Previously mailbox was copying a list of attributes from one message object to
another in order to "copy the message data". This means that any time new
attributes were added to email.message.Message, mailbox broke. Now instead it
copies all attributes from the source object to the target object, skipping
any mailbox-object-specific attributes to produce the same clean initial
state it was previously getting by copying only the "known" attributes.

In Python2, if a unicode string was assigned as the value of a header,
email would automatically CTE encode it using the UTF8 charset.
This capability was lost in the Python3 translation, and this patch
restores it.
Patch by Ali Ikinci, assisted by R. David Murray.
I also added a fix for the mailbox test that was depending (with a comment
that it was a bad idea to so depend) on non-ASCII causing message_from_string
to raise an error. It now uses support.patch to induce an error during
message serialization.

Remove a sleep to fix transient test failures. Use skewfactor of -3 to
make it work on systems that have 1 second precision for time.time().

We don't need to create a temporary buffered binary or text file object just to
create an empty file.
Replace also os.fdopen(handle).close() by os.close(handle).
All of the other methods in mailbox that create message objects take care to
close the file descriptors they use, so it seems to make sense to have
__getitem__ do so as well.

'latin-1' and 'utf-8'.
These are optimized in the Python Unicode implementation
to result in more direct processing, bypassing the codec
registry.
