Command Status, Command Complete and Number of Complete Packets are
used for driving TX fibers (HCI and connection). Missing any of
those event will lead to HCI traffic stall.
Priority pool will be used when critical HCI event is received
or normal pool runs out of buffers. The difference with priority
pool is that buffer from it must not be passed to RX fiber and
must be freed from bt_recv.
If driver knows HCI event opcode before requesting buffer for event
it may hint HCI core about preferred pool selection.

Since Wait mode switches off automatically Fast RC Oscillator,

Nios II CPUs vary in configuration on whether they support
'mul', 'mulx', and 'div' family of instructions. The compiler
can be told to use GCC integer library routines instead if
needed.
Ideally we would just pull the configuration out of system.h,
but pulling include file #defines into the Make environment
will involve some build system work that is best left to a
later improvement.
We've decided to take this build-time approach rather than
handle unimplemented instruction exceptions, so remove the
hook in exception.S

The return value of _Swap() is often treated as a "don't care" value and thus
often ignored. However, there are cases when it is desirable to have a
meaningful return value. This meaningful value can be assigned via
fiberRtnValueSet(). To that end, a new field has been added to the coop
register struct to store this value for when _Swap() needs to return that
meaningful value.

This fixes the regression of included services in nble.
Because user_data of BT_GATT_INCLUDE_SERVICE points to the first
attribute of service to include, and the bt_gatt_attr_read uses
memcpy, the pointer to pointer is needed to copy the address contained
in user_data to the buffer.
With this patch, included services work on nble as well as Zephyr.
