The files will have the needed fragments to move a .config
file to either a nano or micro kernel .config. This will let us
get rid of the micro_*_defconfig/nano_*_defconfig in the future
and once the sanitychecks are adapted leaving us with a single
fragment file per platform and thus making it easier to maintain.

Due to similar padding issue as pipe, the list of task object
may not be used directly. As mentioned before, some compiler/linker
may pad the large struct. For example, compiling under gcc and
march=i686 pads the struct to 32-byte alignment (march=atom to
64-byte alignment). This causes issue with sizeof() and pointer
arithmetic because they have no idea about the padding.
When the stars align in a certain way, these task structs may be
corrupted. So add a task pointer list and use it for task
manipulation. The task list remains as it is beneficial to group
them together to take advantage of cache locality.

It was badly named: this routine initializes what cannot be done
statically, i.e. what has to be done dynamically.
We also do not have concepts of "node" anymore since the kernel is
single-node only.

When THREAD_MONITOR is enabled, not removing the fiber from the thread
list (a) would cause the list to be erroneous, and (b) would cause
corruption of the list if the fiber stack was reused to start a new
fiber (or any other usage really).

Update the documentation of _thread_exit() to reflect the fact that a
task can call it if it does so with interrupts locked. A task or another
fiber cannot preempt a fiber, so a fiber can still call _thread_exit()
without locking interrupts. If a task locks interupts first then calls
it, no fiber or other task can preempt it either.

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.
