D-Bus has an upper limit on number of Match rules and it's rather easy to hit
with a big number of proxies with signal subscriptions. This happens with
NetworkManager with hundreds of devices or connection settings. By passing
G_DBUS_SIGNAL_FLAGS_NO_MATCH_RULE to g_dbus_connection_signal_subscribe(), the
user can call AddMatch with a less granular match instead of a match per every
proxy.
Tests subsequently added by Philip Withnall.
Fixes: #1109
Update several links to allow the remote to use its configured default
branch name, rather than specifying `master` as the default branch name.
This will help avoid breakage if any of these projects rename their
default branch in the future.
Fix a few of the links where they were hitting redirects or had moved.

This is the result of checking each `Returns:` line in these files. I’ve
only considered nullability and not other (potentially missing or
incorrect) annotations.

For the reasons given in the new bit of documentation, GDBusProxy should
not be used for connecting to stateless D-Bus services which may be
restarted at any point.

And improve them externally, where not otherwise set, by setting them
from the function name passed to `g_task_set_source_tag()`, if called by
third party code.
This should make profiling and debug output from GLib more useful.

The fix for bgo#651133 (commit 7e0f890e38) introduced a kind of weak
ref, which had to be thread-safe due to the fact that `GDBusProxy`
operates in one thread but can emit signals in another.
Since that commit, `GWeakRef` was added, which does the same thing. Drop
the custom code in favour of it; this should be functionally equivalent,
but using an RW lock rather than a basic mutex, which should reduce
contention.

Using the generic marshaller has drawbacks beyond performance. One such
drawback is that it breaks the stack unwinding from the Linux kernel due
to having unsufficient data to walk past ffi_call_unixt64. That means that
performance profiling by application developers looks grouped among
seemingly unrelated code paths.
While we can't fix the kernel unwinding here, we can provide proper
c_marshallers and va_marshallers for objects within Gio so that
performance profiling of applications is more reliable.

Names are a message bus feature, so it does not make sense to connect
to NameOwnerChanged when the underlying connection is not a message
bus.
Moreover, g_dbus_connection_signal_subscribe() will also enforce that
condition. Adding this extra check here is helpful to avoid a critical
warning when using GDBusProxy with peer-to-peer connections.

Currently, GDBusProxy:g-name-owner only notifies changes to the unique
name owner of the remote object in case the proxy was constructed for a
well-known name.
That sounds like an artificial restriction, and it's convenient to
connect to notify::g-name-owner if a proxy instance has already been
created for an unique name, instead of additionally using
g_bus_watch_name() to track the owner.
To fix this, always connect to NameOwnerChanged after the proxy is
initialized, instead of only doing so when the proxy was constructed for
a well-known name.

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
proxy->priv->name_owner gets overwritten in async_init_data_set_name_owner() on the
assumption that it will always be NULL when we get there. However,
on_name_owner_changed() can run first, and it does set name_owner.

Commit f10b655 removed the inclusion of gasyncresult.h from gdbusproxy.c,
but gdbusproxy.c uses g_async_result_get_source_object(), which caused a
build warning/error. Fix that.
Sometimes the application doesn't want to autostart a service
when it creates a proxy, but wants the service autostarted when
it makes the first method call. Allow that behavior with a new
flag.

As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.
Back in the far-off twentieth century, it was normal on unix
workstations for U+0060 GRAVE ACCENT to be drawn as "‛" and for U+0027
APOSTROPHE to be drawn as "’". This led to the convention of using
them as poor-man's ‛smart quotes’ in ASCII-only text.
However, "'" is now universally drawn as a vertical line, and "`" at a
45-degree angle, making them an `odd couple' when used together.
Unfortunately, there are lots of very old strings in glib, and also
lots of new strings in which people have kept up the old tradition,
perhaps entirely unaware that it used to not look stupid.
Fix this by just using 'dumb quotes' everywhere.
