LC is also necessary, and it is not granted by default to anyone but
System and Administrator, so tests had to be done negatively

Tombstone reanimation requries some special handling which is going
to affect several modules. Most notably:
- a bit different access checks in acl.c
- restore certain attributes during modify requests in samldb.c
Control added also to schema_samba4.ldif by Andrew Bartlett
hence the "pair programmed with" tag.

It turns out that the effective credits_requested is always at least 1,
even if the client sends credits_requested == 0.
This means the client is not able to reduce the amount of credits
itself.
Without this fix a client (e.g. Windows7) would reach the case
where it has been granted all credits it asked for.
When copying a large file with a lot of parallel requests,
all these requests have credits_requested == 0.
This means the amount of granted credits where reduced by each
request and only when the granted credits reached 0,
the server granted one credit to allow the client to go on.
The client might require more than one credit ([MS-SMB2] says
Windows clients require at least 4 credits) and freezes
with just 1 credit.

Drops the iptables() and ip6tables() functions and, hence, the
hardcoding of paths /sbin/iptables and /sbin/ip6tables. The latter
avoids problems on openSUSE where (for example) /usr/sbin/iptables is
used instead.
This means that locking around ip*tables commands is only done when
iptables_wrapper is called directly. This is fine because the only
conflict is when "releaseip" or "takeip"/"updateip" events are run in
parallel. The other uses in 11.natgw and 70.iscsi are in events where
there will be no collisions.
Making 11.natgw support IPv6 is unnecessary. Just put a static IPv6
address on each interface - they're plentiful.
