g_icon_new_for_string() docs states that it should return a single name
when created with a single name. I add a second condition to this case:
the themed icon must not include default fallbacks (i.e. it must not
have been created with `g_themed_icon_new_with_default_fallbacks()`).
Otherwise the return value of `g_icon_new_for_string()` would not
recreate the same icon list when passed to `g_icon_new_for_string()`
(which would be another documentation inconsistency).

g_icon_new_for_string() is now back to old behavior for this specific
case.

I also revert the unit test for this case, and add a new unit test when
using g_themed_icon_new_with_default_fallbacks() with a single name as
well.

Closes #1513.

This is also faster, though I doubt anyone's able to measure it.

The previous code was a more complicted way to do the same thing and it
was likely written the more complicated way because it fell out commit

https://bugzilla.gnome.org/show_bug.cgi?id=795307

Expands to the GNU C fallthrough statement attribute if the compiler is gcc.
This allows declaring case statement to explicitly fall through in switch
statements. To enable this feature, use -Wimplicit-fallthrough during
compilation.

We have git for that.

automake requires a ChangLog file in gnu mode so switch to the less strict
foreign mode instead.

They only contain old information which is also available in git

It might not be immediately obvious that this is the case. Let's record
it in the description of `GTimeVal` itself and also in
`g_time_val_from_iso8601`.

We also drop an incorrect statement in the documentation for
`g_time_val_from_iso8601` stating that years up to 3000 were supported;
this is also not true for the same reason.

tests/timer: Skip test_timeval_to_iso8601_overflow if we can't overflow a GTimeVal

Closes #1509

See merge request !299

On 32 bit systems, the size of a long might be the same as the size of
an int. In that case, we won't be able to get an overflow when
converting from a GTimeVal to a time_t. Skip the test for this in that
case.

Closes #1509

We already set -Wformat=2, which implies -Wformat-security, so there’s
no need to test for and set -Wformat-security separately.

The test for -Wformat-security never worked anyway, since gcc complains
if it’s specified without also setting -Wformat to some value. The
complaint causes configure.ac/meson.build to assume the option doesn’t
work.

There are many cases where a default TLS database is not able to be
defined within the constraints of a system.  For example glib-networking
(or glib-openssl) cannot retrieve the default certificate store on iOS
or Android and need to be initialized from a cert file of certificates
bundled with the application.

Previously GStreamer was relying on a custom patch to glib-networking to
populate the default database from the file pointed to by the
CA_CERTIFICATES environment variable however the mechanism that enabled
this was recently remove from glib-networking.

Adding a more generic g_tls_backend_set_default_database() API allows
application developers to override the default database using their own
certificates as well as allowing equivalent functionality on Android/iOS
(or others) as on the default database handling Linux.

Fixes glib-networking#35

The ::network-changed signal is documented to indicate any change in
network configuration, which doesn't necessarily imply a property
change - additional services becoming available after connecting to
a VPN comes to mind for instance.

In order to match the "native" network monitor's behavior, always
emit the signal when it's in response to the 'changed' D-Bus signal.

Also emit the signal unconditionally when loading the initial property
values, to allow clients to differentiate between "offline" meaning
"offline" and "offline" meaning "uninitialized".
