Fibers initialize this back pointer to NULL as they are (by definition)
not microkernel tasks. Microkernel tasks initialize it to their
corresponding 'ktask_t'.
However for nanokernel systems, the back pointer is always NULL. This
is because there is only one task in a nanokernel system (the background
task) and it can not pend on a nanokernel object--it must poll.

We really should have more faith in the compiler, it generates
code to implement this exactly like the arch-specific assembly
versions, and on ARM is actually 4 bytes shorter.
FUNC_NO_FP used to disable the usual C preamble to update the
frame/stack pointers, which is how the sizes are still the same
or less. It's debatable how useful the occasional use of
FUNC_NO_FP is in practice since it hinders debugging and in a
production build frame pointers should be globally disabled, but
we can address that later.

Of the 3 related functions;
_thread_essential_set()
_thread_essential_clear()
_is_thread_essential()
The first two are parameter-less and always operate on
"_nanokernel.current". The last one takes a 'thread' parameter but will
operate on _nanokernel.current if the parameter is NULL. All calls to
_is_thread_essential() pass NULL!
This change makes the 3 functions consistent by removing the parameter
to the 3rd function. This should also be marginally more efficient,
though consistency was the motivation. This change corrects the doc
preamble to all 3 functions.
(These functions would probably be better as inlines. Also, the choice
of when to use wrappers seems a bit arbitrary. E.g. there's nothing
for setting/testing the "FIBER" flag.)

With most boards there's no simple way to get access to the HCI
traffic. Simultaneously these boards only have one external UART for
the console. This patch introduces a protocol which combines both
normal logs and HCI logs over a single binary protocol sent over the
console UART.
The protocol is modeled based on the btsnoop/monitor protocols used by
BlueZ, and the first tool that's able to decode this is btmon from
BlueZ ("btmon --tty <tty>").
For platforms with two or more external UARTs it is still possible to
use CONFIG_UART_CONSOLE as long as the UART devices used are
different, however on platforms with a single external UART
UART_CONSOLE should be disabled if BLUETOOTH_DEBUG_MONITOR is enabled
(in this case printk/printf get encoded to the monitor protocol).

The GDB server implements a set of GDB commands, such as read/write
memory, read/write registers, connect/detach, breakpoints, single-step,
continue. It is not OS-aware, and thus provides a 'system-level'
debugging environment, where the system stops when debugging (such as
handling a breakpoint or single-stepping).
It currently only works over a serial line, taking over the
uart_console. If target code prints over the console, the GDB server
intecepts them and does not send the characters directly over the serial
line, but rather wraps them in a packet handled by the GDB client.
