3609e261bb net: sockets: move fcntl back to socket_offload.c
We are reverting the changes in commit
55b3f05932 given build errors are seen
when fcntl.h is included, as it declares fcntl() as a non-static
function. The same function cannot be declared as both static and
non-static.

Instead, we avoid redefining fcntl() in lib/os/fdtable.c specifically
for case of the SimpleLink family, til we have support for the new
socket_op_vtable.

cf322c44db net: Switch usage of net_pkt_get_reserve to net_pkt_alloc
Some places were still using the old allocator. Using the new one does
not change any behavior. This will help to remove the useless data_len

5499f38e7a net: socket: Increment TCP context refcount on socket(), accept()
TCP context is effectively owned by both application and the stack:
stack may detect that peer closed/aborted connection, but it must
not dispose of the context behind the application back. Likewise,
when application "closes" context, it's not disposed of immediately,
there's yet closing handshake for stack to perform.

This effectively means that TCP contexts have refcount of 2 when
they're created. Without this change, following situation is
possible: peer opens connection, an app get a context (or socket)
via accept, peer sends data, closes connection. An app still holds
a reference to connection, but stack may dispose of context, and
even reuse it for a new connection. Then application holds a reference
to either free, or completely different context.

This situation was very clearly and 100% reproducible when making
Zephyr port of open62541 library, which works in async manner using
select().

4344e27c26 all: Update reserved function names
Update reserved function names starting with one underscore, replacing
them as follows:
   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'
   '_Cstart' with 'z_cstart'
   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

Various generator scripts have also been updated as well as perf,
linker and usb files. These are
   drivers/serial/uart_handlers.c
   include/linker/kobject-text.ld
   kernel/include/syscall_handler.h
   scripts/gen_kobject_list.py

214ef00db3 kconfig: subsys: net: Remove redundant dependencies
subsys/net/lib/lwm2m/Kconfig.ipso is 'source'd within an 'if LWM2M', in
subsys/net/lib/lwm2m/Kconfig, so the 'depends on LWM2M' is redundant.

The 'depends on NET_IPV4' and 'depends on NET_L2_OPENTHREAD' are within
corresponding 'if's in the same file.

'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. There are no
"conditional includes" in Kconfig, so 'if FOO' has no special meaning
around a source. Conditional includes wouldn't be possible, because an
if condition could include (directly or indirectly) forward references
to symbols not defined yet.

Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

5a44011e3b net: sockets: Add dummy impl for SO_REUSEADDR and TCP_NODELAY sockopts
These options are oftentimes used when implementing servers, and
thus required to port existing socket apps. These options are also
safe to just ignore, e.g. SO_REUSEADDR has effect only for repeated
recreation of server socket (not an expected usecase for a Zephyr
app), while TCP_NODELAY is effectively the default for Zephyr, as we
don't implement TCP buffering (aka Nagle algorithm).
