1eb4a709e8 net: dns: Allow using resolver and responder at the same time
Allow mDNS resolver and responder to to be used at the same
time so that both can use the port 5353. This requires
a DNS traffic dispatcher which affects also the normal DNS
resolver.

Fixes #72553

7bfaca4c58 net: dns: Add DNS cache for improved performance
In order to reduce dns resolve requests when using the dns
resolver an optional cache was introduced. This cache
retains query requests for the TTL duration and therefore
prevents premature refetching of DNS RRs.

bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

8cf8db3a73 Kconfig: Use a short, consistent style for prompts
Consistently use

    config FOO
            bool/int/hex/string "Prompt text"

instead of

    config FOO
            bool/int/hex/string
            prompt "Prompt text"

(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).

The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.

Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/
how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some
of the rarer variations had to be converted manually.

1073882998 subsys: kconfig: Remove 'default n' properties and clean up a bit
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Remove some 'default ""' properties on string symbols too.

Also make definitions more consistent by converting some

  config FOO
  	<type>
  	prompt "foo"

definitions to a shorter form:

  config FOO
  	<type> "foo"

This shorthand works for int/hex/string symbols too, not just for bool
symbols.

b833d010eb net: llmnr: Add LLMNR responder support
This allows zephyr to listen LLMNR DNS queries sent by Windows
and respond to them. See RFC 4795 for details.

The feature requires that hostname is set properly to the
zephyr device and LLMNR is configured properly.

Typically following config options are enough for this support:

CONFIG_NET_HOSTNAME_ENABLE=y
CONFIG_NET_HOSTNAME="zephyr-device"
CONFIG_DNS_RESOLVER=y
CONFIG_LLMNR_RESPONDER=y

c7da45f9e2 net: Enable logging in more modules if CONFIG_NET_LOG_GLOBAL defined
This is useful to enable error/warning logging across the net
codebase (less useful for debug level logging, but that's true
for CONFIG_NET_LOG_GLOBAL already).

Implementation-wise, instead of keeping adding to long list of
"select"'s in CONFIG_NET_LOG_GLOBAL and thus introduce component
inter-dependencies, add "default y if NET_LOG_GLOBAL" to
individual components' logging options.

Manually updated subsys/logging/sys_log.c that had a malformed

had a SPDX tag and we either got a duplicate or missed updating.
