This imports the change made in commit b33a1b7 to scapy-com repository
by Timo Juhani Lindfors <timo.lindfors@iki.fi>.

This fixes issue #566:

Before:

    >>> DNSRR(str(DNSRR(type="PTR", rdata="secdev.org"))).rdata
    WARNING: DNS RR prematured end (ofs=8550, len=8)
    ''

After:

    >>> DNSRR(str(DNSRR(type="PTR", rdata="secdev.org"))).rdata
    'secdev.org.'

This is useful when a field value content is tampered without the
value itself being changed (this can happen with values of type list
and Packet, for example).

When iterating over `Packet` instances, `.raw_packet_cache` attribute
was not used, causing bugs similar to the one detailed in issue #913
to appear when packets sniffed or built from strings representations
were used with `wrpcap()`, `send`(`p`?), `sr`(`p`?), etc.

This commit essentially copies the `.raw_packet_cache` attribute in
`.clone_with()` method.
