Affected functions would then dereference a NULL pointer and the test

When executing a shell script code "foo | bar", if "bar" terminates early,
then "foo" can get I/O error when writing to stdout.
The tdbtool stub did not wait to read anything from stdin when it is
expected to. This would cause tests to fail randomly under load when
tdbtool process exited early.
Similarly, debug function read from stdin only under certain conditions
(higher debug and when not reading from tty). Otherwise, exited early.
Thanks to Andrew Bartlett for noticing the problem and Catalyst Cloud
(http://catalyst.net.nz/cloud) for providing resources to test fixes.

Although much of the test infrastructure in recent commits is actually
targeted for "reloadnodes", it is worthwhile adding some tests for
"reloadips" and "recover". This allows most of the test
infrastructure to be tried out against known good code.

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.

This is a gawk extension and can't be used reliably if just running
"awk". It is simple enough to switch to using the standard sub() and
gsub() functions.
The alternative is to switch to explicitly running "gawk". However,
although the eventscripts aren't exactly portable, it is probably
better to move closer to portability than further away.

These tests simulate a dead node rather than a CTDB failure, so drop

To cope with a CTDB failure a watchdog would be needed to ensure that

If CTDB_USE_IPV6 is set then use IPv6 addresses for nodes and public
IPs. This can be useful for some simple tests. However, the node
address actually needs to be on lo so that ctdbd can bind to the port
on that address, so they actually need to be added as root before
running tests, like this:
for i in $(seq 1 10) ; do ip addr add "fc00:10::${i}/64" dev lo ; done
IPv4 127.0.0.0/8 addresses are somehow magic and only one needs to be
on lo so that many can be bound to.
Also change the IPv4 node addresses to be (slightly) more exotic.
For both IPv4 and IPv6, choose addresses that are compatible with
socket wrapper.

There are parentheses missing that stop the default pattern from
matching commands with trailing garbage (e.g. "exportfs.orig").
A careful check of POSIX (and running GNU sed with --posix) suggests
that "\|" isn't a supported way of specifying alternation in a regular
expression. Therefore, it is clearer to switch to extended regular
expressions so that this has a chance of being portable (even though
the point is to print /proc/<pid>/stack, which only works on Linux).
