bugzilla: add modified XMLRPC mode that uses email to send bug comments.

If Bugzilla has its email interface configured, an email can be used
to update bugs. If the From: address in the email matches a valid user
email, Bugzillas make the update as that user. So comments attached to a
bug appear under the name of the user making the change, and the user
does not receive email about the change, exactly as if they had made
the change via the web interface.

So add a modified XMLRPC mode that uses email to modify bugs. The format
of the mails is documented in the Bugzilla email_in.pl specification.
Briefly, initial non-blank lines in the message body starting
'@<field> = <value> modify bug fields. A blank line signals the end of
the command lines, and the rest of the message is used as bug comment.

Invoke the same Mercurial user to Bugzilla user email mapping
currently used in the MySQL mode.

All other processing - checking the bug numbers, checking user ids, etc.
continues to be done via XMLRPC.
