Don't use CTRL_TYPE_UNKNOWN as value_string[] terminator, use an explicit, more
obvious { 0, NULL } termination. Set an explicit string for CTRL_TYPE_UNKNOWN.
No other value_string[]s to date have such a "hidden" terminator.
BTW, a { 0, "string" } item is not a terminator, only { 0, NULL } is, so we can
set a string for CTRL_TYPE_UNKNOWN == 0.
Also, having a string value for CTRL_TYPE_UNKNOWN is not harmful because all
code paths explicitly check for the CTRL_TYPE_*s that are valid.
Adjust the test expectation.
From the ctrl_type_vals enum, remove the = 0, because it is implicitly 0
anyway.
One motivation to press this fixup: I am trying to add a script that checks
whether all value_string[]s are terminated to our jenkins jobs, and to find
that this one is terminated, it would need to interpret the CTRL_TYPE_UNKNOWN
constant, which would make things far more complex. At this point, all of the
value_string[]s have an explicit termination, and I would like to enforce this
from now on -- for readable code and to not spend more time on the validator.
The patch adding ctrl_type_vals (Icd4e96dd9f00876cb70b43cfcf42ab4f10311b28) was
accepted by another reviewer before I could reconfirm my -1, so this is a fixup
to enable the termination checking script patches.

The 'strtok_r' function requires passing a NULL as the first parameter
on subsequent calls in order to ensure the code picks up where it left
off on a previous call. However, Coverity doesn't quite realize this
and points out that if a NULL was passed in as the third argument it
would result in a possible NULL deref because the strtok_r function will
assign the third argument to the first in the call is NULL.

We check that the amount of commands is not more than
we have but we don't check it the other way. It appears
that the vector is allowed to be bigger than the amount
of commands. So we match a prefix of a longer command
depending on the installation order.
Sometimes a control interface command cannot be processed
and responded immediately, but we need to process it asynchronously.
In order to support this, we introduce the 'ctrl_cmd_def', which
represents such a deferred command. It is created by the service
implementing the command using ctrl_cmd_def_make(), and a response is
later sent using ctrl_cmd_def_send().
ctrl_cmd_def_is_zombie() must be called to handle the case where
the control connection has disconnected/died between receiving the
command and sending the response.
