We may soon want to have a _wait() variant of bt_buf_get, so to avoid
the number of 'get' function growing too large consolidate the
existing get() and get_reserve() functions into a single one. The new
consolidated function also takes the type as input parameter so that
we know this from the very start and thereby plan for the split into
multiple buffer pools.

We'll soon want to have dedicated pools for outgoing and incoming ACL
data. To know from which pool to get and put the buffers each buffer
should contain enough information to distinguish the two types. This
patch splits the old BT_ACL type into two new BT_ACL_IN & BT_ACL_OUT
types.

Allows the number of task priority levels supported by the micro-
kernel to be configured, rather than fixing this value at 64.
Setting NUM_TASK_PRIORITIES to N provides support for task
priorities 0 (highest priority) through N-1 (lowest priority).
The lowest priority is reserved for the kernel's idle task.
This enhancement allows system designers to significantly reduce
the size of the microkernel's task priority queues by eliminating
unneeded queues. In systems requiring only a few task priorities
over 500 bytes can be saved.
