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).

f1920fff46 net: sockets: tls: Block DTLS client in poll until handshake is complete
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.

75f77db432 include: misc: util.h: Rename min/max to MIN/MAX
There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.

This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.

All files that use these macros have been updated.

cf47c89971 net: lwm2m: add support for IPSO Timer object
Initial implementation of IPSO Timer object #3340
Based on: http://www.openmobilealliance.org/tech/profiles/lwm2m/3340.xml

"This IPSO object is used to time events and actions, using patterns
common to industrial timers. A POST to the trigger resource or On/Off
input state change starts the timing operation, and the timer
remaining time shows zero when the operation is complete. The
patterns supported are One-Shot (mode 1), On-Time or Interval
(mode 2), Time delay on pick-up or TDPU (tmode 3), and Time Delay
on Drop-Out or TDDO (mode 4). Mode 0 disables the timer, so the output
follows the input with no delay. A counter is provided to count
occurrences of the timer output changing from 0 to 1. Writing a value
of zero resets the counter. The Digital Input State resource reports
the state of the timer output."

NOTE: Only One-Shot Mode (mode 1) is implemented in this patch.

024a7e0502 net/sockets: Adapt net_pkt_get_src_addr to new net_pkt API
This function is only used in sockets, thus making it a private function
of socket library and renaming it relevantly.

Note that sockets should be reviewed at some point to avoid using such
function: zsock_received_cb() already get the ip header and the protocol
header, so it could grab the src addr/port from there. It would be way
more optimized to do so, since net_pkt_get_src_addr is costly as it
parses all over again the ip/protocol headers.

net_pkt_get_src_addr/net_pkt_get_dst_addr are removed.

This version supports basic packet socket features.
Protocol family is AF_PACKET, type of socket is
SOCK_RAW and proto type is ETH_P_ALL. The user will
receive every packet (with L2 header) on the wire.
For TX, the subsystem expects that the user has set
all the protocol headers (L2 and L3) properly.

Networking subsystem doesn't verify or alter the headers while
sending or receiving the packets. This version supports packet
socket over Etherent only. Also combination of other family
and protocols doesn't work (i.e. Application can not open
packet-socket and non packet-socket together).
