The buffer handling code is quite large and will continue to grow. As
it's not strictly HCI core material it's better to just manage it in a
separate file. This patch moves the code to include/bluetooth/buf.h
and net/bluetooth/buf.c.

This patch adds a new bt_conn struct which abstracts the details of an
connection. Each connection has two fibers: one for incoming and
another for outgoing data. For now only one connection is supported.
The patch also adds a basic L2CAP header definition so that fragmented
ACL packets can be properly parsed.

Revises the nanokernel footprint benchmark project so that the
minimum x86 configuration explicitly excludes support for the
system timer. (This doesn't actually save any memory, since timer
support was already being excluded; however, the project now makes
this lack more apparent, and does it the same way as the minimum
microkernel benchmark project does it.)

is forced to 0 when there is no timer interrupt support.
2) NUM_TIMER_PACKETS is now forced to 0 in a microkernel system
when TICKLESS_KERNEL is enabled.
3) TIMESLICING is now disabled when TICKLESS_KERNEL is enabled.

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.
