Beam files, module beam_lib and source code

[Robert Virding]

Adding the fix for compile.erl which I posted a few weeks back to change
the default behavior for debug_info in .beam files will not affect all
the libraries built when building the system.  However, if size is
important then replace bootstrap/lib/compiler-3.0.1/ebin/compile.beam
with a modified compile.beam.  Next time the release is built then all 
the libraries will be stripped.  This saves about 40% of the size of 
the system.
