This patch fixes a regression which the original patch introducing
this code (improving concurrent connection handling) had on
*sequential* connection handling. Without this patch, with the
default CONFIG_NET_TCP_BACKLOG_SIZE of 1, after each connection
request, there was 1s (ACK timeout) "dead time" during which new
connection wasn't ptocessed.
This is because k_delayed_work_remaining_get() was checked the
wrong way. But there's no need to use k_delayed_work_remaining_get()
at all, instead just call k_delayed_work_cancel() and dispatch on
its return code.
Note that there's still a problem of synchronizing access to
the global array tcp_backlog, as worker (which modifies it) may
preempt packet handling code (which also modifies it).

The sequence number validator was checking the seq numbers
incorrectly. This caused some valid RST packets to be dropped
and the TCP stream to hang.
Added also a TCP test case that tests the seq validator.

Usually it is not enough to have just one IPv6 multicast
address defined for the network interface. So allocate three
IPv6 multicast addresses for the network interface as IPv6
by default uses multicast a lot. This hopefully will avoid
some mysterious errors if the addresses run out.
Note that this will increase memory usage a bit so you might
need to lower the count in your conf file if memory is low.

The commit 210c30805b ("net: context: Close connection fast
if TIME_WAIT support is off") was not a proper way of closing
the connection. So if Zephyr closes the connection (active close),
then send FIN and install a timer that makes sure that if the peer
FIN + ACK is lost, we close the connection properly after a timeout.

The commit 00ac0487b0 ("net: context: Remove tcp struct SYN-ACK

Adding that ACK timer back so that we can close the connection

Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
There could be situations where many services are changed in a row which
would cause k_sem_take to block on the second change, but if the calling
thread is actually the RX thread then this will deadlock since the RX
thread is the one processing the confirmations of indications and it is
blocked k_sem_give is never called.
To solve this the services changes are now offloaded to the system wq
and the code will attempt to consolidate the range being changed so only
one indication is send. If for some reason another changes is caused
while confirmation is pending we just reschedule it to run later to
avoid blocking the system wq in the same way.

Previously we were instantiating QEMU with 32MB of RAM but
only enabling a small fraction of it.
Now we boot with 8MB of ram. We ignore the first 4K so we can
make that an unmapped paged to catch NULL pointer dereferences.
If XIP is enabled, the "ROM" region will be the first half of
memory, the "RAM" region the latter.
Move the IDT_LIST and MMU_LIST regions elsewhere so they don't
overlap the new memory arrangement.
Use !XIP to fix a problem where CONFIG_RAM_SIZE was set incorrectly
for XIP case.

These special kernel sections represent arrays of kernel objects than
are iterated over at runtime to perform initialization.
The code expects all the data in these sections to be in the form of an
array of that section type, with each element sizeof(type) bytes apart.
Unfortunately, the linker sometimes has other plans and in some cases
was defaulting to aligning the data to some large power-of-two value,
such as 64 bytes. This causes any attempt to iterate over these sections
to fail as they are not a proper array.
Use the ld SUBALIGN() directive to force the alignment of these input
sections to 4 bytes.

Upcoming memory protection features will be placing some additional
constraints on kernel objects:
- They need to reside in memory owned by the kernel and not the
application
- Certain kernel object validation schemes will require some run-time
initialization of all kernel objects before they can be used.
Per Ben these initializer macros were never intended to be public. It is
not forbidden to use them, but doing so requires care: the memory being
initialized must reside in kernel space, and extra runtime
initialization steps may need to be peformed before they are fully
usable as kernel objects. In particular, kernel subsystems or drivers
whose objects are already in kernel memory may still need to use these
macros if they define kernel objects as members of a larger data
structure.
It is intended that application developers instead use the
K_<object>_DEFINE macros, which will automatically put the object in the
right memory and add them to a section which can be iterated over at
boot to complete initiailization.
There was no K_WORK_DEFINE() macro for creating struct k_work objects,
this is now added.
k_poll_event and k_poll_signal are intended to be instatiated from
application memory and have not been changed.
