33a6532252 librpc/dns: don't compress strings in TKEY and TSIG responses
Certain DNS clients fail TSIG record MAC validation if the TSIG record
contains compressed strings.

Windows DNS server behaviour seems to be to not send compressed names in
TKEY and TSIG records.

This patch ensures we conform to this behaviour.

d4cf68c5ae librpc/ndr: add flag LIBNDR_FLAG_NO_COMPRESSION
This flag can be used to change marshalling behaviour with regard to
compression.

Example: DNS packets make use of so called DNS name compression which
means that for identical strings in a DNS packet, the second string is
replaced with a reference (an offset) to the first.

Setting this flag requests to turns off the marshalling compression.

This will be used in the next commit to prevent name compression in DNS
TSIG records.

7c483690ac smbd: Fix file name buflen and padding in notify repsonse
The array is uint16, doubling the file name length consumes twice the space
required.

As we're hand assembling this as a series of concatinated individual data_blobs,
we must take care to ensure the correct 4 byte alignment that was
being masked by the previous doubling of the filename length.
