This should introduce no functional changes. Factor out some common
code, flip some arguments around to use the more conventional (data,
length) order, and move some memory management calls out of
if-blocks.

By using g_timeout_source_new_seconds(), we can let timer wakeups be
coalesced by the scheduler, and reduce power consumption a bit. This
shouldn’t really affect the accuracy of the network monitoring.

Previously, the GSource would be attached to whatever GMainContext was
the thread default at the time; but that might no longer be the same as
the default at the time of constructing the GNetworkMonitor.
Save the default from construction time, so that source callbacks are
always invoked in the same GMainContext.

In this situation:
$ gdbus emit --session --object-path /org/foo/bar --sig<tab><tab><tab>
We will currently insert --signal three times.
We should only do that once.
https://bugzilla.gnome.org/show_bug.cgi?id=793597
Commit faf9440908 made the bash completion more
robust, but in doing so it made the optional --dest argument to `gdbus emit'
mandatory by mistake.
Remove the error case when --dest is not specified. To keep the completion
working, we shuffle the cases around. --dest should be offered up for
completion after --session/--system/--address have been supplied, so we can
complete its argument. Additionally, if --dest isn't specified then we can't
complete --object-path or --signal, so guard these completions accordingly.
https://bugzilla.gnome.org/show_bug.cgi?id=793597
When completing, we parse the options that the user has typed so far. Up
until now we've been doing this without ignoring unknown options. This
leads to broken completions when the user has typed an incomplete
parameter.
For example, when doing the following:
$ gdbus emit --session --obj<tab>
We expect --object-path to be completed, but it is currently not. What
happens is that we fail to parse the options, therefore don't act on
--session and so don't connect to the session bus, then we early-exit
because we need to know which bus to operate on for later completions.
Instead we can ignore the half-completed --obj, parse --session, get
connected to the bus and then move on to the later completion code.

It incorrectly said that an error could only be returned if the GVariant
was incorrect for the D-Bus API, but that’s not true: an error will also
be returned if you call it on a closed GDBusConnection.
Clarify that, and mention the actual error codes which are returned.

If calling g_subprocess_communicate() on a GSubprocess with no
stdout/stderr pipe, a critical warning would be emitted from
g_memory_output_stream_steal_as_bytes(), as it would be called on a NULL
output stream.
Fix that, improve the relevant GIR annotations, and expand the unit
tests to cover it (and various other combinations of flags).

Building against libmount installed into a non-default prefix wasn’t
working, as we were using #include <libmount/libmount.h> rather than
the correct #include <libmount.h> — all the mount.pc pkg-config files
set `Cflags: -I${includedir}/libmount`.
Fixing this while retaining the fallback support for versions of
libmount without a pkg-config file would have been tricky (we would need
to work out a suitable -I flag to set in LIBMOUNT_CFLAGS) to still be
able to use the correct #include path). Thankfully, libmount gained
pkg-config support a long time ago, so I think we can safely drop the
fallback code. In particular, Debian Jessie, Ubuntu Trusty, and CentOS 5
all ship a mount.pc file.

g_variant_get_objpathv() doesn’t exist. The code actually meant

res_query() uses global state in the form of the struct __res_state
which contains the contents of resolv.conf (and other things). On Linux,
this state seems to be thread-local, so there is no problem. On OS X,
however, it is not, and hence multiple res_query() calls from parallel
threads will compete and return bogus results.
The fix for this is to use res_nquery(), introduced in BIND 8.2, which
takes an explicit state argument. This allows us to manually store the
state thread-locally. If res_nquery() isn’t available, we fall back to
res_query(). It should be available on OS X though. As a data point,
it’s available on Fedora 27.
There’s a slight complication in the fact that OS X requires the state
to be freed using res_ndestroy() rather than res_nclose(). Linux uses
res_nclose().
(See, for example, the NetBSD man page:
https://www.unix.com/man-page/netbsd/3/res_ninit/. The Linux one is
incomplete and not so useful:
http://man7.org/linux/man-pages/man3/resolver.3.html.)
The new code will call res_ninit() once per res_nquery() task. This is
not optimal, but no worse than before — since res_query() was being
called in a worker thread, on Linux, it would implicitly initialise the
thread-local struct __res_state when it was called. We’ve essentially
just made that explicit. In practical terms, this means a
stat("/etc/resolv.conf") call per res_nquery() task.
In future, we could improve this by using an explicit thread pool with
some manually-created worker threads, each of which initialises a struct
__res_state on spawning, and only updates it on receiving
the #GResolver::reload signal.

Some projects use child schemas in an odd way: they link children which
already have their path pre-defined. This causes the child schema (and
its keys) to be printed out twice:
- once because it is, itself, a non-relocatable schema
- once, as a recursion from its parent
We can avoid this by not recursing into child schemas that are
non-relocatable (on the assumption that they will be enumerated
elsewhere).

See the discussion in the bug report: with proxy support enabled, a
proxy resolver is created. Doing that will load all the GIO modules, and
typically at least one of them will try to use GDBus during
initialisation, which will cause a deadlock.
Using a TCP address with GDBusAddress is still supported, but accessing
it over a proxy is not.

In cases where gdbus-codegen is used only for docbook generation,
the execution stops with the following error message:
`Using --header or --body requires --output`
This is because it was assumed that, in addition to the docbook
generation, the header or source code were always generated.
This patch fixes this, and the header or source code generation
is not mandatory, so the docbook can be generated separately.
