Add a GObject-based wrapper library for libudev

introspection support.

+ * SECTION:gudevclient
+ * @short_description: Query devices and listen to uevents
+ *
+ * #GUdevClient is used to query information about devices on a Linux
+ * system from the Linux kernel and the udev device
+ * manager.
+ *
+ * Device information is retrieved from the kernel (through the
+ * <literal>sysfs</literal> filesystem) and the udev daemon (through a
+ * <literal>tmpfs</literal> filesystem) and presented through
+ * #GUdevDevice objects. This means that no blocking IO ever happens
+ * (in both cases, we are essentially just reading data from kernel
+ * memory) and as such there are no asynchronous versions of the
+ * provided methods.
+ *
+ * To get information about a device, use
+ * g_udev_client_query_by_subsystem(),
+ * g_udev_client_query_by_device_number(),
+ * g_udev_client_query_by_device_file(),
+ * g_udev_client_query_by_sysfs_path() or
+ * g_udev_client_query_by_subsystem_and_name().
+ *
+ * To listen to uevents, connect to the #GUdevClient::uevent signal.

+ * SECTION:gudevdevice
+ * @short_description: Get information about a device
+ *
+ * The #GUdevDevice class is used to get information about a specific
+ * device. Note that you cannot instantiate a #GUdevDevice object
+ * yourself. Instead you must use #GUdevClient to obtain #GUdevDevice
+ * objects.
+ *
+ * To get basic information about a device, use
+ * g_udev_device_get_subsystem(), g_udev_device_get_devtype(),
+ * g_udev_device_get_name(), g_udev_device_get_number(),
+ * g_udev_device_get_sysfs_path(), g_udev_device_get_driver(),
+ * g_udev_device_get_action(), g_udev_device_get_seqnum(),
+ * g_udev_device_get_device_type(), g_udev_device_get_device_number(),
+ * g_udev_device_get_device_file(),
+ * g_udev_device_get_device_file_symlinks().
+ *
+ * To navigate the device tree, use g_udev_device_get_parent() and
+ * g_udev_device_get_parent_with_subsystem().
+ *
+ * To access udev properties for the device, use
+ * g_udev_device_get_property_keys(),
+ * g_udev_device_has_property(),
+ * g_udev_device_get_property(),
+ * g_udev_device_get_property_as_int(),
+ * g_udev_device_get_property_as_uint64(),
+ * g_udev_device_get_property_as_double(),
+ * g_udev_device_get_property_as_boolean() and
+ * g_udev_device_get_property_as_strv().
+ *
+ * To access sysfs attributes for the device, use
+ * g_udev_device_get_sysfs_attr(),
+ * g_udev_device_get_sysfs_attr_as_int(),
+ * g_udev_device_get_sysfs_attr_as_uint64(),
+ * g_udev_device_get_sysfs_attr_as_double(),
+ * g_udev_device_get_sysfs_attr_as_boolean() and
+ * g_udev_device_get_sysfs_attr_as_strv().
+ *
+ * Note that all getters on #GUdevDevice are non-reffing – returned
+ * values are owned by the object, should not be freed and are only
+ * valid as long as the object is alive.
+ *
+ * By design, #GUdevDevice will not react to changes for a device – it
+ * only contains a snapshot of information when the #GUdevDevice
+ * object was created. To work with changes, you typically connect to
+ * the #GUdevClient::uevent signal on a #GUdevClient and get a new
+ * #GUdevDevice whenever an event happens.
