Refactored glue code generation for APIs requiring run-time lookup of

individual function pointers into generic ProcAddressEmitter. Removed
all OpenGL-specific routines and names from this emitter. The new
ProcAddressConfiguration is more generic than the GLConfiguration and
supports mostly-arbitrary mappings from function names to function
pointer typedefs via the new ProcAddressNameExpr directive. Refactored
GLEmitter into thin layer on top of this ProcAddressEmitter providing
only ignoring of extensions and checking for buffer object variants of
functions. Made GLConfiguration a stand-alone class. Deleted
ContextVariableName directive in favor of more generic
GetProcAddressTableExpr command. Moved resetting of generated
ProcAddressTables into GlueGen runtime class ProcAddressHelper; user
provides the dynamic lookup function (dlsym, etc.) through new
DynamicLookupHelper interface. Fixed bug in generation of Java
epilogues for routines returning primitive values. Fixed bugs in
AccessControl directive, in particular when generating interfaces.
Made small changes to autogenerated comments for routines called
through function pointers.

These changes do not impact the public API of JOGL -- this has been
verified by examining diffs between the current and new autogenerated
code. They do make the GlueGen tool more generic and allow it to be
easily applied to the task of autogenerating the JOAL API and
implementation as well. Also verified by running JOGL demos and JOAL
demos in new JOAL workspace.
