We currently assume that the OpenURI portal should be used
unconditionally when running inside a flatpak sandbox. While
the portal is what we usually want, there are exceptions:
Yelp is now included in the GNOME runtime to allow displaying
help without exporting the user documentation, and the sandboxed
app itself may register a scheme handler.
To account for those cases transparently, always try the normal
code path first and only fall back to calling the portal when
that fails.

These calls cause race warnings from tsan, but are not a thread safety
problem, because we can only ever observe single bit changes: all
modifications to the GSource.flags field are done with a lock held; all
reads are of independent fields, so no intermediate state can ever be
observed. This assumes that a non-atomic read will consistently give us
an old value or a new value.
In any case, these g_source_is_destroyed() calls can happen from any
thread, and the state could be changed from another thread immediately
after the call returns; so the checks are pointless. In addition,
calling g_source_set_ready_time() or g_source_destroy() on a destroyed
source is not a problem.
https://bugzilla.gnome.org/show_bug.cgi?id=778049
Calling the D-Bus method for the OpenURI portal "protects" the logic from
not ever having the remote method running in case the xdg-desktop-portal
process is not yet running and the caller quits quickly after the call.
This should not be a problem as the method returns immediately (regardless
of the user making a selection), but making it synchronous would prevent
situations where the OpenURI method would never be called because of D-Bus
dropping the message after the caller dies, without explicitly waiting for
a reply.

Previously, _kh_cancel_sub assumed that it only needed to call
_km_remove if sub did not exist in subs_hash_table. This is erroneous
because the complementary operation, _km_add_missing, can be called
from process_kqueue_notifications, in which context sub can *only* have
come from subs_hash_table.
Since _km_remove is implemented using g_slist_remove, which is
documented to be a noop if the list does not contain the element to be
removed, it is safe to call _km_remove unconditionally here.

It was suggested that the project files be moved here as we don't actually
need to go two directory layers from $(srcroot), and would help us to
standardize on things in the future across the board.
When performing the verify and building the error string there were two
possibilities of an infinite loop. The first is the missing twos-complement
to unset the bit in the filtered flags. The second is the lack of handling
G_SUBPROCESS_FLAGS_NONE which can return a valid GFlagsValue (and cannot
unset the bit since the value is zero).
This walks all known values in the GSubprocessFlags type class and check
if they are set. This has the benefit that we don't call needless functions
which walk the same table as well as avoiding mutating values to build
the error string.

Previously, this would not work, as it would result in comparing the
order of a string and an integer. Make it work, and make 'UNRELEASED'
compare higher than other versions so it's always treated as the latest
version.
'UNRELEASED' is commonly used by maintainers to highlight new API while
it's being prototyped, until they know which version it will actually
be released in. At the time of release, they replace all 'UNRELEASED'
strings in git with the new version number.
An example of this usage is here:

The two known use-cases for autolaunching are:
* X-forwarding: "ssh -Y myhost myapp" resulting in a
session bus on myhost but an X server on the original host
* Legacy desktop environments on OSs without D-Bus integration:
e.g. running a single GNOME or KDE app under fvwm or something,
without a session dbus-daemon being started by either systemd,
gnome-session, or OS integration scripts analogous to Debian's
/etc/X11/Xsession.d/75dbus_dbus-launch
In either case, an X11 DISPLAY is also needed.
"dbus-launch --autolaunch" doesn't do anything useful when unable
to connect to an X11 display; this has been the case since the feature
was added in 2006, and is useful to avoid "split brain" situations in
which two processes that ought to be part of the same session end up
on separate session buses. Since dbus commit 407c111 in 2011,
libdbus hasn't even attempted to run "dbus-launch --autolaunch"
unless getenv("DISPLAY") returns non-null in the parent: this avoids
doing a relatively complicated fork-and-exec that is clearly not
going to lead to success. This commit gives GDBus the same policy.
This change was originally made to work around a race condition in
subprocess spawning (Debian bug #737380, GNOME bug #711090) but
it seems valid in its own right.
In my opinion as D-Bus maintainer, "dbus-launch --autolaunch" should
be considered to be an X11 feature, and any future D-Bus enhancements
(e.g. kdbus) or successors for X11 (e.g. Wayland, Mir) should obtain
a session bus address by other means - either a session manager
such as "systemd --user", gnome-session or Upstart, or a wrapper
for the user session like dbus-run-session(1).
