AppArmor: do not mix dbus_bool_t with int
libdbus uses dbus_bool_t for booleans; that type is unsigned 32-bit.
However, libapparmor uses int, which is signed, leading to
-Wpointer-sign warnings when we pass a dbus_bool_t * where an int *
was expected.
This file is Linux-specific, and all Linux platforms have 32-bit int
and an in-memory representation of the integers 0 and 1 that is
independent of signedness, so the previous code was harmless
in practice.

Consistently use socklen_t for getsockname, getsockopt etc.
This fixes signedness mismatch warnings on platforms where socklen_t
is unsigned, notably Linux (where it's an unsigned int).
We still use int for the fallback case where the platform does not
define socklen_t, because that was the traditional (pre-POSIX) type:

Do not attempt to call child_setup on Windows
child_setup() is defined to be called after fork() and before exec(),
but Windows' process model does not have fork(): the equivalent of
those two operations is a single CreateProcess() call. This means
that there is no point at which we could call child_setup() and
have it affect only the child's process-global state. At the point
where it is currently executed, it affects the parent's process-global
state instead, which would be actively harmful if we used any
child_setup() function that was not a no-op on Windows.
The equivalent function in GLib, g_spawn_async_with_pipes(), documents
child_setup() as unused on Windows. Do the same here.
In practice, our only use of child_setup() outside tests
is #ifdef DBUS_UNIX anyway, so this change has no practical effect
right now.
