d65c8c30a9 GDBus: Add G_DBUS_METHOD_INVOCATION_HANDLED, _UNHANDLED
Like G_SOURCE_REMOVE and G_SOURCE_CONTINUE, these make it clearer what
it means to return TRUE or FALSE.

In particular, in GDBus methods that fail, the failure case still needs
to return TRUE (unlike the typical GError pattern), leading to comments
like this:

    g_dbus_method_invocation_return_error (invocation, ...);
    return TRUE;    /* handled */

which can now be replaced by:

    g_dbus_method_invocation_return_error (invocation, ...);
    return G_DUS_METHOD_INVOCATION_HANDLED;

G_DBUS_METHOD_INVOCATION_UNHANDLED is added for symmetry, but is very
rarely (perhaps never?) useful in practice.

00bfb3ab44 tree: Fix various typos and outdated terminology
This was mostly machine generated with the following command:
```
codespell \
    --builtin clear,rare,usage \
    --skip './po/*' --skip './.git/*' --skip './NEWS*' \
    --write-changes .
```
using the latest git version of `codespell` as per [these
instructions](https://github.com/codespell-project/codespell#user-content-updating).

Then I manually checked each change using `git add -p`, made a few
manual fixups and dropped a load of incorrect changes.

There are still some outdated or loaded terms used in GLib, mostly to do
with git branch terminology. They will need to be changed later as part
of a wider migration of git terminology.

If I’ve missed anything, please file an issue!

d955719f04 gdbus-codegen: Allow decorating symbols in headers
This adds three options to gdbus-codegen so that we may be able to
use a self-defined symbol decorator, such as _GLIB_EXTERN, to decorate
the generated prototypes, to be used possibly to export the symbols, if
needed.

The other two options allows including headers that are required for the
specified symbol decorator to be usable and preprocessor macros that are
required for the symbol decorator to be defined appropriately, also when
needed.

2a605f6e15 gdbus-codegen: Add call_flags and timeout_msec args
Currently the code generated by gdbus-codegen uses
G_DBUS_CALL_FLAGS_NONE in its D-Bus calls, which occur for each method
defined by the input XML, and for proxy_set_property functions. This
means that if the daemon which implements the methods checks for
G_DBUS_FLAGS_ALLOW_INTERACTIVE_AUTHORIZATION and only does interactive
authorization if that flag is present, users of the generated code have
no way to cause the daemon to use interactive authorization (e.g. polkit
dialogs).

If we simply changed the generated code to always use
G_DBUS_FLAGS_ALLOW_INTERACTIVE_AUTHORIZATION, its users would have no
way to disallow interactive authorization (except for manually calling
the D-Bus method themselves).

So instead, this commit adds a GDBusCallFlags argument to method call
functions. Since this is an API break which will require changes in
projects using gdbus-codegen code, the change is conditional on the
command line argument --glib-min-version having the value 2.64 or
higher.

The impetus for this change is that I'm changing accountsservice to
properly respect G_DBUS_FLAGS_ALLOW_INTERACTIVE_AUTHORIZATION, and
libaccountsservice uses generated code for D-Bus method calls. So
these changes will allow libaccountsservice to continue allowing
interactive authorization, and avoid breaking any users of it which
expect that. See
https://gitlab.freedesktop.org/accountsservice/accountsservice/merge_requests/46

It might make sense to also let GDBusCallFlags be specified for property
set operations, but that is not needed in the case of accountsservice,
and would require significant work and breaking API in multiple places.

Similarly, the generated code currently hard codes -1 as the timeout
value when calling g_dbus_proxy_call*(). Add a timeout_msec argument so
the user of the generated code can specify the timeout as well.

Also, test this new API. In gio/tests/codegen.py we test that the new
arguments are generated if and only of --glib-min-version is used with a
value greater than or equal to 2.64, and in gio/tests/meson.build we
test that the generated code with the new API can be linked against.

The test_unix_fd_list() test also needed modification to continue
working now that we're using gdbus-test-codegen.c with code generated
with --glib-min-version=2.64 in one test.

Finally, update the docs for gdbus-codegen to explain the effect of
using --glib-min-version 2.64, both from this commit and from
"gdbus-codegen: Emit GUnixFDLists if an arg has type `h` w/
min-version".

Previously, method and signal arguments were sorted by name, which
(assuming you don't happen to give your arguments

incorrect when there is more than 1 argument.

While sorting the methods and signals themselves (and properties, and
annotations on all these) is fine, it's easiest to not sort anything.

8916874ee6 codegen: Add --interface-info-[body|header] modes
These generate basic .c and .h files containing the GDBusInterfaceInfo
for a D-Bus introspection XML file, but no other code (no skeletons,
proxies, GObjects, etc.).

This is useful for projects who want to describe their D-Bus interfaces
using introspection XML, but who wish to implement the interfaces
manually (for various reasons, typically because the skeletons generated
by gdbus-codegen are too simplistic and limiting). Previously, these
projects would have had to write the GDBusInterfaceInfo manually, which
is painstaking and error-prone.

The new --interface-info-[body|header] options are very similar to
--[body|header], but mutually exclusive with them.

98f86beed6 gdbus-codegen: Only generate autocleanup when instructed to
This adds a new --c-generate-autocleanup option to gdbus-codegen
which can be used to instruct gdbus-codegen about what autocleanup
definitions to emit.

Doing this unconditionally was found to interfere with existing
code out in the wild.

The new option takes an argument that can be
none, objects or all; to indicate whether to generate no
autocleanup functions, only do it for object types, or do it
for interface types as well. The default is 'objects', which
matches the unconditional behavior of gdbus-codegen on the 2.48
branch.

1c6cd5f0a3 codegen: make g_autoptr for the GInterface conditional
Some GNOME projects unconditionally work around the generated code's
lack of g_autoptr support by defining the autoptr cleanup function
themselves, which is not forward-compatible; as a result, commit
cbbcaa4 broke them. Do not define the cleanup function unless the
including app "opts in" to newer APIs via GLIB_VERSION_MAX_ALLOWED.

Projects requiring compatibility with GLib < 2.49 can get a
forward-compatible g_autoptr for a generated GInterface type found in
a library, for example ExampleAnimal in the GIO tests, by declaring
and using a typedef with a distinct name outside the library's
namespace:

    typedef AutoExampleAnimal ExampleAnimal;
    G_DEFINE_AUTOPTR_CLEANUP_FUNC (AutoExampleAnimal, g_object_unref)

    ...

    g_autoptr (AutoExampleAnimal) animal = NULL;
