Oleg Zhurakivskyy ccb5a01fc1 net: tcp2: Refactor tcp_pkt_alloc()
In order to fix the line tracking of the TCP packet allocation
with the test protocol enabled, refactor tcp_pkt_alloc(),
so the line of the allocation can be tracked properly.

Avoid dynamic allocations and all the issues if we run out of
memory, by placing the connection endpoint directly to TCP
connection struct.

In order to properly remove struct tcp and its data, net_context
needs to be supplied as k_timer user data. Modify net_tcp_unref()
to take a net_context argument when removing, and add ifdefs
around code that after this will only be used by TCP testing
functionality.

Oleg Zhurakivskyy 851042e8e6 net: tcp2: Send TCP data to caller
Add a net_context backpointer and receiver user data to the tcp
structure. Once the desired callback and user data is set in
net_tcp_recv(), net_context_packet_received() can be called at
TCP reception in tcp_data_get(), moving the TCP data to the
recipient. IP and TCP protocol headers are sent as NULL, they
are not used by e.g. the socket code.

Oleg Zhurakivskyy c8a1b35987 net: tcp2: Implement accept() and connect()
Register the TCP connection when accept() and connect() is called.
With the connection registration net_context will have the necessary
callback pointer set up, whereby net_context can call the proper
function when receiving packets for the TCP connecton.

With the new TCP stack this callback is always the same function.
