Empty RPL HBH header will be inserted while finalizing IPv6 packet
but updated after finding nexthop and sent the packet. In case of
Bluetooth or multicast dst address it was missed. Resulted in
empty RPL HBH header and packet dropped at peer node. It should
be updated in all circumstances.

The mbedtls debugging function was set before the ssl config
struct was initialized. This meant that it was not possible
to activate mbedtls debug prints. This commit sets the debug
print option after the config struct has been initialized.

Fixed also the debug prints which print extra \n which looks
very bad in debugging outputs.

This commit does not enable mbedtls debugging, it just makes it
possible to output mbedtls debug prints. In order to get mbedlts
debug prints one needs to do this:
* set DEBUG_THRESHOLD to >0 in http_server.c
* enable CONFIG_NET_DEBUG_HTTP in project config file
* enable MBEDTLS_DEBUG_C in mbedtls config file (see file pointed
  by CONFIG_MBEDTLS_CFG_FILE option)
* in qemu, one needs to increase the size of the available RAM,
  this setting does the trick, CONFIG_RAM_SIZE=300

Semantics of ENOENT error as used previously is "named entity not
found", whereas for "I/O handle is not valid", there's EBADF. For
example, POSIX/SUSV2 doesn't even list ENOENT as a possible error
for accept(), connect(), recv(), etc. whereas it lists EBADF, e.g.:

On some devices, when k_cpu_idle() was called we were getting
interrupts that were not the timer interrupt. On bbc_micro
a power clock control driver interrupt was happening instead
and k_cpu_idle() was returning without the system tick advancing,
failing the test.

The clock control interrupts seem to only happen early in device
boot; moving the idle test much later lets the test pass on this
board (and likely all other NRF5 based boards).

Stack sentinel doesn't prevent corruption, it just notices when
it happens. Any memory could be in a bad state and it's more
appropriate to take the entire system down rather than just kill
the thread.

Fatal testcase will still work since it installs its own
_SysFatalErrorHandler.
Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>

- _SysFatalErrorHandler is supposed to be user-overridable.
The test case now installs its own handler to show that this
has happened properly.

- Use TC_PRINT() TC_ERROR() macros

- Since we have out own _SysFatalErrorHandler, show that
k_panic() works

- Show that _SysFatalErrorHandler gets invoked with the expected
reason code for some of the scenarios.

One of the stack sentinel policies was to check the sentinel
any time a cooperative context switch is done (i.e, _Swap is
called).

This was done by adding a hook to _check_stack_sentinel in
every arch's __swap function.

This way is cleaner as we just have the hook in one inline
function rather than implemented in several different assembly
dialects.

The check upon interrupt is now made unconditionally rather
than checking if we are calling __swap, since the check now
is only called on cooperative _Swap(). The interrupt is always
serviced first.

The sample app "static_lib" is very important to Zephyr user, which
demonstrate how to build and link a static lib.
ISSM team wanted to integrate this app in their IDE for quark platforms.
However they find the in "static_lib/hello_world/Makefile" BOARD is
hardcoded as qemu_x86.

This patch supports other BOARD passed from build command.
I have verified this app working fine @Arduino101.

Nothing about this test requires tickless idle and it's not even
turned on in prj.conf.
Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>

The kernel tracks time slice usage with the _time_slice_elapsed global.
Every time the timer interrupt goes off and the timer driver calls
_nano_sys_clock_tick_announce() with the elapsed time, this is added to
_time_slice_elapsed. If it exceeds the total time slice, the thread is
moved to the back of the queue for that priority level and
_time_slice_elapsed is reset to zero.

In a non-tickless kernel, this is the only time _time_slice_elapsed is
reset.  If a thread uses up a partial time slice, and then cooperatively
switches to another thread, the next thread will inherit the remaining
time slice, causing it not to be able to run as long as it ought to.

There does exist code to properly reset the elapsed count, but it was
only compiled in a tickless kernel. Now it is built any time
CONFIG_TIMESLICING is enabled.

The REGION bits (bit[3:0]) of MPU_RBAR register can specify the number
of the region to update if the VALID bit (bit[4]) is also set.

If the bit[3:0] of "region_addr" are not zero, might cause to update
unexpected region. This could happen since we might not declare stack
memory with specific alignment.

This patch will mask the bit[4:0] of "region_addr" to prevent updating
unexpected region.

64-bit types were not being handled properly and depending on the
calling convention could result in garbage values being printed.

We still truncate these to 32-bit values, the predominant use-case
is printing timestamp delta values which generally fit in a 32-bit
value. However we are no longer printing random stuff.
