This was felt to be necessary at one point but actually isn't.
- When a thread is initialized to use a particular stack, calls will be
made to the MMU/MPU to restrict access to that stack to only that
thread. Once a stack is in use, it will not be generally readable even
if the buffer exists in application memory space.
- If a user thread wants to create a thread, we will need to have some
way to ensure that whatever stack buffer passed in is unused and
appropriate. Since unused stacks in application memory will be generally
accessible, we can just check that the calling thread to
k_thread_create() has access to the stack buffer passed in, it won't if
the stack is in use.
On ARM we had a linker definition for .stacks, but currently stacks are
just tagged with __noinit (which is fine).

prepare_arp() was unreferencing original pkt (called pending there) in
case of error.
net_prepare_arp() was always unreferencing pkt, though it could have
been already unreferenced by prepare_arp() as seen previously which is
an extra bogus unref in this case.
And in case it returned NULL, ethernet_send() would return NET_DROP
which in turn would make net_if's tx code to unref again the pkt.
This patch ensures pkt is unrefed only once and at the right place.

Previously, this was only done if an essential thread self-exited,
and was a runtime check that generated a kernel panic.
Now if any thread has k_thread_abort() called on it, and that thread
is essential to the system operation, this check is made. It is now
an assertion.
_NANO_ERR_INVALID_TASK_EXIT checks and printouts removed since this
is now an assertion.

It's now possible to instantiate a thread object, but delay its
execution indefinitely. This was already supported with K_THREAD_DEFINE.
A new API, k_thread_start(), now exists to start threads that are in
this state.
The intended use-case is to initialize a thread with K_USER, then grant
it various access permissions, and only then start it.

All system calls made from userspace which involve pointers to kernel
objects (including device drivers) will need to have those pointers
validated; userspace should never be able to crash the kernel by passing
it garbage.
The actual validation with _k_object_validate() will be in the system
call receiver code, which doesn't exist yet.
- CONFIG_USERSPACE introduced. We are somewhat far away from having an
end-to-end implementation, but at least need a Kconfig symbol to
guard the incoming code with. Formal documentation doesn't exist yet
either, but will appear later down the road once the implementation is
mostly finalized.
- In the memory region for RAM, the data section has been moved last,
past bss and noinit. This ensures that inserting generated tables
with addresses of kernel objects does not change the addresses of
those objects (which would make the table invalid)
- The DWARF debug information in the generated ELF binary is parsed to
fetch the locations of all kernel objects and pass this to gperf to
create a perfect hash table of their memory addresses.
- The generated gperf code doesn't know that we are exclusively working
with memory addresses and uses memory inefficently. A post-processing
script process_gperf.py adjusts the generated code before it is
compiled to work with pointer values directly and not strings
containing them.
- _k_object_init() calls inserted into the init functions for the set of
kernel object types we are going to support so far
