Added NativeLibrary helper class to com.sun.gluegen.runtime package,

principally to generally solve the problem of downloading dependent
libraries of GlueGen-generated native code, as in the case of JOAL and
OpenAL reported recently by Shawn Kendall on JOAL forums.
Autogenerated Java and native code associated with this new
NativeLibrary helper class is currently checked in to the GlueGen
workspace to make it easier to build across multiple platforms; it can
be regenerated by running the generate.nativelibrary.sources Ant
target in the GlueGen workspace. Building of the native code in the
GlueGen workspace is currently disabled by default and can be enabled
by specifying -Dbuild.native=1 on the ant command line. Use of the new
NativeLibrary class in JOAL is currently disabled by default and can
be enabled by specifying -Djoal.use.gluegen=1 to applications using
JOAL. New functionality has been lightly tested with JOAL on Windows
and appears to be working. More testing, including build and Java Web
Start deployment testing, to follow on other platforms.
