubprocess test-case in
272ec5dbca will not detect it.
Use cc.has_header_symbol() to properly detect it. According to the
documentation: "Symbols here include function, variable, #define,
type definition, etc.".

Make sure that each C file in `girepository/` includes its corresponding
header file (if such a file exists).
This ensures that the first declaration the compiler sees for each
function contains the symbol visibility macros. This fixes symbol export
(`dllexport`) on Windows platforms.

`gthash.c` transitively includes it.
Most of this commit is just moving variables around so `gi_visibility_h`
is defined early enough in the file. The moved code has not been changed.

These are all custom-written, including a load of research in `git log`
to find the copyright holders for `girepository/meson.build` and
`girepository/gi-dump-types.c`.
With this, `reuse lint` raises no complaints about the `girepository/`
directory.
