Get rid of Boolean "flags" that don't have any bit set.
And tweak the Pidl generator for Wireshark not to generate "flags" like
that.
(The generator also does field name and true/false strings' case
differently, so I didn't use it to regenerate the dissectors; that needs
to be looked at.)

cmdline:burn: always return true if burnt
Before we have been trying to cram three cases into a boolean return
value:
* cmdline had secrets, we burnt them -> true
* cmdline had no secrets, all good -> false
* cmdline has NULL string, WTF! emergency! -> false
This return value is only used by Python which wants to know whether to
go to the trouble of replacing the command line. If samba_cmdline_burn()
returns false, no action is taken.
If samba_cmdline_burn() burns a password and then hits a NULL, it would
be better not to do nothing. It would be better to crash. And that is
what Python will end up doing, by some talloc returning NULL triggering
a MemoryError.
What about the case like {"--foo", NULL, "-Ua%b"} where the secret comes
after the NULL? That will still be ignored by Python, as it is by all C
tools, but we are hoping that can't happen anyway.

cmdline:burn: do not retain false memories
If argv contains a secret option without an '=' (or in the case of
"-U", the username is separated by space), we will get to the
`if (strlen(p) == ulen) { continue; }` without resetting the found
and is_user variables. This *sometimes* has the right effect, because
the next string in argv ought to contain the secret.
But in a case like {"--password", "1234567890"}, where the secret
string is the same length as the option, we *again* take that branch
and the password is not redacted, though the argument after it will be
unless it is also of the same length.
If we always set the flags at the start we avoid this. This makes
things worse in the short term for secrets that are not the same
length as their options, but we'll get to that in another commit soon.

Fix starvation of pending writes in CTDB queues
CTDB uses a queue to receive requests and send answers. It works
asynchronously using the tevent framework. However there was an issue
that gave priority to the receiving side so, when a request was
processed and the answer posted to the queue, if another incoming
request arrived, it was served before sending the previous answer.
This scenario could repeat for long periods of time if the frequency of
incoming requests was high enough.
Eventually, a small time gap between incoming request gave a chance to
process the pending output queue, sending many answers in a burst.
This patch makes sure that both queues (input and output) are processed
if the event contains the appropriate flag.

smbd: Fix crossing automounter mount points
We get ENOENT on /proc/self/fd/<fdnum> when we try to turn the
mountpoint's O_PATH handle into a real one. This does not trigger a
mount attempt, you have to use name-based calls.
This is not the real fix, because if the autofs mount triggers, the
inode number will change. For directories this is not a huge problem
as we don't touch the share mode database before we open the "real"
fd. We would only violate potential share modes with other pure
READ_ATTRIBUTES (i.e. stat-) opens that came before the mount
trigger.
As I don't think share modes on directories are really relevant, I
think we can live with this "fix". Once we do directory leases this
will potentially change.
As a quick remedy we could use our defer_open() mechanism that starts
path processing from scratch. But as long as this seems not really
required, we should not add users of this really bad way of going back
to square 1.
The "real" fix would be to go back to the point where we open the last
component with openat(). In the retry round we need to do this without
O_PATH to trigger the mount and only then do the initial fstat.
Right now I don't see an easy way to properly test this
behaviour. Intercepting with vfs_error_inject is certainly possible,
but nailing the exact call would clutter the main code path. So I have
just tested this manually.

rpc.statd is single-threaded and runs its HA callout synchronously. If
it is too slow then latency accumulates and rpc.statd's backlog grows.
Running a pair of add-client/del-client events with the current code
averages ~0.030s in my test environment. This mean that 1000 clients
reclaiming locks after failover can easily cause 10s of latency. This
could cause rpc.statd to become unresponsive, resulting in a time out
for an rpcinfo-based health check of the status service.
Split the add-client/del-client events out to a standalone
statd_callout executable, written in C, to be used as the HA callout
for rpc.statd. All other functions move to statd_callout_helper.
Now, running a pair of add-client/del-client events in my test
environment averages only ~0.002s. This seems less likely to cause
latency problems.
The standalone statd_callout executable needs to read a configuration
file, which is generated by statd_callout_helper from the "startup"
event. It also needs access to a list of currently assigned public
IPs.
For backward compatibility, during installation a symlink is created
from $CTDB_BASE/statd-callout to the new statd_callout, which is
installed in the helper directory.
Testing this as part of the eventscript unit tests starts to become
even more of a hack than it used to be. However, the dependency on
stubs and the corresponding setup of fake state makes it hard to move
this elsewhere.
