The threaded tests are using the default main context in the worker
thread, but were not g_main_context_acquire()ing it first, which meant
that g_tls_interaction_invoke_ask_password() in the main thread would
sometimes succeed in acquiring it itself and thus performing the
operation in the wrong thread. Fix that.
Also, we can't unref the loop from the worker thread, because the main
thread isn't holding a reference on it, and so it might end up being
destroyed while that thread is still inside g_main_loop_quit().
(which shouldn't ever have been part of the API. Grr.)
Solaris /etc/services doesn't even have "http", which was causing
tests/network-address to fail...
On Solaris, getsockname() on an unconnected socket gives an addrlen of
0 and doesn't set the sockaddr. So use the SO_DOMAIN sockopt to find
the socket family in that case. (SO_DOMAIN doesn't exist everywhere,
so we can't use it unconditionally. Also, we have to only use it if
getsockname() fails, since SO_DOMAIN returns a bogus value for
accept()ed sockets on both Linux and Solaris...)
Also, link libgio to -lresolv explicitly, rather than depending on
getting it implicitly via the libasyncns build (which should
eventually be going away).

from any thread. The interaction will be run in the appropriate
#GMainContext
* Sync methods can be called whether main loop is running or not.
* Derived classes can choose to implement only sync or async

g_desktop_app_info_set_as_default_for_type() and
g_desktop_app_info_set_as_last_used_for_type () require the
application's ID, but depending on how the GAppInfo was created,
we might not be have one, and would thus silently fail to set
the default application, or last used application.

The test was using a socket in a temporary directory, but not actually
creating that temporary directory. This worked fine on Linux since it
actually ended up using an abstract socket instead, but failed on
unixes without abstract sockets.

The docs for g_socket_set_timeout() claimed that if an async operation
timed out, the GIOCondition passed to the source callback would be
G_IO_IN or G_IO_OUT (thus prompting the caller to call
g_socket_receive/send and get a G_IO_ERROR_TIMED_OUT), but in fact it
ended up being 0, and gio/tests/socket.c was erroneously testing for
that instead of the correct value. Fix this.
* Load modules from paths listed in GIO_EXTRA_MODULES environment
variable first.
* Ignore duplicate modules based on module basename.
* Add the concept of GIOModuleScope which allows other callers to
skip duplicate loaded modules, or block specific modules based on
basename.
* Document behavior.

on GTlsInteractionClass because we're going to need it.

Rework property getters to use a vfunc so we can take the fast path
and avoid allocating memory for both the skeleton and the proxy
cases. This requires some special case because of how GVariant expects
you to free memory in some cases, see #657100. Add test cases for
this.
Document the _get_ functions as not being thread-safe and also
generate _dup_ C getters (which are thread-safe).
Mark all the generated _get_, _dup_ and _set_ as (skip) as non-C
languages should just use GObject properties and not the (socalled)
"C binding".

The main rationale for adding it was to avoid having gnome-shell
mmap'ing /etc/localtime once a second. However, we can just as easily
run inotify there, and given no one else was clamoring for a way to
detect when the time zone changes, I don't see a need for public API
here - at least not yet.
In the bigger picture, I just don't believe that the vast majority of
applications are going to go out of their way to instantiate and keep
around a random GTimeZoneMonitor class. And if they do, it's has the
side effect that for other bits of code in the process, local GDateTime
instances may start varying again!
So, if code can't rely on local GDateTime instances being in a
consistent state anyways, let's just do that always. The
documentation now says that this is the case. Applications have
always been able to work in a consistent local time zone by
instantiating a zone and then using it for GDateTime constructors.
We fix the "gnome-shell stats /etc/localtime once a second" issue by
using timerfd (in glib) and inotify (in gnome-shell).

This changes the meaning of "properties_lock" from "lock for D-Bus
properties" to "lock for GObject properties".
The most common problem, and the only one I've reproduced in a regression
test, is name_owner, which can be updated by the thread that owns
the GDBusProxy's main context (i.e. the thread-default main context of
the thread that constructed it) at the same time that a blocking call
is made. When a GDBusProxy is constructed in a thread-pool thread for
short-term use, the main context will typically be the global default
main context (which is actively running in the main thread!), making
this extremely problematic.
The interface info is perhaps a theoretical concern - one thread could
conceivably set it at the same time that another thread uses it, but only
in relatively pathological situations. The current API for this does have
the problem that it returns a borrowed ref, but interface info is
hopefully permanent anyway.
The default timeout is probably only a theoretical concern - it's just an
int, so writes are indivisible, and there's no worry about whether
something has been freed - but to be safe, let's hold the lock for that
too.

This removes the need for async_init_get_name_owner_cb to cope with being
called without a real GAsyncResult, and will simplify the addition of
correct thread-locking.
In async_init_data_set_name_owner, use the name_owner parameter instead
of the corresponding member of GDBusProxyPrivate, partly to reduce
pointer-chasing but mainly to avoid needing to hold the lock.

If you run:
( cd gio/tests && G_DBUS_DEBUG=all ./gdbus-proxy-well-known-name )
you can see that in the case where the name com.example.TestService isn't
owned yet, the GDBusProxy calls GetAll() with no destination, resulting
in an error reply from the peer (the dbus-daemon itself). That's clearly
not right!
However, if priv->name is NULL, that indicates the special case where we
really do want to talk directly to a peer, instead of via the bus daemon
(most likely to be used on peer-to-peer connections); in that special
case, do call GetAll().

This avoids calling g_variant_unref and g_free on uninitialized memory
if PropertiesChanged is received in the creating thread's thread-default
main context's thread, at the same time as releasing the last ref in
another thread. This would result in "goto out" before the variables
freed after that label had been initialized to NULL.

socket->priv->connected was only being set if g_socket_connect()
succeeded right away; in the case where it returns G_IO_ERROR_PENDING,
it never got set. Fix that by having g_socket_check_connect_result()
set it on success.
Otherwise, we may run into trouble as opening a peer-to-peer
connection uses a socket client, which uses a proxy resolver
which may end up using gsettings, whose dconf backend may end
up using the session bus to talk to dconfd...
Also add convenience _with_unix_fd_list variants to GDBusConnection,
GDBusProxy and GDBusMethodInvocation types to easily support this.

This function implements the following logic:
if (g_variant_is_floating (value))
g_variant_ref_sink (value);
which is used for consuming the return value of callbacks that may or
may not return floating references.
This patch also replaces a few instances of the above code with the new
function (GSettings, GDBus) and lifts a long-standing restriction on the
use of floating values as the return value for signal handlers by
improving g_value_take_variant().
