Update to reflect using "" as the default value for the second parameter
to the get() method.

setdefault() the empty string.  In setdefault(), use + to join the value
to create the entry for the headers attribute so that TypeError is raised
if the value is of the wrong type.

When regrtest.py finds an attribute "test_main" in a test it imports,
regrtest runs the test's test_main after the import.  test_threaded_import
needs this else the cross-thread import lock prevents it from making
progress.  Other tests can use this hack too, but I doubt it will ever be
popular.

This should be faster.

This means:

(1) "for line in file:" won't work if the xreadlines module can't be
    imported.

(2) The body of "for line in file:" shouldn't use the file directly;
    the effects (e.g. of file.readline(), file.seek() or even
    file.tell()) would be undefined because of the buffering that goes
    on in the xreadlines module.

ought to be faster.

UTF-16 codec will now interpret and remove a *leading* BOM mark. Sub-
sequent BOM characters are no longer interpreted and removed.
UTF-16-LE and -BE pass through all BOM mark characters.

These changes should get the UTF-16 codec more in line with what
the Unicode FAQ recommends w/r to BOM marks.

Mark Hammond claimed that the iterized filter() forgot to decref the
iterator upon return.  He was right!

but doing so raised EOFError.  This makes it work as advertised and
converts to string methods where reasonable.
