The net_timeout structure is documented to exist because of behavior
that is no longer true, i.e. that `k_delayed_work_submit()` supports
only delays up to INT32_MAX milliseconds. Nonetheless, use of 32-bit
timestamps within the work handlers mean the restriction is still
present.
This infrastructure is currently used for two timers with long
durations:
* address for IPv6 addresses
* prefix for IPv6 prefixes
The handling of rollover was subtly different between these: address
wraps reset the start time while prefix wraps did not.
The calculation of remaining time in ipv6_nbr was incorrect when the
original requested time in seconds was a multiple of
NET_TIMEOUT_MAX_VALUE: the remainder value would be zero while the
wrap counter was positive, causing the calculation to indicate no time
remained.
The maximum value was set to allow a 100 ms latency between elapse of
the deadline and assessment of a given timer, but detection of
rollover assumed that the captured time in the work handler was
precisely the expected deadline, which is unlikely to be true. Use of
the shared system work queue also risks observed latency exceeding 100
ms. These calculations could produce delays to next event that
exceeded the maximum delay, which introduced special cases.
Refactor so all operations that use this structure are encapsulated
into API that is documented and has a full-coverage unit test. Switch
to the standard mechanism of detecting completed deadlines by
calculating the signed difference between the deadline and the current
time, which eliminates some special cases.
Uniformly rely on the scanning the set of timers to determine the next
deadline, rather than assuming that the most recent update is always
next.

A dedicated LwM2M execute callback type has been implemented which
supports execute arguments. The lwm2m engine, lwm2m_client sample and
lwm2m objects have been updated accordingly. Also the API change has
been documented, and the lwm2m engine reference has been updated.
Fixes#30551.

Currently, after `CONFIG_LWM2M_RD_CLIENT_SUPPORT_BOOTSTRAP` is enabled,
the LwM2M engine will initiate bootstrap procedure on each run. This
approach limits the flexibility of the application, as it's not always
necessary to go over the bootstrap procedure (for instance, the
application may decide to store the security object obtained during the
bootstrap in flash, and restore it on boot).
Fix this by introducing an additional `flags` parameter to the
`lwm2m_rd_client_start()` function, which provides information whether
to run bootstrap in the current session or not.

Following the change to use the C domain for parsing, update all

well, if used, because they are not needed, this is already known to be
a function, and how it is displayed in the documentation later is a
semantic decision done by the output builder.

Instead of using a custom offloading interface, users can use
`NET_SOCKET_REGISTER` macro to register custom socket API provider. This
solution removes a limitation, that only one offloaded interface can be
registered and that it cannot be used together with native IP stack.
The only exception remainig are DNS releated operations -
`getaddrinfo`/`freeaddrinfo`, which, when offloaded, have to be
registered specifically.

`TLS_PEER_VERIFY` and `TLS_DTLS_ROLE` options accept specific values,
yet no symbols were defined for them. In result, magic numbers were used
in several places, making the code less readable.

and using them in places where related socket options are set.

Linking to API material requires knowing the pecularities of how
doxygen, sphinx, and breathe work. In an attempt to hide some of this
we're preparing the current docs to allow use of configuration defaults
that will let us more simply use a default role that will hunt for a
reference target in the various domains that are available by using a
default "role" of "all". This will let us use the simple notation
`functionname` or `typename` without fully specifying the reference as
:c:func:`functionname`.
This patch cleans up exising docs that were (incorrectly) using single
backtics where double backtics should have been used, and also found
some typos (such as a space between the role name and the reference,
such as :file: `filename`, and a missing colon such as
c:func:`functionname`)
