Checking both if signing has been requested _and_ conn->encrypt can
bypass signing leading to the caller to assume that a proper signature

To fix now the code explicitly checks if SMP is enabled and in case it

Add Kconfig option to enable advanced scheduling in the
controller.
Enable non-overlapping placement of observer, initiator and
master roles in timespace. Uses window offset in connection
updates and uses connection parameter request in slave role
to negotiate non-overlapping placement with active master
roles to avoid slave roles drifting into active master
roles in the local controller.
This feature maximizes the average data transmission amongst
active concurrent master and slave connections while other
observer, initiator, master or slave roles are active in the
local controller.
Disabling this feature will lead to overlapping role in
timespace leading to skipped events amongst active roles.

HCI drivers are obliged to send HCI Command Status/Complete events
from a separate context than all other data, however the ECC wrapper
was violating this rule (sending everything from the same ECC thread).
This could lead to a deadlock if e.g. the ECC API user decides to
generate a DHKey from the same callback that it got notified of local
key-pair generation.
The obvious solution is to emit the Command Status directly from the
send function, before passing the command to be processed by the ECC
therad (through a k_fifo). However, this is not quite so simple since
bt_buf_get_cmd_complete() reuses the original command buffer, meaning
we'd loose the original parameters after sending a Command Status.
To work around this limitation with bt_buf_get_cmd_complete() we stop
passing the command buffer to the thread and instead store the
parameters in static variables and do the thread communication using
flags and a semaphore. One side effect is that only one command can be
pending at a time, however that works out fine for all of the users of
ECC.
A nice side effect of moving some things to static variables is that
we end up reducing call stack usage in the ECC thread, allowing it to
be shrunk by 180 bytes (verified to be sufficient for both ARM and
x86 boards).

Added Kconfig option to enable advanced event preparation
feature.
Enables advanced event preparation offset ahead of radio
tx/rx, taking into account predictive processing time
requirements in preparation to the event, like control
procedure handling and CPU execution speeds. Crystal
oscillator is retained between closely spaced consecutive
radio events to reduce the overall number of crystal
settling current consumptions.
This feature maximizes radio utilization in an average role
event timeslice when they are closely spaced by using a
reduced offset between preparation and radio event.
By disabling this feature, the controller will use a
constant offset between the preparation and radio event. The
controller will toggle crystal oscillator between two
closely spaced radio events leading to higher average
current due to increased number of crystal settling current
consumptions.

Atmel SAM family GMAC Ethernet driver is implementing zero-copy
networking. As a result it has to reserve a defined amount of RX
data net buffers before bringing up the interface. Since net buffer
pool is initialized by the network stack and this driver was bringing
the interface up in its initialization function the driver initialization
was performed, as a workaround, after network stack initialization. It
is not a clean solution. This patch fixes this by bringing the
interface up in interface initialization function. The driver itself
can now be initialized before the network stack is.
Tested on Atmel SMART SAM E70 Xplained board

Following changes are made:
1. Output using NET_INFO logging level. This function is not part of
automatic logging, and must be called explicitly by a user application.
But if it outputs using NET_DEBUG, then DEBUG level needs to be
enabled, and the output of this function will be drowned in logging
spam. So, let user to enable just INFO level.
2. Show entire structure of the fragment chain, *including* the head
net_buf which holds net_nbuf structure. It is numbered as -1 in the
output to preserve existing order (and not change existing size
calculations).
3. Show owning pool (and its properties, like buffer size/user_data
size) for each buffer.
4. Check for NULL pointer, e.g. for convenience of calling directly
from net_context receive callback (which will be called with NULL
on TCP peer closed connection event).
With these changes, a newcomer from one look at the output of this
function will be able to have a clear basic picture of network
buffer management in Zephyr, and recurring user will be able to
recall any details at once.
