Sometimes an MTA may just send back the headers of the original message
rather than the entire original message. Such an email will have a
`text/rfc822-headers` part which will be the complete headers of the
original message.

Without this patch, osTicket will create a new ticket for the bounce message
rather than attaching the new internal note to the existing ticket.

Consider closed date to determine ticket's last activity date. The net effect is closed tickets queue will be sorted by closed date.

This patch uses a 'StringView' to create a string which is a window of
another string. The __toString() method is employed to fetch a lazy copy of
the window which can be usually immediately discarded. This is optimal for
one-time-use string copies like what is used in the mail parsing.

Previously, the new internal note alert was only sent to the assigned staff
member, if any were assigned.

Previously, there was a bug in the ORM where magic properties would need to
be declared in the model class.

tnef: Fix major issue iterating over attar streams

Reviewed-By: Peter Rotich <peter@osticket.com>

The original logic would read the count of attributes in the stream and then
read the first attribute in the constructor of TnefAttributeStreamReader.
Then the iterator interface would call ::rewind() before iterating to the
first item. rewind() set the @pos attribute to zero, which would cause the
attribute count (4-byte int) to be interpreted incorrectly as part of the
first attribute.

The new logic sets the position at 4 after rewind()ing, and does not read
the first attribute twice. It also properly detects the end of the attribute
stream by the number of attributes advertised as the first four bytes of the
stream (read into the @count attribute initially).

On validation errors, `$faq` will be set to something non-null, like
`false`, but will not be an instance of a Faq article.

For PHP installations that have `mbstring.func_overload` enabled (set to a
value including `2`), the `strlen` function will be overloaded to use the
`mb_strlen` equivalent. Problematically, the internal encoding of `UTF-8`
will be applied to all file content, which will count UTF-8 characters
rather than bytes. This will cause the data to be saved correctly; however,
the `size` recorded in the %file table will be recorded incorrectly.

This patch allows the backend to report the size of the contents saved with
the request and provides a failsafe mechanism which will use the mbstring
equivalent if available, and the mbstring version is coded to use the `8bit`
as the encoding which will prevent reading characters.
