Our application (posix-naive/debug) ran into segmentaion faults,
because the socket was closed between the "wait for sockets" and the
second if in the first loop. Added the check also to line 690
and 720.
The other uses of sock_ctx[i] are already checked against NULL

Some minor housekeeping prior to adding an http server

and that number will likely increase with subsequent work.
Moving them into a common directory cleans up the

Used the registry lock in the functions lwm2m_registry_lock() and
lwm2m_registry_unlock() to make the registry lockable through a public
API. If writing to multiple resources that are composite-observed,
locking will halt the main thread until every resource is written to,
ensuring that only one notify message will be sent. Updated
the documentation in lwm2m to include this addition.

Separate closing lwm2m context from closing socket. This patch is required

By default, any string or opaque data that LwM2M engine initializes
sets data lenght to same value as given buffer length for that
resource.
However, on run time, engine keeps track how much data is written
to each resource, so when reading from any resource, should only
return data that has been written there. But uninitialized resources
return the content of the whole buffer.
Fixed the problem by introducing macros INIT_OBJ_RES_LEN(),
INIT_OBJ_RES_MULTI_DATA_LEN() and INIT_OBJ_RES_DATA_LEN() that
allows you to give the amount of data existing in buffer when
the resource is initialized. This sets the data_len and max_data_len
variables correctly.
Also introduced new functions lwm2m_engine_get_res_buf() and
lwm2m_engine_set_res_buf() that distinct between data size and
buffer size. Deprecated the previous functions
lwm2m_engine_get_res_data() and lwm2m_engine_set_res_data()

Update client tx timestamp right after message is added to list
of outgoing messages. Delay between when message is generated and
sent is negligible. This will prevents bugs that appear when using

updated when message is generated.

When lwm2m_rd_client_stop() was called and immediately
followed by lwm2m_rd_client_start() it leaked the file
handle for existing socket.
Problem can be fixed when rd_client_stop() does not
move state machine to IDLE, but instead DEREGISTER
and then allow state machine to move forward.
I added a blocking wait for rd_client_stop() because
it needs to wait for proper clean up.
I also move couple of lwm2m_engine_context_close() to
set_sm_state() event handler or similarly in lwm2m_engine.c
there was couple of places where context was not properly
cleaned.

If NET_IPV4 and NET_SOCKETS_PACKET is enabled, NET_SOCKADDR_MAX_SIZE will
be bigger than the ipv4 address length.
This is a problem when DTLS is used as the address comparison will fail

This is also a problem if NET_IPV6 and NET_IPV4 is enabled and the remote
