Patch: image loading fixes

[Thomas Fitzsimmons]

Hi,

This patch fixes various problems related to image loading.  It also
implements Component.imageUpdate, GtkToolkit.prepareImage and the
byte-array GtkToolkit.createImage method.

Comments?

        gnu_java_awt_peer_gtk_GdkPixbufDecoder.c
        * Makefile.in: Regenerate.
        * gnu/java/awt/image/ImageDecoder.java (ImageDecoder(byte[],int,int)):
        New constructor.
        (startProduction): Create ByteArrayInputStream when url and filename
are
        null.
        (produce): Declare stream parameter as InputStream.
        * gnu/java/awt/image/XBMDecoder.java (produce): Declare stream
parameter
        as InputStream.
        * gnu/java/awt/peer/gtk/GdkPixbufDecoder.java
        (GdkPixbufDecoder(byte[],int,int)): New constructor.
        (produce): Declare stream parameter as InputStream.
        * gnu/java/awt/peer/gtk/GtkComponentPeer.java (prepareImage): Throw NPE

        source's member functions.
        (observer): New field.
        (setObserver): New method.

        new GtkImage.
        (prepareImage): Implement.
        * java/awt/Component.java (imageUpdate): Implement.
        (createImage): Call Toolkit's createImage if peer is null.
