This is based on the auto_delete flag on mail.mail
and the assumption that mail.mail records created
without a parent message will be deleted as a whole,
including the parent message and its attachments.
This is contrasted with mail.mail records created
for notifications regarding a mail.message, and therefore
created with an existing `mail_message_id` parent.
For this last case the parent must not be deleted
along with the child mail.mail, as it exists on its own.

Body of send emails is mail_mail.body_html, not body anymore.
Signature adding is back to mail_followers.notify().
Subject adding is still done just before sending.
Updated mail_mail view. mail.compose.message: body_text inside <pre>.
[TESTS] mail: added tests for message_post, updated tests for mail.message.compose to test the composer only.

Removed body_html and content_subtype fields. We now entirely
rely on the body field, that holds sanitized HTML.
Added a user_signature field from email_template. mail_mail.send()
is now responsible of adding the signature on emails.
mail_notification.notify() sets the user_signature flag on
emails send for notifciations.
mail_mail.send() is responsible of adding a default subject
on emails send if there is no subject on the mail.message,
and res_id and model are set.
purchase_requisition: removed an override of mail.message
schedule_with_attach.
