The helper for analyzing (fiber) stack usage is in no way specific to
Bluetooth and will likely be of use to many other places as well. Move
it therefore to include/misc.

Microkernel timers are defined at compile time as a static list
but they are allocated dynamically in kernel execution.
The object tracing list will only list those timers that are
currently allocated at debug time. For this reason, timers
can be removed from the tracing list at any time.
A very simple double linked list was implemented to reduce the
complexity of the action to remove an item from the list from O(n)
to O(1) and simplify the remove implementation.

Restructure the kernel's object tracing implementation
to provide a public API that allows debug tools to use
the debug hooks easier and allows kernel developers
to extend the kernel's object tracing scope and include
new kernel objects easier.
The API provides the trace list abstraction to keep track
of different types of kernel objects. The API contains
a simple single-linked list implementation that allows
to save space and simplifies the access to the data for
debug tools such as gdb.

Introduces the following routines to provide safe access to memory:
_mem_probe()
_mem_safe_read()
_mem_safe_write()
_mem_safe_write_to_text_section()
Those routines will return an error if the memory is not accessible rather
than potentially crash.
This implementation is based on the image's boundaries; thus it allows
read/write access to the data/bss/init sections and read access only to
the text/rodata sections. All other memory is considered invalid, even
if addressable. This includes the leftover from the RAM at the end of
the image, since there is no support for using it (e.g. there is no
dynamic allocator).

This patch adds a driver for a Synopsys DesignWare Ethernet MAC. The
driver uses interrupts to handle received frames, but it uses a
spinloop when transmitting to wait for the transmit descriptor to
become available. Transmission is coordinated by a fiber, so this
should not result in the system execution being blocked. Only a
single descriptor is allocated for each of the transmit and receive
directions to save memory and simplify the code. Another
simplification is that none of the offload capabilities of the
Ethernet device are used. The driver currently only supports a single
instance of the Ethernet MAC, which is consistent with the limitation
in the network stack that only a single network device is supported.

The profiler now uses the generic ring buffer. The dropped event
count is stored in the ring buffer's value field. The data size only
refers to the extra data attached to the message and NOT any internal
representation of metadata inside the ring buffer, the event_logger
APIs now pass this information along in dedicated parameters.

This patch is based on some code contributed by Dirk Brandewie.
This is a generic data structure for queuing data in a FIFO ring
buffer. Any given data enqueued is annotated with an app-specific
type identifier, and small integral value. Use of a data pointer
is optional if the necessary information can be conveyed in the
annotations. We want all the metadata to fit in a single DWORD.
The ring buffer always contains at least one free dword in the
buffer to correctly distinguish between full and empty queues.
Concurrency control is almost nonexistent; depending on usage,
apps may want to introduce the usage of semaphores and/or mutexes
to preserve the integrity of the ring buffer or provide notifications
when data is available.
