This is the right thing to do for the "a session is a user-session"
model implemented in dbus 1.9.14, which is described in
<http://lists.freedesktop.org/archives/dbus/2015-January/016522.html>.
It also resembles sd-bus' behaviour, although sd-bus will only try
kdbus and XDG_RUNTIME_DIR/bus, and never runs dbus-launch.
On systems following the more traditional "a session is a login-session"
model, X_R_D/bus won't exist, so it is harmless to check for it before
falling back to X11 autolaunching. Again, this matches the behaviour
of current libdbus and sd-bus versions.
Now that we do this, g_test_dbus_unset() needs to clear XDG_RUNTIME_DIR
as well as everything else.

This only alters what happens if we specifically connect to
"autolaunch:", for instance via "DBUS_SESSION_BUS_ADDRESS=autolaunch:".
We will still potentially try other platform-specific things if
DBUS_SESSION_BUS_ADDRESS is unset. There are currently no other
platform-specific things, so there is no practical difference yet,
but I'm about to add a more-preferred fallback path before autolaunch.
This matches libdbus' behaviour and the D-Bus Specification, in which
the autolaunch: transport specifically means X11 autolaunch
(as implemented by "dbus-launch --autolaunch") on Unix, or a
shared-memory-based protocol on Windows. Other platform-specific
transports or default/fallback modes, including launchd on Mac OS X
and XDG_RUNTIME_DIR/bus on Unix, are not part of "autolaunch:".
It's rather unfortunate that the same name means two different
platform-specific mechanisms, specific to different platforms -
if they were added today I'd call them x11: and windows-shm: or
something - but it's been like this since 2007 so it's too late now.

Normally, recent PCRE behaves as if certain patterns were replaced
by a more "possessive" pattern that gives the same answer for normal
regex matching, but is more efficient. However, the modified pattern
produces fewer results under DFA. If we want the full set of results
we have to apply PCRE_NO_AUTO_POSSESS, and that's a compile-time flag.
This currently only affects a system PCRE, but would also work fine for
an internal PCRE 8.34 or later if the embedded copy is updated.

Currently, applications using g_application_add_main_option_entries()
won't get translated entries in --help output. We need to call
g_option_group_set_translation_domain() with a NULL domain to ensure that the
default application gettext domain (ie the one passed to the
textdomain() call) will be used for the main entries passed by the
application.
If we want to allow more flexibility on which gettext domain should be
used for these entries, new API will be needed.

Add a new section to the main GSettings documentation which documents

interconnected structures in several hash tables
- Watch the registry keys, re-scan the registry when any one of them changes.

Use the newly added g_settings_schema_list_keys() API instead of
g_settings_list_keys() in order to list keys.
Doing this allows the 'list-keys' command to work without creating a
GSettings object, which is more efficient. It also means that we don't
have to provide a (meaningless and ignored) path when listing keys on
relocatable schemas.
While we're at it, update the 'range' command not to require creation of
a GSettings object, in a similar way.
https://bugzilla.gnome.org/show_bug.cgi?id=740308
The list of keys in a GSettings object depends entirely on the schema,
so it makes sense to expose this API there.
Move the implementation out of gsettings.c and into gsettingsschema.c,
replacing the earlier with a simple call to the new location.
We don't do the same for children because the children can change.

Cancellation of GPollFileMonitor is now handled correctly (in the sense
that no further signals will follow) but let's be extra paranoid and
disconnect our handler anyway, for good measure.
https://bugzilla.gnome.org/show_bug.cgi?id=739424
GPollFileMonitor emits CHANGES_DONE_HINT after CHANGED signals, but it
doesn't check to ensure that the file monitor wasn't cancelled before it
does that.
If the original signal caused the monitor to be unreffed, cancelled and
destroyed, we would still end up emitting an extra signal on it.
Avoid that by checking first for cancellation.

Removed all mentions of GLib file name encoding referring to
the environment strings. The env var content has no defined relation
to GLib's notion of filename encoding, or any encoding whatsoever.
It would be wrong to pass all UTF-8 strings through
g_filename_from_utf8() in order to put them into the environment,
for one thing.

DBus has recently introduced new message flag

In order to maintain a logical stream of events, we need to make sure we
flush and queued change notifications before responding to any requests
for information from clients.
If we don't do this, it's possible that we emit an 'add' event that was
queued at the time of a 'DescribeAll' call _after_ the reply to that
call (which already contained the description of the new action).
In practice, this is not only logically incorrect, but it can also cause
problems. If a change to action 'state' or 'enabled' occurs after the
DescribeAll but before the signal has been dispatched, it will be
ignored because an 'add' signal is already pending. When that add
signal is sent, it will contain the correct data, but the receiver will
ignore it because it already saw the action in the DescribeAll reply.

This is a hack for GLocalFileInfo to correctly get icons for directories.
Without this change content type for any W32 directory is NULL
(because there's no registry entry for "inode/directory" by default,
and in any way there's no file extension that means "directory" to put there),
and GLocalFileInfo uses content type to grab icons.

The code here was returning gtk-directory and similar names as
fallback, with a comment claiming that these are 'builtin gtk'.
But they aren't, anymore, so just return the standard names.
Prevents race condition in function g_io_condition_get_type by ensuring
that the initialization section for 'etype' is executed only once
during a program's life time, and that concurrent threads are blocked
until initialization completes. This changes solves the problem that
concurrent threads could execute the check 'etype == 0' before any of
them had initialized it, which in turn meant that multiple threads
would then attempt to register the "GIOCondition" type.

This code used to look at the SCM_CREDENTIALS and ignore every message
not from uid 0. However, when user namespaces are in use this does not
work, as if uid 0 is not mapped you get overflowuid instead. Right now
this means we ignore all messages in such user namespaces and glib
apps hang on startup.
We can't look at pids either, as pid 0 is returned for processes
outside your pid namespace.
Instead the correct approach is to look at the sending sockaddr and
if the port id (nl_pid) is zero, then its from the kernel.
