416df5d7c2 Skip parsing date after failing to parse the date
When file_use_mail_timestamp or utime_from_header are enabled,
OfflineIMAP tries to parse the Date header in the email.  If the header
is present but invalid -- it doesn't contain a valid date -- this will
cause email.message to raise an exception.  This is all fine.  However
when handling that exception, OfflineIMAP can't try to extract the date
again: it's clearly invalid, and raising the same exception a second
time while handling the first exception just causes the entire sync to
fail.

To avoid that happening, don't try to provide the invalid date string in
the error message.  Instead, just give the user the UID of the email
that triggered the exception, and the exception text.

Ideally we'd instead fix the code to actually extract the header value
and provide it in the error message, but Python's email.message module
doesn't provide an easy way to get the raw text of the Date header from
an EmailMessage object; it's possible using private variables like
EmailMessage._headers, or by parsing the email using a custom
email.policy.EmailPolicy object that disables the module's attempts to
coerce the header value to a DateTime.  However, a user should be able
to get the problematic Date header from the message directly anyway, so
it's not worth adding all that complexity for something that should be
rare and provides little value.

Fixes #134

correcting broken multipart boundaries or raising an error if as_bytes()
fails.  Related python bug submitted: https://bugs.python.org/issue43818

1d2478bcb6 Series of *UNTESTED* changes that should move the internal structure of
a message from a string to an email object that is part of the built-in
email library.  The allows for emails to be processed as bytes and
re-encoded properly if they are not UTF-8 or ascii encoded.  Currently
these changes cover the Base, IMAP, and Maildir classes but not the
specialized GMAIL class yet.

a311faf183 IMAP search now works fine
This patch converts the search results from bytes to strings

I add a bit comment about it here:

    In Py2, with IMAP, imaplib2 returned a list of one element string.
      ['1, 2, 3, ...'] -> in Py3 is [b'1 2 3,...']
    In Py2, with Davmail, imaplib2 returned a list of strings.
      ['1', '2', '3', ...] -> in Py3 should be [b'1', b'2', b'3',...]

    In my tests with Py3, I get a list with one element: [b'1 2 3 ...']
    Then I convert the values to string and I get ['1 2 3 ...']

    With Davmail, it should be [b'1', b'2', b'3',...]
    When I convert the values to string, I get ['1', '2', '3',...]

442c88d838 imaplib expect bytes in the append
imaplib2 is doing this code for strings:

        if isinstance(message, str):
            message = bytes(message, 'ASCII')

But our message is already encoded using 'utf-8'.
Then, we can set the message as bytes, encoded using 'utf-8'
in offlineimap and imaplib2 won't change our message.

This patch solves this problem:

This completely aborted offlineimap3, blocking further mail reception.

Instead, use the 'replace' error strategy in Python:

    Replace with a suitable replacement character; Python will use the
    official U+FFFD REPLACEMENT CHARACTER for the built-in Unicode codecs on
    decoding and ‘?’ on encoding.

423785725b IMAP.py: server responses are in bytes, not string
Following error is seen when parsing server responses for sent mail:

2020-10-12 08:19:11 WARNING: Can't parse FETCH response, we awaited string: b' UID 26855)'
2020-10-12 08:19:11 WARNING: savemessage: Searching mails for new Message-ID failed. Could not determine new UID on Sent.

The comparison with 'type("")' means comparing with 'string' type in Python
3, but the left-hand side is a bytes object.

In case a tuple was received (first case in the code), the input is already
decoded from bytes to strings, but in case a single input was received it
was not.

Note that the comparison with 'type("")' is a bit odd, a more logical way
seems to be:
    if isinstance(item, bytes)
