Added automatic strdup for RAM %s parameters. Postponed format
processing to idle time. Automatic parameters counting during
compilation. Very fast execution for up to three parameters.

14ced754f5 net: tcp: Do not send FIN when closing listening sockets
A net context in LISTENING mode waits for incoming connections, once
a new connection is established a new net context is spawned which
is responsible for handling the new connection.
Therefore when closing a LISTENING context it is not useful to send FIN
as it is never connected. Actually closing the connection would be done
by calling close on the spawned net context which is returned by the
accept call.

b0de2ee15b net: IPv6: Fix source address for mesh multicast destination
Currently there is chosen the link local address as a source address
for each multicast destination address. It is a bug for OpenThread
network where the mesh-local EID addres should be picked in this case.
This commit fixes it by distinquish the mesh local multicast among any

e548c6c5b2 net: config: rely on type rather than number of services configured
So far net config initialization code relied on number of services
needed by application. This was fine as long as all enabled
services (e.g. CONFIG_NET_IPV4=y, CONFIG_NET_IPV6=y) were selected by
project configuration as "needed" (e.g. CONFIG_NET_CONFIG_NEED_IPV4=y,
CONFIG_NET_CONFIG_NEED_IPV6=y). Problem appeared for example when both
IPv4 and IPv6 were enabled (CONFIG_NET_IPV4=y, CONFIG_NET_IPV6=y), but
only IPv6 was marked as "needed" (CONFIG_NET_CONFIG_NEED_IPV6=y). In
such situation number of required services was equal to 1. When IPv4
setup was completed, this resulted in returning from net_config_init()
function. Application code failed, because IPv6 was still not
functional.

Do not rely on number of services anymore, as it is error prone. Use
flags instead to mark which services are ready. Compare those flags with
the flags passed to net_config_init() (selected in project configuration
in most cases) to decide whether network configuration has completed
already or not.

Also introduce services_notify_ready() and services_are_ready() helper
functions to isolate implementation details from the logic.

d241c19b0f net: config: fix checking for protocols being ready
With current design there is single semaphore (called 'waiter') for
wakeing up initialization thread. This thread should then check for
number of protocols that still need to be initialized. This happens now
only when waiting on 'waiter' semaphore times out.

Do not check for k_sem_take(&waiter) return value, as all needed
information about protocols being initialized already is in 'counter'
semaphore.

0e32a84bcc net: eth: Add check if passed iface pointer is NULL

This is not true for MCUX's eth_rx() (in eth_mcux.c), where we can
execute eth_stats_update_errors_rx() after net_recv_data() returning
-EINVAL because of passed NULL iface pointer.

This change fixes routing for routes when the nexthop is a link-local
address of a connected peer.

The issue was that nexthop was correctly set from the routes, but the
code did not detect that the nexthop address (link local of the pc on
ppp interface) was on the ppp interface, because
net_if_ipv6_addr_onlink() only evaluated the network prefix and not
any other information (like the nbr list).

c951d71eba net: check permissions on net contexts
The original sockets system calls used file descriptors which
were actually net_context pointers. For all socket system calls,
any calls from user mode would check if the caller had permission
to use the net context.

This was later changed to not stuff net_context pointers into file
descriptors, but all the permission checking was unintentionally
lost, allowing all threads on the system to
read/write all socket file descriptors in the system at will, with
no way to isolate applications running on the same microcontroller
from each other's network activity.

This patch restores the permission checks on network context objects
for socket system calls that originated from user mode.

The call to z_object_recycle() was never removed from
zsock_socket_internal(); this is again leveraged to grant the
caller who opened the socket permission on the net_context
associated with the returned file descriptor.

To ensure that all socket calls do this checking, all uses of
z_get_fd_obj_and_vtable() have been routed through get_sock_vtable().

Objects have initialization state set and thread permissions
reset to just the caller in common zsock_socket() code.
