This change is related to patch called
"net: Adapt to new behavior of net_buf_frag_add"
This version removes extra net_nbuf_unref() from
the code. The unref was done because net_buf_frag_del()
did not remove the double ref from the list element.
Because of the other patch, the list does not have
double ref any more, so we need to remove the extra
unref in couple of extra places.

net_buf_frag_add takes the ownership of the reference passed to it so it
is no longer needed to unref when deleting fragments.

When an incoming TCP connection is accepted, a net_context for the
client is allocated. However, some steps prior to calling the
user-defined accept callback can fail, without freeing the
newly-allocated client context.

This keeps the semantics of the low-level network stack API closer to
the BSD sockets API. Prior to this change, listen() primitive was a
no-op, and accept() would change the connection state to LISTEN; this
changes the functions so that calling listen() is required before
calling accept().

RFC2131 requires that a client must choose XIDs in order to minimize
the chance of collision with another client. Selection of a random
XID at boot is a valid approach. Adjust the XID representation from
array of bytes to the more convenient uint32_t representation,
initialize the XID to a random number and increment for each request.
Refactor the dhcp test case to generate response messages with the XID
from the received message.

This commit modifies the conf and Makefile files of the DNS client
application.
Inside the Makefile, the CONF_FILE variable is updated to include
the BOARD name, therefore prj_'board_name'.conf is used from now on
to refer to the conf file. The right conf file is selected by passing
BOARD='board_name' to make.
Configuration variables at the conf files are also homogenized.

Move the IN_USE clear in net_tcp_release() to the END of the function
after the destruction is complete so someone else doesn't allocate it
while we're still cleaning it up.
Also, operations on the IN_USE flag need to be atomic for correctness.
Stick an irq_lock() around them.

Big chunks of this struct were essentially unused:
+ The prev_state field was stored at state change but never inspected.
+ The send_wnd, send_max_wnd, send_cwnd, send_pcount and
send_ss_threshold fields were simply unused.
+ The recv_scale field was never initialized to anything but zero,
remove the support. Windows greater than 64k seem very unlikely to
be useful to Zephyr anyway; if we actually want window scaling (in
either direction -- there are large memory costs!) it should
probably be optional via Kconfig. We surely don't want to carry
this for all builds.
+ The buf_max_len field was hard-coded static, replace with a #define
+ Double-memset of the ack_timer field in initialization
