Also, g_input_stream_read_async() was now leaking its cancellable. Fix

If the launch context is a GAppLaunchContext, and not a
GdkAppLaunchContext, then g_app_launch_context_get_display will return
NULL because the get_display virtual method is undefined. The DISPLAY
might still be inherited from the parent process, in which case
overwriting it with NULL breaks the launch.

If all members of GSocketFamily are supported on the platform, then
all of its values will be positive, and so the enum might become
unsigned, in which case testing for "family < 0" might cause warnings.
But we want to return an error if family == 0 (aka
G_SOCKET_FAMILY_INVALID) anyway, so just tweak the test accordingly.

gdbus-daemon-generated.[ch] failed to build because it depended
on gdbus-2.0/codegen/gdbus-codegen which was build during the SUBDIRS part
of the build, however SUBDIRS are done *after* processing BUILT_SOURCES,
and these files are in BUILT_SOURCES.
The fix is simple, instead of running the gdbus-codegen code we
run the gdbus-codegen.in code, which works fine for uninstalled execution.
I also removed Makefile from the dependencies to avoid rebuilding the file
in tarballs, as Makefiles are written at configure time. We should be able to
ship the prebuilt files in the tarballs.

Add two new methods to GProxyAddress for recovering information about
the destination URI that the proxy was created for (and modify
GProxyAddressEnumerator to set that information when creating the
GProxyAddress).
In the async case, a failed DNS lookup was causing the proxy
resolution to bail out immediately, rather than just moving on to the
next potential proxy (which might not need us to do the DNS lookup
beforehand). Fix that.
This is mostly complete, sans support for activation. However, its
not as picky as the libdbus implementation in terms like validation
and limits checking, nor is it as tested.
Its can be useful to test gdbus if dbus-daemon is not availible, but
its main reason for existance is to implement a default session bus
on win32 so that e.g. GApplication is guaranteed to work.
If a GInputStream does not provide a read_async() implementation, but
does implement GPollableInputStream, then instead of doing
read-synchronously-in-a-thread, just use
g_pollable_input_stream_read_nonblocking() and
g_pollable_input_stream_create_source() to implement an async read in
the same thread. Similarly for GOutputStream.
Remove a bunch of existing read_async()/write_async() implementations
that are basically equivalent to the new fallback method.

Make g_pollable_input_stream_read() and
g_pollable_output_stream_write() look a little bit more like the
non-pollable versions in terms of error handling, etc. Also, use the
read_fn and write_fn virtual methods directly rather than calling
g_input_stream_read()/g_output_stream_write(), to avoid problems with
re-entrancy involving the "pending" flag.
Also belatedly add single-include guards to the header files.

The loop was using a GConverterResult variable where it meant to use a
gssize, and since GConverterResult was ending up as an unsigned type,
this meant the (res < 0) check always failed.
Resources are always little endian, so the gvdb is byteswapped. When looking
up the value, it would return a new byteswapped variant, making the data
returned from do_lookup() invalid once that variant is unref'd. Since
byteswapping doesn't matter for the "ay" data anyway, just use
gvdb_table_get_raw_value() instead and only byteswap the length and flag
values.

This patch solves two problems:
First, it allows builders to optionally cut the circular dependency
between dbus and glib by disabling the modular tests (just like how
the tests can be disabled in dbus).
Second, the tests are entirely pointless to build if cross-compiling.
It also moves us slightly closer to the long term future we want where
the tests are a separate ./configure invocation and run against the
INSTALLED glib, not the one in the source tree. This would allow us to
run the tests constantly, not just when glib is built.

For quite some time the recommended usage of GSettings and dconf has
been to use paths like /org/gnome/example/. Use of /apps/ has spilled
over from GConf and is continuing to make its way into a number of
applications as they port.
glib-compile-schemas will now warn about these types of paths being
used. This generates a lot of noise, but hopefully it will reduce the
number of ported applications making this mistake.
Turns out libdbus doesn't send struct ucred credentials on linux, but
just relies on the SO_PEERCRED support. However, gdbus does send, and
expect to recieve a ucred credential. So, when libdbus talks to a
gdbus server the authentication fails to send the credentials.
We fix this by falling back to g_socket_get_credentials() if we don't
get any credential messages.
When presented with an array of empty arrays of 8-byte-aligned types,
GDBus would incorrectly apply the 8-byte alignment when reading back.

D-Bus arrays are serialized as follows:
1. align to a 4-byte boundary (for the length)
2. uint32: the length of the serialized body in bytes
3. padding for the alignment of the body type (not included in the length)
4. the body.
Note that 3. is a no-op unless the body type is an 8-byte aligned type
(uint64, int64, double, struct, dict_entry), since you are always on a
4-byte boundary from aligning and writing the length.
So, an empty aax (that is, an array containing zero arrays of int64)
is serialized as follows:
1. align to a 4-byte boundary
2. length of the contents of this (empty) array, in bytes (0)
3. align to a 4-byte boundary (the child array's alignment requirement)
4. there is no body.
But previously, GDBus would recurse in step three to align not just for
the type of the child array, but for the nonexistent child array's
contents. This only affects the algorithm when the grandchild type has
8-byte alignment and the reader happened to not already be on an 8-byte
boundary, in which case 4 bytes were spuriously skipped.

GDBus heavily relies on idles for some of its cleanup operations,
and not running a mainloop leads to things not getting cleaned
up properly, which in turn leads to test failures, since the
session bus singleton does not get removed.
This program is only used indirectly from gapplication.c in
tests, but that is no reason to let it segfault when it is
run from the commandline without arguments.
This is needed because glib-mkenums doesn't handle #ifdef values in
enums, and so it needs to have all values always defined in the enum.
When not available, define the missing values to a negative value.
g_input_stream_read() does state that it returns 0 on end of file, but
not in the Returns: line, so it's easy to miss on a quick skim-read.
g_input_stream_read_async() documents that g_input_stream_read_finish()
returns 0 on end of file, but g_input_stream_read_finish() itself does
not.

a GCancellable that is checked for being cancelled during the call to

that a positive result has occured and is pending dispatch at the time
the operation is cancelled.

We were attempting to unregister our ownership of our D-Bus name even in

non-NULL.
If an application (such as Nautilus) wants to show a sidebar with
devices group into different groups such as "Devices" and "Network",
it's currently up to the application itself to do the classification
