Instead of waiting for the retransmit timeout, retransmit as soon as
missing data is deduced based on a triple-duplicate ACK.
Increase the number of buffers in the testcase, to allow for at least 4
packets in flight to trigger the triple-duplicate ACK.

When out of order data is received, send out a duplicate ACK to notify
the sender that there is data received out of sequence, so it can
retransmit the missing section.
Also avoid sending acknowlegdement to acknowlegdement messages that are
having an out of order sequence number.

This commit clears cached random address in bt_dev when calling
bt_disable(). This change makes future calls of set_random_address()
function possible with previously used address value, after BLE stack
re-initialization. Without this change no HCI command was sent, see this
condition in set_random_address():
/* Do nothing if we already have the right address */
if (!bt_addr_cmp(addr, &bt_dev.random_addr.a)) {
return 0;
}

Additional uncontrolled delay for transmitting segack affects throughput
of the segmented messages. Though the best throughput can be achieved
with the smallest allowed values, move them to Kconfig option so that
the segack delay can be controlled by a user.

When CONFIG_KERNEL_COHERENCE=y, it's illegal to place shared
data(like ztress_context_data in this test case) on the stack,
because that memory is incoherent with respect to other CPUs
in the system.
In this specific case, it will cause PC register to load invalid
handler function pointer and crash the Xtensa processor.
Make it static.

The IEEE 802.15.4 security implementation had several severe bugs:
* A regression introduced by 6ea225e34a
(net/ieee802154: Finally removing usage of ll_reserve in L2)
introduced a buffer leak (reading/ writing beyond the end of the frame
buffer) and led the security implementation to malfunction in all but
the simplest cases (i.e. encryption/authentication: none).
* Encryption vs. authentication modes were not properly implemented i.e.
encryption was always active even if not required by the chosen
encryption level.
* Nonce endianness was not correctly handled on decryption of packets
which led to authentication failures.
* The frame counter was not checked for overflows.
* The encryption output buffer limit (out_buf_max) was not correctly set.
* Setting an invalid key mode led to a NULL pointer deref.
* We use CCM rather than CCM* as crypto.h does not provide access to
CCM*. CCM does not support encryption-only operation, though. This
condition was not checked by the code.

A new net_mgmt command and event are added for interface status,
depending on the implementation the status can be returned when polled
or an unsolicited event can be send by driver whenever there is a change

Current ztress design supports both timer context and thread
context. The timer context always uses the first element of
several global array variables like exec_cnt[] and backoff[].
But progress_timeout() is using the last element of exec_cnt[]
to calculate the progress of timer context. It is not right.

When KERNEL was not defined (unittest), the call to init_testing was
used to set a longjump target using 'stack_fail'. When triggered,
this was actually causing a segfault, because longjmp is only valid
if going directly up the stack. Since init_testing returned, it was
no longer on the stack. Instead, that logic MUST be inlined.

Normal usage for Bluetooth applications are getting close to or
already overflowing the default BT RX stack size of 1024.
For example:
- Discovery using the fixed ATT channel used 984 bytes.
- Discovery using an enhanced ATT channel used 1048 bytes,
which would lead to stack overflow using the default BT RX thread
