* The first line of Python script could be executed twice when the source
encoding (not equal to 'utf-8') was specified on the second line.

* Now the source encoding declaration on the second line isn't effective if
the first line contains anything except a comment.

* As a consequence, 'python -x' works now again with files with the source
encoding declarations specified on the second file, and can be used again
to make Python batch files on Windows.

* The tokenize module now ignore the source encoding declaration on the second
line if the first line contains anything except a comment.

* IDLE now ignores the source encoding declaration on the second line if the
first line contains anything except a comment.

* 2to3 and the findnocoding.py script now ignore the source encoding
declaration on the second line if the first line contains anything except
a comment.

This code was an artifact of issuing a DeprecationWarning for the lack
of loader.exec_module().  However, we have deferred such warnings to
later Python versions.

already cached the zip's table of contents we detect this and recover
rather than read bad data from the .zip (causing odd import errors).

Thanks to David Watson for taking an initial stab at a solution.

old methods now provide implementations when PEP 451 APIs are present.

This should help with backwards-compatibility with code which has not
been updated to work with PEP 451.
