This sends out 2KB+ payload (i.e. guaranteedly more than 1 network

quickly let to a deadlock somewhere in the network stack. However
as of now, running with such payload can sustain testing with

It's possible to declare static threads that start up as K_USER,
but these threads can't do much since they start with permissions on
no kernel objects other than their own thread object.
Rather than do some run-time synchronization to have some other thread
grant the necessary permissions, we introduce macros
to conveniently assign object permissions to these threads when they
are brought up at boot by the kernel. The tables generated here
are constant and live in ROM when possible.
Example usage:
K_THREAD_DEFINE(my_thread, STACK_SIZE, my_thread_entry,
NULL, NULL, NULL, 0, K_USER, K_NO_WAIT);
K_THREAD_ACCESS_GRANT(my_thread, &my_sem, &my_mutex, &my_pipe);

The main purpose of recv_thread is to process incoming events from the
radio and also any buffered items waiting to be dispatched to the Host
and that are pending because of lack of Host buffers.
When an iteration of the recv_thread obtains a element from the radio it
needs to process it immediately, either sending it straight away to the
Host or appending it to the queue. This was not the case before this
patch, where the concurrency of a buffered packet with one coming from
the radio would cause the latter to be "dropped", causing missing
packets.

During firmware download via block-wise transfer, we can see
packets occaionally get re-transmitted (normal logic in the
pending / retry functions). However, both of these packets
end up coming through the reply handler and we should ignore
any block-wise transfer that has a current value less than
where we expect to be.
NOTE: This fixes K64F ethernet transfers where we were getting
too many packets back in the handler.

UDP packets can be lost in heavy traffic. Normally we can handle this
with pending packet processing for packets which have not been responded
to with an ACK. However, due to the time it takes for firmware to
download via CoAP, an extra level of retries should be added.
The process works like this:
Normal pending packets will try to send 3 times fairly quickly.
If that fails, then the timeout callback is called for the firmware
download process. A retry counter is incremented and the timeout
callback perform a new packet send of the block-wise transfer
packet that is missing, until the retry counter hits a limit (3)
and then the transfer is aborted.
This allows for a longer "outage" to happen during firmware transfer
and the process can still succeed.
NOTE: This patch does not fix a current bug where the pending process
is not re-sending the packets correctly, it only makes the process
more stable with a better chance to work.

When a packet expires after the pending retries we call
lwm2m_release_message() to free up resources. This includes
cleanup of the pending structure which calls net_pkt_unref on
the pending packet. This would normally free up the packet
memory. However, earlier in the pending processing we add a ref
to the packet so that normal send processing doesn't free up
the memory. This meant we were leaking packet memory every
time we had an expiration due to timeout.
Let's do an unref prior to calling lwm2m_release_message() to
make sure the packet memory is freed correctly.

Previously, firmware support wasn't initializing the retransmit work

Create an internal function lwm2m_engine_context_init() which sets

In the case of a proxy server translating HTTP -> COAP (known in
the code as "separate reply"), we were leaking lwm2m_message structures.
This was due to pending objects being cleared out during the first ACK,
and no other way of finding a matching message when the follow up packet
was received. Let's add a second match for reply to make sure we can
find our matching message resources.
NOTE: This change renames find_msg_from_pending() to find_msg() and
makes it a static function as it's only used by the lwm2m_engine.
