This patch adds an extern "C" guard in libqrtr.h, so that it can be
included in both C and C++ projects.

This include provides err, errx, etc. but it looks like all
error logging in qmi.c is done with fprintf, so there's no
reason to include it.

Definition of AF_QIPCRTR was introduced in glibc in the following
commit and is only available since glibc 2.25 or later.

This patch modifies libqrtr.h to define AF_QIPCRTR if it isn't defined
in libc header, which allows compilation of libqrtr on a system with an
older version of glibc. The compiled libqrtr can still be used on a
system with kernel 4.7 or later with the QIPCRTR support.

The QMI functions can be used to deal with QMI-encoded data in
qrtr_packet objects. The structure-description is the same element-info
arrays as is used in the upstream Linux kernel.

The qrtr_decode() takes a buffer of data and returns a decoded qrtr
packet object, this will either contain control data or a reference to
the message data.

The uapi qrtr.h is extended with additional types and constants. Drop
the local qrtr.h to use the one from linux-headers and extend it
conditionally while we're waiting for the updated file.

When sending a new_server message to the qrtr-ns the node and port in
the packet is ignored (to not allow clients spoofing the information),
so there's no reason to have this artificial check in the
qrtr_new_server() implementation either.
The socket will be bound to a port automatically when the new_server
message is sent out.

There's no reason to require that the socket to be bound to a specific
port in order to register a lookup, the transmission of the lookup
request will autobind the socket to a port for us.
Also drop the node and port from the payload, as qrtr-ns will register
the lookup on the source sq, rather than the passed port.

Fix up the handling of endian translation and add support for decoding
new and del server messages.

The two added functions can be used by an application to check if a
sockaddr is from the control port and for parsing the control messages
that is passed to registered clients.

Now that we have moved all operations to the control socket we can
remove the ns handler. The query function in the library is racy, as
there might be non-response messages in our incoming buffer when we
start reading, so this is dropped too - rather than just being
translated to the new interface.

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.

Replace the implementation of the two library functions with calls to
the new APIs, so that we can remove the server-side implementation of
the previous messages.

Add a new set of operations to libqrtr for sending registration events
to the control service, rather than using the nameservice port.

Extract the libqrtr source and header file to a separate directory,
making it more convinient to include the header file from other
projects.
