The main and idle threads, and their associated stacks,
were being referenced in various parts of the kernel
with no central definition. Expose these in kernel_internal.h

The main and idle threads were being defined statically,
with another variable exposed to contain their pointer

to user threads anyway, just expose the actual thread
objects.

This macro is slated for complete removal, as it's not possible
on arches with an MPU stack guard to know the true buffer bounds
without also knowing the runtime state of its associated thread.
As removing this completely would be invasive to where we are
in the 1.14 release, demote to a private kernel Z_ API instead.
The current way that the macro is being used internally will
not cause any undue harm, we just don't want any external code
depending on it.

DNS callback needs "struct shell *shell" data structure to pass as
a parameter to shell print. How it was achieved previously is that
it was packaged together with cosmetic "bool first" param into
"struct net_shell_user_data" on the stack, and passed to the
callback. The problem was that the original command handler then
returned, so the "struct net_shell_user_data" on the stack was
overwritten, and the callback crashed on accessing it.
An obvious solution was to make that structure static, but that would
leave to issues still, as turns out we allow system shell to be run
as more than one concurrent instances.
Next solution was to keep this structure on the stack, but block the
command handler until callback is finished. However, that hit a
deadlock due to not well thought out use of a mutex in the shell
printing routines.
The solution presented here is due to @nordic-krch, who noticed that
"bool first" param is indeed cosmetic and not really required. Then
we have only "struct shell *shell" to pass to the callback, and can
do that in callback's pointer param directly, ditching
"struct net_shell_user_data" which needs to be stored on the stack.

This commit introduces a concept of mesh-local IPv6 addresses. Such

should not be used to communicate with different subnets (i. e.
destinations outside the mesh).
As `addr_type` field already holds different kind of information
(whether address was created automatically/manually) it was not used in
this case.
Instead a mesh_local flag was added, so that we do not lose information
on how address was created. Address with such flag set will only be
selected as a source address automatically if the destination address
is within the same subnet it belongs to.

The net-shell "net allocs" command should print network buffer
allocations even if network packet debugging is not enabled.
This is how it used to work earlier but the behaviour got lost
at some point. So user needs to set CONFIG_NET_DEBUG_NET_PKT_ALLOC
in order to see the buffer allocations. The option will be enabled
by default if network packet log level is set to DBG.
The reason for a separate option is that the network packet debug
logging prints just too much data and it is very difficult to
track allocations when that happens.

There are too many individual requests for Qav related parameters. There

so far would render the eth mgmt API dominated by Qav parameters. That
would make the file hard to read and understand.
Instead of that - use a single GET and SET requests for all Qav
parameters. This works by adding a separate enum with Qav request type

Instead of always allocating both IPv6 and IPv4 address information
to every network interface, allow more fine grained address
configuration. So it is possible to have IPv6 or IPv4 only network
interfaces.
This commit introduces two new config options:
CONFIG_NET_IF_MAX_IPV4_COUNT and CONFIG_NET_IF_MAX_IPV6_COUNT
which tell how many IP address information structs are allocated
statically. At runtime when network interface is setup, it is then
possible to attach this IP address info struct to a specific
network interface. This can save considerable amount of memory
as the IP address information struct can be quite large (depends
on how many IP addresses user configures in the system).
Note that the value of CONFIG_NET_IF_MAX_IPV4_COUNT and
CONFIG_NET_IF_MAX_IPV6_COUNT should reflect the estimated number of
network interfaces in the system. So if if CONFIG_NET_IF_MAX_IPV6_COUNT
is set to 1 and there are two network interfaces that need IPv6
addresses, then the system will not be able to setup IPv6 addresses to
the second network interface in this case. This scenario might be
just fine if the second network interface is IPv4 only. The net_if.c
will print a warning during startup if mismatch about the counts and
the actual number of network interface is detected.
