Merged gcell-wip -r8159:8202 into trunk. This includes the following

changes:
 * gc_make_job_manager now returns a boost::shared_ptr
 * opts.program_handle is now a boost::shared_ptr
 * two new functions for getting a program handle
 * look_proc and alloc_job_desc now throw on error
 * static methods for setting and getting a single job manager
 * new exception hierarchy
 * mv gcell/src/lib/procs gcell/src/lib/wrapper
 * added libfft.  Currently inverse xform is broken
 * gcell-embedspu-libtool creates libtool complaint .ko's from SPE executables
