e8620e2cca ext: mbedtls: Unify mbedTLS Kconfig prefixes
Currently there is a mixed approach in prefixes from mbedTLS
configuration (MBEDTLS_ and TLS_). The latter was used in generic config
file and could bring up confusion that it can only be used with TLS
subsystem. Hence unify the approach to MBEDTLS_ prefix to avoid such
confusion.

13b38ed686 lib: fdtable: Change ioctl vmethod signature to take va_list
As extend fdtable usage to more cases, there regularly arises a need
to forward ioctl/fcntl arguments to another ioctl vmethod, which is
complicated because it defined as taking variadic arguments. The only
portable solution is to convert variadic arguments to va_list at the
first point of entry from client code, and then pass va_list around.

To facilitate calling ioctl with variadic arguments from system code,
z_fdtable_call_ioctl() helper function is added.

ee0b61fff8 net: sockets: Rework poll to support ioctl helper commands
This commit reworks socket poll implementation to support multiple
socket implementations.

To achieve that, two ioctl poll helper requests were added:
ZFD_IOCTL_POLL_PREPARE and ZFD_IOCTL_POLL_UPDATE. The poll
implementation calls ioctl with these requests for each socket
requested in the fds table.

The first request is responsible for preparing k_poll_event objects
for specific socket. It can request to skip waiting in k_poll by
returning EALREADY through errno.

The latter request is responsible for processing outcome of k_poll for
each socket. It can request to retry the k_poll by returning EAGAIN
through errno.

5451ff2848 shell: remove "options" concept
Removing help "options" from shell API.

Currently SHELL_OPT macro is not used by users. What is more
commit: a89690d10f ignores possible options created in
command handler by the user. As a result they are not printed
in help message.

Second, currntly implemented "options" in command handlers options are
implemented without SHELL_OPT macro.

And last but not least this change will allow to implement
help handler in a way that user will not need to think about calling
functions printing help in a command handler.

c51cf1e463 drivers: wifi: simplelink: Implement setsockopt() for TLS offload
Implements setsockopt() for the socket offload driver
to process the TLS tags sent in via the Zephyr setsockopt() API,
when CONFIG_NET_SOCKETS_SOCKOPT_TLS is chosen.
For each tag, the credential filenames are retrieved and
set via SimpleLink's sl_SetSockOpt() API.

Also, creates a new KConfig option for TLS_CREDENTIAL_FILENAMES.
This new option is used by apps/protocols to add TLS credentials
via filenames referring to the actual content stored on a secure
file system or flash.

Handles the IPPROTO_TLS_* socket protocol families in the
socket() offloaded API.

This was validated on the cc3220sf_launchxl with the http_get sockets
sample, with the globalsign_r2.der file loaded to secure flash via
the TI Uniflash tool, and using the TI Catalog of known good
root CA's.

20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

f750ce56ce net: lib: sockets: Switch to use fdtable
Previously the "socket file descriptors" were just net_context
pointers cast to int. For full POSIX compatibility and support
of generic operations line read/write/close/fcntl/ioctl, the
real file descriptors should be supported, as implemented by
fdtable mini-subsys.

Socket implementation already has userspace vs flatspace dichotomy,
and adding to that ptr-fds vs real-fds dichotomy (4 possible cases)
is just too cumbersome. So, switch sockets to real fd's regardless
if full POSIX subsystem is enabled or not.

b8ffd9acd6 sys_clock: Make clock_always_on true by default
This flag is an indication to the timer driver that the OS doesn't
care about rollover conditions of the tick count while idling, so the
system doesn't need to wake up once per counter flip[1].  Obviously in
that circumstance values returned from k_uptime_get_32() are going to
be wrong, so the implementation had an assert to check for misuse.

But no one understood that from the docs, so the only place these APIs
were used in practice were as "guards" around code that needed to call
k_uptime_get_32(), even though that's 100% wrong per docs!

Clarify the docs.  Remove the incorrect guards.  Change the flag to
initialize to true so that uptime isn't broken-by-default in tickless
mode.  Also move the implemenations of the functions out of the
header, as there's no good reason for these to need to be inlined.

[1] Which can be significant.  A 100MHz ARM using the 24 bit SysTick
    counter rolls over at about 6 Hz, and if it had to come out of
    idle at that rate it would be a significant power issue that would
    swamp the gains from tickless.  Obviously systems with slow
    counters like nRF or 64 bit ones like RISC-V or x86's TSC aren't
    as affected.
