This makes use of the string we now have from glib-private.h in the
last commit so that setlocale() sets the default system locale
correctly and therefore show the translated messages properly.
Fixes issue #1169.
Using the generic marshaller has drawbacks beyond performance. One such
drawback is that it breaks the stack unwinding from the Linux kernel due
to having unsufficient data to walk past ffi_call_unixt64. That means that
performance profiling by application developers looks grouped among
seemingly unrelated code paths.
While we can't fix the kernel unwinding here, we can provide proper
c_marshallers and va_marshallers for objects within Gio so that
performance profiling of applications is more reliable.
Related to GNOME/Initiatives#10
If c_marshaller is provided during g_signal_new() registration, the
automatic va_marshaller will not be set. If we leave the c_marshaller as
NULL in the simple cases, both a c_marshaller and va_marshaller will be
set for us.
This is particularly helpful when dealing with stack traces from Linux
perf, which often cannot unwind the stack beyond the ffi_call_unix64
stack-frame on x86_64.

This ensures that D-Bus connections established with unix:dir and
unix:path addresses actually work properly. Previously, we only tested
unix:tmpdir and TCP addresses.
This is not going to have much any effect currently since stop() just
disconnects a signal handler (that is going to be disconnected in
finalize anyway) and stops the socket service (that is going to be
destroyed in finalize), but it makes sense to do here for robustness.
unix:dir= addresses are exactly the same as unix:tmpdir= addresses,
already supported by GDBus, except they forbid use of abstract sockets.
This is convenient for situations where abstract sockets are
impermissible, such as when a D-Bus client inside a network namespace
needs to connect to a server running in a different network namespace.
An abstract socket cannot be shared between two processes in different
network namespaces.
Applications could use unix:path= addresses instead, so this is only a
convenience, but there's no good reason not to support unix:dir=.
Currently it is not supported simply because unix:dir= is a relatively
recent addition to the D-Bus spec.
It's somewhat unrealistic to use a GDBusServer without a
GDBusAuthObserver, because most D-Bus servers want to be like the
standard session bus (the owning user can connect) rather than being
like the standard system bus (all users can connect, the server is a
security boundary, and many bugs are security vulnerabilities).

This is simpler and more robust than DBUS_COOKIE_SHA1, which relies
on assumptions about random numbers and a secure home directory.

Authentication is about proving who I am; authorization is about
whether, given the knowledge of who I am, I am allowed to do something.
GDBusServer and GDBusConnection carry out authentication automatically,
but rely on the library user to carry out authorization.

Previously, its tests were being run in the build directory, which is
fine (it should always be writable). If multiple tests were run in
parallel, for example with Meson’s `--repeat` option, their test files
would collide.
Fix that by running each test instance in a separate subdirectory of
`/tmp`.

Helps: #1634
Add a case for when the IPv6 result comes back negative and the IPv4
result is significantly delayed. This is exactly the case that causes
the bug addressed by GNOME/glib!865
The "happy eyeballs" RFC states that on receiving a negative response
for an IPv6 address lookup, we should wait for the IPv4 lookup to
complete and use any results we get from there.
The current code was not doing that: it was rather setting a timeout for
failing the resolution entirely. In scenarios where the IPv4 response
comes more than 50ms after the IPv6 response (which is easily attainable
under valgrind in certain configurations) this means that the IPv4
response will never come.
Remove the timeout and just wait.

It should produce a generic result, but not crash. It was previously

This was introduced in commit 7846d6154a: g_subprocess_get_identifier()
will return NULL after the subprocess has exited, and the subprocess in
the `noop` test will exit as soon as it has started spawning. So if the
scheduler scheduled the testprog subprocess quickly, descheduled the
parent test process until the testprog exited, then the return value
from g_subprocess_get_identifier() would be NULL.
Move the g_subprocess_get_identifier() test to one which calls testprog
in `sleep-forever` mode, since that is guaranteed not to exit until
killed (which we do later in the test).

The most useful ones were already listed in the pkg-config file, but
some others (notably, `gio-querymodules`) were not. List them in the
pkg-config file with their installed paths so that the right binary is
used if GIO is installed in a non-default path.

`NM_STATE_CONNECTED_SITE` is documented to mean that a default route is
available, but that the internet connectivity check failed. A default
route being available is compatible with the documentation for
GNetworkMonitor:network-available, which should be true if the system
has a default route for at least one of IPv4 and IPv6.
