When DTLS client was added to `poll` before/during the handshake, it
could throw errors and in some circumstances (when polling thread was
cooperative and had higher or equal priority to the handshake thread)
could lead to a deadlock in the application.
Prevent that, by blocking on handshake semaphore instead of fifo. Poll
will start using fifo for data poll only after handshake is complete.

Instead of simple bool value, use a semaphore to notify that TLS

Errno value is only significant when `recvfrom` function indicated an
error (by returning -1). We should not depend on it's value if no error
is notified.
As the return value of `recvfrom` is already checked, misused errno
verification can simply be removed.

Introduce toolchain_cc_asm macro to capture toolchain specific flags
related to assembly.
-D_ASMLANGUAGE is kept common for all, assuming -D as define flag is
supported by all compilers (which is almost the case).
No functional change expected.
Clang's flags are compatible with gcc, and are thus inherited.
This is motivated by the wish to abstract Zephyr's usage of toolchains,
permitting easier porting to other (commercial) toolchains.

Functions which have to be located in RAM are placed by SiLabs library
code in section '.ram'. Corresponding section used by Zephyr is called
'.ramfunc'. This patch renames SiLabs naming to match Zephyr's.
This solution was chosen over adding '.ram' function to Zephyr linker
scripts not to pollute them. However, this patch needs to be reapplied
every time SiLabs library version is updated.

Instead of having to enable ramfunc support manually, just make it
transparently available to users, keeping the MPU region disabled if not
used to not waste a MPU region. This however wastes 24 bytes of code
area when the MPU is disabled and 48 bytes when it is enabled, and
probably a dozen of CPU cycles during boot. I believe it is something
acceptable.
Note that when XIP is used, code is already in RAM, so the __ramfunc
keyword does nothing, but does not generate an error.

extract_property() is meant to generate #defines for a single property,
like 'foo = <1 2 3>'. Currently, it also generates node-level #defines
related to parent buses.
That makes the intent of the code hard to understand, and also means
that identical node-level #defines get redundantly added multiple times
(once per property).
Generate the node-level bus #defines before processing properties, in
generate_node_defines(). Use a new generate_bus_defines() helper.

Due to the way the code was structured,
flash.extract_partition(node_path) was called multiple times for the
same 'node_path'.
That must've been a mistake to begin with (but was hard to spot before
the code was cleaned up). Move the generation of per-node #defines out
of the property loop.

Secondarily, we rename include/posix/sys/types.h to
include/posix/posix_types.h so that we aren't getting a name collusion
with the system sys/types.h and that we can easily and clearily include
it (which we need to do to pull in the info from newlib).
