For systems without userspace enabled, these work the same
as a k_mutex.
For systems with userspace, the sys_mutex may exist in user
memory. It is still tracked as a kernel object, but has an
underlying k_mutex that is looked up in the kernel object
table.
Future enhancements will optimize sys_mutex to not require
syscalls for uncontended sys_mutexes, using atomic ops
instead.

The legacy struct s_coopFloatReg was never being used, though it was
an empty struct (not wasting space), some symbols were being generate
for it.
Nevertheless, neither C99 nor C11 allow empty structs, so this
was also a violation to the C standards.

DNS is not part of L3, but as dhcpv4 or the net shell, it is a services
on top of the network stack. So let's gather all in a dedicated
function.
This also rework the order when starting the DNS service. There was an
issue for offload device: these would be fully initialized in
init_rx_queues() which was called after l3_init. l3_init had already
started dns: which would not be able to bind correctly, proving to be
fully dead afterwards. Instead, starting the dns at the very end
ensures that all is initialized properly from devices to stack.

Ports B and C share a common interrupt vector on kw40 and kw41z socs,
but we don't currently have a way to express this in device tree. A
check was added in commit 77cb942a97 that
correctly causes build errors on kw40/41 boards when both ports are
enabled.
Disable the port b interrupt for now until we have a better way to
handle this.

It's really not possible to design a test where we can
enforce expectations on real vs. expected stack size:
- Some platforms may increase stack size over what is expected
due to rounding up the stack buffer area to the next power
of two.
- Some configuration options like CONFIG_STACK_RANDOM
carve out space in the stack buffer, resulting in a stack
size less than what is expected.
Best we can do is just assert that the amount of space
available should be less than the total size reported.

The spec allows to set to no specific value with use of 0xffff.
As this still enables entering values in the invalid range, 3200-65535
for min/max interval, this adds the necessary build checks to prevent
values within this range to be used and at same time check if min
interval is not bigger that max interval.

USBDETECTED event is be generated on cable attachment and
when cable is already attached during reset, but not when
the peripheral is re-initialized. When USB-enabled bootloader
is used, target application will not receive this event
and it needs to be generated again. This commit implements
a check against driver being enabled multiple times in case
of application without bootlader starting with cable attached
(both "fake" and "real" events are generated). Such dirty
trick allows bootloader to leave the peripheral in any state
before jumping to target application.

Previous commit c31e659165 changed
the ALWAYS_INLINE macros to avoid functions being inlined for
the purpose of code coverage. This has a side effect of causing
the text sections of kobject_hash.c and priv_stacks_hash.c
to ballon more than 10 times in size. This is caused by
attaching the unused attribute, which results in all those
functions being in the text sections though they are never
used. So just keep the "inline" there.
This also removes -fno-inline from NO_COVERAGE_FLAGS so these
two files are not compiled with flags related to code coverage.

In order to advertise directed to a privacy enabled central the
initiator field of the directed adv packet needs to set to an RPA.
To instruct the controller to use an RPA in the initiator field own
address type should be set to either 0x02 or 0x03.
Since it is not certain that a remote device supports address resolution
of the initiator address we add an option to turn this on and give the
application the responsibility to check if peer supports this.

If the TCP segment is not sent properly by L2, then do not mark
it "not sent" in net_if.c:net_if_tx(). That "not sent" marking
confused TCP ref counting in tcp.c:tcp_retry_expired() and caused
the packet to be freed too early which then caused free net_buf
access issue during packet resend. This free memory access was
seen with zperf sample application.
From TCP point of view, the packet can be considered sent when
it is given to L2. The TCP timer will resend the packet if needed.

This reverts commit 9cd547f53b.
The commit we are reverting, fixed originally the issue that was
seen with zperf. There we freed the net_pkt too early while it was
still waiting for a TCP ACK. The commit 9cd547f5 seemd to fix that
issue but it was causing issues in dump_http_server sample app which
then started to leak memory. No issues were seen with echo-server
with or without the commit 9cd547f5.
So the lessons learned here is that one needs to test with multiple
network sample apps like dump_http_server, echo_server and zperf
before considering TCP fixes valid, especially fixes that touch
ref counting issues.
