Moved remaining portions of fixed function emulation out of core JOGL

public and implementation packages and into
com.sun.opengl.util.glsl.fixed.* and other subpackages of
com.sun.opengl.util. Renamed javax.media.opengl.sub.GLObject to
javax.media.opengl.GLBase. Moved interfaces in
javax.media.opengl.sub.fixed to javax.media.opengl.fixedfunc and
changed naming convention. Moved all classes in
javax.media.opengl.util to com.sun.opengl.util. Moved
com.sun.opengl.impl.packrect to com.sun.opengl.util.packrect. Renamed
InternalBufferUtils to InternalBufferUtil to match naming convention
and copied in needed routines for GLU and other classes. Fixed build
breakage when specifying rootrel.build property; reintroduced
build-temp directory. Updated demos.

+/** Represents a rectangular region on the backing store. The edges of
+    the rectangle are the infinitely thin region between adjacent
+    pixels on the screen. The origin of the rectangle is its
+    upper-left corner. It is inclusive of the pixels on the top and
+    left edges and exclusive of the pixels on the bottom and right
+    edges. For example, a rect at position (0, 0) and of size (1, 1)
+    would include only the pixel at (0, 0). <P>

+    no sense in the context of the packer, which deals only with
+    positively sized regions. <P>
