c57650c403 net: context: clean up net_context_get()
* reduced cyclomatic complexity
* group validation by family to make the validation easier to understand
and extend
* change preprocessor markup where possible to allow for complete code
elimination when features (esp. IP) are disabled
* renamed net_context_get/set_ip_proto() to net_context_get_proto()

While the latter is formally part of the public API and might therefore
have to be deprecated rather than renamed, it is considered internal API
by the net developers, see

9695a022f4 net: core: clean up inbound packet handling
The net_core:process_data() and connection:net_conn_input() methods are
the central network packet reception pipeline which:

1) guide network packets through all network layers,
2) decode, validate and filter packages along the way and
3) distribute packages to connections/sockets on all layers.

This code seems to have grown complex and rather cluttered over time as
all protocols, layers and socket implementations meet there in one single
place.

The code also reveals its origin as a pure IP stack which makes it hard
to introduce non-IP protocols and their supporting socket infrastructure
in a modularized way.

For an outside contributor it seems almost impossible to add another
protocol, protocol layer, filter rule or socket implementation without
breaking things.

This change doesn't try to solve all issues at once. It focuses
exclusively on aspects that maintain backwards compatibility:

* Improve modularization and encapsulation on implementation level by
disentangling code that mixes up layers, protocols and socket
implementations.

* Make IP just one protocol among others by removing assymmetry in
protocol handling logic and introduce preprocessor markup so that
IP-specific code can be eliminated by the preprocessor if not needed.

* Use preprocessor markup to delineate hook points for future
modularization or expansion without introducing structural changes (as
this would almost certainly break the API).

* Reduce cyclomatic complexity, use positive rather than negative logic,
improve variable naming, replace if/elseif/else blocks with switches,
reduce variable span, introduce inline comments where code does not
speak for itself, etc. as much as possible to make the code overall
more human-friendly.

Background: These are preparative steps for the introduction of IEEE
802.15.RAW sockets, DGRAM sockets and sockets bound to PAN IDs and device
addresses similar to what the Linux kernel does.

e9a433cd8f net: introduce NET_IP config to efficiently mark conditional code
The code contained several repeated composite IPv4/v6 and UDP/TCP
preprocessor statements that can be simplified by introducing a hidden
NET_IP preprocessor constant that captures what probably is actually
"meant" by this code.

While we were on it we also used the new constant to further isolate
IP-specific code from non-IP specific generics.

79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

fe7ffcf2e8 tls_credentials: add Trusted Credential storage backend

Protected Storage API, permitting storage of the credentials
offering a trusted long-term storage with integrity checks.

This implementation tries to fit the actual tls_credentials

- the buffer pointer returned by credetial_get & credential_next_get
  is dynamically allocated and differs from the one given to
  tls_credential_add since it's extracted from the storage at runtime.

f86027ffb7 kernel: pipes: rewrite pipes implementation
This new implementation of pipes has a number of advantages over the
previous.
  1. The schedule locking is eliminated both making it safer for SMP
     and allowing for pipes to be used from ISR context.
  2. The code used to be structured to have separate code for copying
     to/from a wating thread's buffer and the pipe buffer. This had
     unnecessary duplication that has been replaced with a simpler
     scatter-gather copy model.
  3. The manner in which the "working list" is generated has also been
     simplified. It no longer tries to use the thread's queuing node.
     Instead, the k_pipe_desc structure (whose instances are on the
     part of the k_thread structure) has been extended to contain
     additional fields including a node for use with a linked list. As
     this impacts the k_thread structure, pipes are now configurable
     in the kernel via CONFIG_PIPES.
