This commit adds support for a 6LoCAN Ethernet border translator.

This is related to findings in #17997 and changes network related
header files to have include files outside of extern "C" { } block.
Declarations that use C linkage should be placed within extern "C"
so the language linkage is correct when the header is included by
a C++ compiler.
Similarly #include directives should be outside the extern "C" to
ensure the language-specific default linkage is applied to any
declarations provided by the included header.

Current SOCKS5 based connections in mqtt are only
TCP (nonsecure) based. To support TLS based SOCKS5
connections, new methods needs to be introduced.
Instead, removed CONFIG_MQTT_LIB_SOCKS based implementation.
And now mqtt provides an api to set proxy
(mqtt_client_set_proxy()) details. That's enough,
socket layer will take care of making connections through
proxy server.

Several problems with memset usage in the LwM2M subsystem were
identified:
- Every single object that can have multiple instances is using
memset to initialize static resource data during init. This data
will already be set to 0 because it is static, so the memset
statements are unneeded.
- Instead of using memset during object init which is only called
one time during kernel startup, let's add a memset to the
object create function to ensure the resource data is cleared out.
It could have been used prior and then released via a DELETE op.
- the IPSO Timer object was setting a lot of data structure members
to 0 in the create function. Let's do 1 memset on the entire
structure and then only the non-zero values afterward.

LwM2M allows for multiple instance resources such the power source
resources in the device object. These types of resources have
always been very hard to work with, and frankly were poorly
implemented.
This led to other issues where it was very hard to have
non-sequential resource instances, and each resource of this type
needed special getter / setter methods such as:
lwm2m_device_add_pwrsrc()
lwm2m_device_set_pwrsrc_voltage_mv()
Going forward, as more LwM2M objects are implemented this just
doesn't scale well.
To fix this:
- split the resource instance data out from the resource data.
This includes the data pointer information and resource
instance id.
- add resource id and resource instance id to the event callback
functions so user's can see in more detail what resources and
resource instances are being handled.
- allow generic functions like lwm2m_engine_get_*() and
lwm2m_engine_set_*() to access resource instance data.
- adjust object resource initialization macros to map resource
instances to resources at the time of object instance
creation.
- fix up the lwm2m_client as a reflection of all of these changes.

The multi_max_count is no longer used and can be removed from the

Technically, OBJ_FIELD() and OBJ_FIELD_DATA() are now the same, but
we're keeping them both for the time being. In the future, more
fields may be added to the obj_field structure and we can use the
OBJ_FIELD() macro again if that's the case.

often we can send observe notifications. We are currently using
arbitrary defaults which cannot be changed when compiled or

an observe is added.

This is a rework of the 6lo IPHC uncompression.
The uncompression now tries to work in place on the original buffer

The compressed header is pulled from the original buffer and the
buffer is preserved.
