Revises the relationships between several configuration options
to support a tickless kernel capabilty. Specifically:
1) SYS_CLOCK_TICKS_PER_SEC is now always defined, so that it can
be referenced by TICKLESS_KERNEL. However, SYS_CLOCK_TICKS_PER_SEC
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.

Introduces the TICKLESS_KERNEL configuration option, which indicates
that the kernel does not support timing capabilities. This option is
enabled automatically if the system tick rate is set to zero ticks
per second.

Lowers the default value for the NUM_TASK_PRIORITIES configuration
option to 16, as typical system are unlikely to need 64 different
task priorities.

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.

1) Relocates the GDB_INFO configuration option so that it appears
in the same menu as other debugging options.
2) Revises the prompt and help text to better describe the option's
purpose and impacts.
3) Corrects an inverted depency relationship; selecting this option
now automatically enables CONTEXT_MONITOR, rather than being dependent
upon it.

This patch adds a simple HCI UART (H4) driver that currently maps to
the second UART in the system. The main intention is to use this
together with qemu for accessing the Bluetooth controller available on
the host OS side.
The H4 HCI transport protocol is perhaps the simplest of the standard
HCI transports. It consists of a single byte in the beginning of each
packet which indicates the type of the packet: HCI event, HCI command,
ACL data, or SCO data (which we don't use at the moment).

To introduce the Bluetooth stack to the tree we need some additions to
the configuration options, as well as the very basic header files. The
patch also adds a skeleton for a bt_init() function that applications
will need to call to initialize Bluetooth functionality.

When killing QEMU, we defaulted to either killall or find the first
qemu process. This intefered with parallel builds, as we might kill
some other build's qemu process.
This makes QEMU write a pidfile in the local outdir directory and kill
only that when done.
