These scripts use $(readlink -f) to guess their own path if necessary,
but macOS readlink doesn't support the -f option, and POSIX doesn't
guarantee that readlink even exists.

The `gi-docgen` tool is not designed to be used like that. In
particular, when nesting documentation directories, the generated
`*.devhelp2` files (needed by Devhelp to show the documentation) are
nested one directory level too deep for Devhelp to find them, and hence
are useless, and the documentation doesn’t show up in this common
documentation viewer.
So, change the installed documentation directory hierarchy:
* `${PREFIX}/share/doc/glib-2.0/gio` → `${PREFIX}/share/doc/gio-2.0`
* `${PREFIX}/share/doc/glib-2.0/glib-unix` →
`${PREFIX}/share/doc/glib-unix-2.0`
* `${PREFIX}/share/doc/glib-2.0/gobject` →
`${PREFIX}/share/doc/gobject-2.0`
* etc.
* `${PREFIX}/share/doc/glib-2.0/glib` → `${PREFIX}/share/doc/glib-2.0`
This is going to seem like pointless churn (the contents of the
documentation have not changed), and packagers may mourn the split of
content in `/usr/share/doc` from `/usr/share/doc/${package_name}` to
`/usr/share/doc/${pkg_config_id}` instead, but that seems to be the best
approach to fix this issue in GLib. gi-docgen’s behaviour does feel
fairly consistent and correct with the rest of how it works (single
output directory).

These unfortunately have `gchar*` return types rather than `const
gchar*`. This is a historical artifact which we can’t change: while
adding `const` would only be an API break and not an ABI break, it would
cause all sorts of C++ code which uses GLib to emit new cast warnings
(similarly, C code with const correctness compiler warnings enabled
would do the same).
The incorrect return type causes the GIR scanner to (reasonably) assume
the return value is allocated, which is wrong.
Fix that by explicitly adding `(transfer none)`.
Also add an explicit `(nullable)` because all three functions are.

The gdbus-example-objectmanager visibility header was being re-created
on reconfigure, causing a needless rebuild of gdbus tests that were
using the visibility header.
All other invocations of gen_visibility_macros are via custom_target.
The documentation previously implied that they could. That’s not really
true though: they can only fail if preconditions fail, i.e. they’re
passed invalid input. That’s a programmer error, which is not something
we want to encourage people to check for at runtime (e.g. by dynamically
checking for a 0 return value).

This is nowhere near a complete check-through and gi-docgenification of
the signals docs, just a few bits I was looking at anyway.

We install gvariant-specification-1.0.html to `docs_dir` but that shouldn't require `enable_gir`.
