Implement completely new format for compiled package descriptions.
Old format was code to build the packages and load files into them.

interpreted at run time to provide the same functionality.

The purpose of this change is to support uninstallation and

general enough for this purpose.

Implement primitive to allow linking variables that have different
names.  (Previously, linked variables were required to have the same
name.)  This requires a major redesign of the cache data structures,
and since the garbage collector knows about these structures, all of
the garbage-collector files are affected too.  The new data structures

uses one word less than previously, while a cache with references uses
three words more than previously (independent of the number of
references).
