Currently, offsetof produces an unsigned long, while qmi_elem_info's
offset member is a uint32_t. Since this is not the same type on all
platforms, this change uses a size_t for both. stddef.h is also
included for the standard offsetof definition, which also produces a
size_t.
This change also makes similar modifications to list.h.
With the introduction of the in-kernel nameserver launching the user
space qrtr-ns will fail, but typically other services depends on its
presence. As such, go dormant instead of failing when noticed that the
name service is already present.

Removing entries from an open addressed hash table creates holes in the
collision chains, preventing previous colliding entries to be found. By
inserting tombstones, rather than clearing deleted entries makes it
possible to distinguish the end of a chain from a hole.

The dprintf macro shadows a real libc symbol which is called
differently, so we should change it to something else (in this
case LOGD) and change it to use the libqrtr logging facilities.
This also means we should add a minimum priority to the logging
library so we don't log DEBUG-level messages by default.
Additionally there were some warn/warnx calls left over that
have been changed to PLOGW/LOGW respectively.
The DIAG service has its own encoding for the instance number which
is unrelated to the version. This means that the information we
show to the user in the version and instance columns of the table is
parsed incorrectly and often useless. Instead, treat the instance
number as special if the service is a DIAG service and print out a
more meaningful interpretation.

waiter_wait_timeout() doesn't initialize the 'callback' and 'updated'
fields of the waiter_ticket struct. The 'updated' field may contain some
garbage value, which is later read in waiter_ticket_check().

This function in qrtr-ns was largely copied from the main

The __progname symbol is a GNU extension and thus not portable,
but basename (from libgen.h) and argv[0] can be used portably
instead.
(qrtr-lookup already used argv[0] but did not apply basename, so
do that for consisntency.)

When a server is disappearing, either from a DEL_SERVER, BYE or
DEL_CLIENT message the same messages needs to be sent; to local
observers and through broadcasts to remote nodes.
So move the logic from the DEL_SERVER command handler to server_del, in
order to invoke this regardless of reason for the server's
disappearance.

Now that we have moved all operations to the control socket we can

there might be non-response messages in our incoming buffer when we

Introduce a subscription based lookup model, in order for a client to be
able to listen to a future spawning service. The client can register any
number of queries with the ns and the ns will post lookup-results as
services are registred.
As a special case the list of lookup-results that is sent out as a
result of the registration of a new lookup will be finished by an empty
lookup response, allowing tools like qrtr-lookup to terminate as the
entire list of currently registed services is received.
