When supporting chain PDUs, after HCI reset the first PDU
allocated did not initialize its next pointer causing use
of unallocated PDUs for chaining while a duplicate of such
PDU buffer being allocated for other states/roles. This
causes in certain cases both Extended and Periodic PDUs
having same data, the Extended Advertising PDU being
transmitted at the instant of the Periodic Advertising.

idle_rate is uint8_t, sof_cnt is uint32_t. The result is uint32_t, which
is the wrong type for 'abs'. Explicitly cast idle_rate to uint32_t,
subtract sof_cnt and then explicitly cast to int32_t and then use abs,
storing the result in another int32_t which matches the return type for
abs.
This quiets clang warnings about passing unsigned values to abs.

The img_mgmt_upload was getting into loop with requesting
offset 0 from mcumgr, when requested to re-try upload after
write fails.
Because it is not really possible to recover from write fail,
at least currently, the commit changes code to reset upload
state in a case of write error and return an error code.
Now, when write fails, an error will be returned and upload
process will be stopped and reset; upload re-try will behave
as a new upload has been requested.
Fixes#44219

This fixes sending corrupted (incomplete) packets over RTT. Additional
helper buffer has been added to ensure the complete packet before it
can be sent over RTT. Once the complete packet is collected it is sent
to the RTT control block in non-blocking manner. From now there will
be no situation that only part of the packet (e.g. header) is sent
which lead btmon to fail to parse the corrupted data.

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()

Extended logging backend API with log_backend_is_ready call which
returns 0 is backend is ready. Logging core will make sure that
all autostarted backends are ready before they are enabled.
This option allows to handle backends which are not yet ready
after init function is called (e.g. usb backend that is not plugged
in). If this is the only backend in the system, logging processing
will not start util first backend is ready.
Function for checking readiness is optional and when backend has
no such function it is assumed that backend is ready after
initialization function returns which makes this feature backward
compatible.

In the function net_tcp_queue_data. When an -ENOBUFS by
tcp_send_queued_data is returned, it throws away the whole block of size
len from the send_data. If the len is > MSS, it could happen that the
first section is transmitted, but at the second an -ENOBUFS occurs.
In that case the data is transmitted, but later on removed from the
send_data.
To circumvent this problem, check if the len + unacked_len is smaller
then the send_data_total. If so, the data can safely be removed from
send_data. Otherwise, just pretend the transmission went OK. The
acknowledgment and retransmit path will eventually take care of it.

The window full computation was corrected to use the send_total instead
of the unacked_len. This conflicted with the new polling implementation
due to the moment when these values are changed.
Move taking the tx_sem outside of tcp_send_queued_data to handle the
-ENOBUF situation properly in case called from net_tcp_queue_data.
net_tcp_queue_data removes data from the send_data in case the
transmission failed with -ENOBUF. This cause the buffer to be not full
any more.

When there was no room to transmit the a next packet to be transmitted,
the -ENOBUFS could cause the retransmission to fail.
Secondly the conn->unacked_len can be set to 0 in the retransmission
process, causing the subscribtion to the transmit timer to fail. Use the
variable send_data_total instead.
Make sure that is the send_data buffer becomes empty the send_timer is
cancelled, but make sure any pending data still keeps on being transmitted.

The function tcp_data_get tries to update the TCP receive window using
net_context_update_recv_wnd. This function graps the context lock while
the tcp_data_get is called from a situation where it already has tcp lock
is already. Transmission actions do first grab the the context lock and
try to grab the tcp lock afterwards. The combination of both can cause a
deadlock.
By taking the shortcut to directly update the tcp receive window without
going through the net context, the context lock is not required avoiding a
possible deadlock situation.
