[issue15160] Add support for MIME header parsing to the new provisional email policies

[R. David Murray]

New submission from R. David Murray <rdmurray at bitdance.com>:

I've been working on this steadily for a while.  I think it is now all working correctly.  At least, it passes all the same tests that the existing RFC mime header parser passes, plus a bunch of additional ones.

There are a couple of commented out tests where there are issues with the folding.  The folding doesn't normally get invoked for headers parsed from source, and the cases are marginal anyway (headers with invalid binary data) so I'm not worried about them, but will fix them after the beta.

There are things that can be done to make this API even more convenient, but I think this is a solid foundation worth having.  And the parser is a full RFC parser, so it handles cases that the current parser doesn't.  (There are also probably cases where it fails when the current parser doesn't, but I haven't found them yet ;)
