[issue21986] Idle: disable pickleability of user code objects

[Terry J. Reedy]

Terry J. Reedy added the comment:

Code objects get wrapped in 3 tuple layers before being 'pickled', so a private dispatch is the easiet solution.  Since copyreg.dispatch_table has only two items to copy, I pushed a version of the first patch.  Since private dispatch tables are new in 3.3 and not in 2.7, I withdraw the idea of patching 2.7.
