dacfe8c88a param: Add g_param_value_is_valid
This is wrapper for the new value_is_valid vfunc,
but it falls back to using value_validate to
obtain the same information.

dd43471f60 gobject: add GSignalGroup
Much like GBindingGroup, the GSignalGroup object allows you to connect many
signal connections for an object and connect/disconnect/block/unblock them
as a group.

This is useful when using many connections on an object to ensure that they
are properly removed when changing state or disposing a third-party
object.

This has been used for years in various GNOME projects and makes sense to
have upstream instead of multiple copies.

0d9de09192 gobject: add GBindingGroup
Originally, GBindingGroup started with Builder as a way to simplify all
of the third-degree object bindings necessary around Model-Controller
objects such as TextBuffer/TextView.

Over time, it has grown to be useful in a number of scenarios outside
of Builder and has been copied into a number of projects such as GNOME
Text Editor, GtkSourceView, libdazzle, and more.

It makes sense at this point to unify on a single implementation and
include that upstream in GObject directly alongside GBinding.

1a95ce84ed GValue: Add interned string support
This adds support to be able to explicitely stored interned strings into
G_TYPE_STRING GValue.

This is useful for cases where the user:
* *knows* the string to be stored in the GValue is canonical
* Wants to know whther the string stored is canonical

This allows:
* zero-cost GValue copy (the content is guaranteed to be unique and exist
  throughout the process life)
* zero-cost string equality checks (if both string GValue are interned, you just
  need to check the pointers for equality or not, instead of doing a strcmp).

ec6056e3ab glib-mkenums: allow optional 'since' tag
The glib-mkenums program allows generating code to handle enums/flags
with very different purposes. One of its purposes could be generating
per-enum/flag methods to be exposed in a library API, and while doing
that, it would be nice to have a way to specify in which API version
the enum/flag was introduced, so that the same version could be shown
in the generated API methods.

E.g. From the following code:

    /**
     * QmiWmsMessageProtocol:
     * @QMI_WMS_MESSAGE_PROTOCOL_CDMA: CDMA.
     * @QMI_WMS_MESSAGE_PROTOCOL_WCDMA: WCDMA.
     *
     * Type of message protocol.
     *
     * Since: 1.0
     */
    typedef enum { /*< since=1.0 >*/
        QMI_WMS_MESSAGE_PROTOCOL_CDMA  = 0x00,
        QMI_WMS_MESSAGE_PROTOCOL_WCDMA = 0x01
    } QmiWmsMessageProtocol;

The template would allow us to generate a method documented like this,
including the Since tag with the value given in the mkenums 'since' tag.

    /**
     * qmi_wms_message_protocol_get_string:
     * @val: a QmiWmsMessageProtocol.
     *
     * Gets the nickname string for the #QmiWmsMessageProtocol specified at @val.
     *
     * Returns: (transfer none): a string with the nickname, or %NULL if not found. Do not free the returned value.
     * Since: 1.0
     */
    const gchar *qmi_wms_message_protocol_get_string (QmiWmsMessageProtocol val);

13d1697b67 gobject: Add g_{param_spec,signal}_is_valid_name() functions
Making this validation code public allows projects to validate a
GParamSpec name before creating it. While hard-coded GParamSpec don't
need this, we can't afford crashing the main program for dynamically
generated GParamSpec from user-created data.

In such case, we will need to validate the param names and return errors
instead of trying to create a GParamSpec with invalid names.

Includes modifications from Philip Withnall and Emmanuele Bassi to
rearrange the new function addition and split it into one function for
GParamSpecs and one for GSignals.
