Add a <misc/math_extras.h> header file with portable implementations of
a number of commonly used math and bit counting operations that are not
available in the C programming language.
The math_extras functions fall into two groups:
1. Unsigned integer arithmetic with overflow detection. Addition and
multiplication are provides for the u32_t, u64_t, and size_t types.
This commit doesn't include subtraction and division, and there are
no signed operations. These could be added later if there is a need.
2. Bit-counting operations like clz, ctz, and ffs. These are provided
for u32_t and u64_t only. I don't see a need for size_t operations,
but they could be added if needed.
A follow-on commit will add more efficient implementations using
compiler builtins for those compilers that support it.
Another commit will replace other uses of "naked" compiler builtins with
calls to these functions.

This commit adds support for board: nrf52811_PCA10056.
The nRF52840 DK: PCA10056 is the recommend development kit, it emulates
the nRF52811, and can be used as a starting point for development
before moving over to a custom board.
Please note that this development kit does not support Bluetooth
Direction Finding. What is more it cannot be used with most of Arduino
shields because of PCA10056 PIN layout.

During the write abort test, a second write is started then quickly
aborted. This means that the number of bytes sent is relative
to that second write. So when comparing it against the number
of bytes received which is NOT reset, the first (completed)
send of five bytes has to be accounted for. The current
nrfx implementations abort quick enough that no bytes are reported
sent, so this wasn't currently being exercised (i.e. the short
circuit of zero bytes sent was taken).
Tested on nrf52840_pca10056.

Some configuration for the boards have to be added into test_adc.c file
so user can test driver with the test cases. Several nucleo boards are
added including F091RC/F103RB/F207ZG/F302R8/F401RE/F746ZG/L073RZ/L476RG.
And also ADC dts and pinmux configuration are added into boards own
pinmux.c and dts file.

According to POSIX, that's the header which defines this function.
Similarly, nothing in POSIX indicates that <time.h> should have
access to struct timeval, so it's removed (it's made accessible
to <sys/time.h> via <sys/_timeval.h> introduced earlier).

It is convenient to have a blocking version of

There were various flaws in it that motivated its removal:
- No hash collision handling mechanism. In case that would happen, the
behavior of the network connection would be unknown. This is the main
drawback
- The lookup is not that much more efficient than the default one. The
only difference of gain is in connection comparison (a u32t comparison
vs a full connection compare). But the list handling is the same. It's
made worse by the presence of a negatives match array which can be
easily filled in and becomes then fully usless, appart from consuming
CPU. As well as adding a new connection: it requires the whole cache
to be cleared which is unefficient.
- Not memory efficient, even compared to a proper hash table.
Two arrays instead of one etc...
All of this could be fixed by using a proper hash table, though it
remains to be seen if such object could fit in Zephyr core.

This test uses ztest anyway, the default should be fine
just like any other test running under ztest.
k_thread_create() uses a lot of stack, and the main
stack size is very small if ztest is enabled. Do it in
another ztest task instead.
We don't need to mess with the main thread's priority,
just have the alt thread run cooperatively.

The various struct pipe_sequence were not located in memory
accessible to user mode. With optimization turned on, they
weren't in memory at all, but with code coverage enabled
the arrays were actually being read, resulting in memory
access failures from user mode.
Fix them by placing in ROM, they never get modified.

device_get_binding() compares pointers first before doing strcmp().
However, enabling coverage forces -O0 to disable any compiler
optimizations. There would be multiple copies of the same string,
and the code pathing doing pointer comparsion would not be tested
at all. So add this flag to merge string constants such that
the pointer comparison would be exercised.
This also adds a bad driver which fails initialization. This is
to make sure that execution path is covered.

As the getaddrinfo() test is suppose to be self contained, then
we will need to install handler for the sent DNS query. After we
receive the query in process_dns() thread, we verify that the
query was sent properly. We do not return DNS reply back to
the caller in this case as we do not want to create DNS server
just for this simple test application. This can be changed later
if we get DNS server functionality in Zephyr network stack.
