Set TP in exception context so that it gets loaded into the CPU when
first running the thread. Set TP for secondary cores to related idle TLS
area.

When a stack overflow is caught by an MPU region, the stack pointer will
end up inside that area when the exception is handled. Handling the
exception involves pushing an exception frame onto the same stack. If
there's not enough space remaining below the faulting SP value, the
memory region below the stack will get corrupted.
We protect against this by making the stack guard larger than the 0x20
bytes necessary to hold an exception frame. To avoid lots of conditional
complexity here, the guard is set to 0x40 bytes if the MPU minimum size
is not larger than 0x20 bytes.

V7-A also supports TPIDRURO, so go ahead and use that for TLS, enabling
thread local storage for the other ARM architectures.
Add __aeabi_read_tp function in case code was compiled to use that.

Making context switch cache-coherent in SMP is hard. The
KERNEL_COHERENCE handling was conservatively invalidating the stack
region of a thread that was being switched in. This was because it
might have (1) run on this CPU in the past, but (2) run most recently
on a different CPU. In that case we might have stale data still in
our local dcache!
But this has performance impact in the (very common!) case of a thread
being switched out briefly and then back in (e.g. k_sleep() for a
small duration). It will come back having lost all of its cached
stack context, and will have to fetch all that information back from
shared SRAM!
Treat this by tracking a "last_cpu" for each thread in the arch part
of the thread struct. If we're coming back to the same CPU we left,
we know we can skip the invalidate.

DAD timeout was wrongly checking the reply order. The code will always
assign sequentially the reply to 0-2 with the current uptime. This means
that we will always have dad[0] < dad[1] < dad[2]. Check it is useless.
Instead, let just check if we got all replies.
The test checking the time between the first and last request is to
fragile. It is testing a constant independently of the tested platform
failing in several of them. Just remove it.

.module_init sections is used to keep all components constructor
functions.
Zephyr uses -ffunction-sections option which will create a section for
each function. Unfortunately, this creates a section named .module_init
for the function module_init() used to initialize the processing module
generic layer.
Thus, places module_init() in the constructor area named .module_init
which is wrong.
To avoid this we rename .module_init section for constructors to
.initcall.

The function setsockopt() option TLS_CIPHERSUITE_LIST
allows the user to set a specific list of ciphersuites
when using the Zephyr native + Mbed TLS stack. However, the
list provided was not actually being used later for
handshaking.
This adds the missing calls to mbedtls_ssl_conf_ciphersuites()
to use the list provided. If none was provided, fall back
to the default list as determined by Mbed TLS from Kconfig
values.
