comments up to be included in the doxygen headers instead of inline.

Changes the nanokernel stack API so that the timeout parameter must be
specified when invoking nano_isr_stack_pop(), nano_fiber_stack_pop(),
nano_task_stack_pop() and nano_stack_pop().
This obsoletes the following APIs:
nano_fiber_stack_pop_wait()
nano_task_stack_pop_wait()
nano_stack_pop_wait()
Note that even though the new API requires that the timeout parameter
be specified, there are currently only two acceptable values:
TICKS_NONE and TICKS_UNLIMITED
This nanokernel option does not support CONFIG_NANO_TIMEOUTS.

It's not really scheduling a fiber, it's making it ready. So, rename it
to _nano_fiber_ready().

Adds the following generic stack routines:
nano_stack_push()
nano_stack_stack_pop()
nano_stack_pop_wait()
Those routines are convenience wrappers for invoking the task, fiber and
ISR (if applicable) specific implementations.

The term 'context' is vague and overloaded. Its usage for 'an execution
context' is now referred as such, in both comments and some APIs' names.
When the execution context can only be a fiber or a task (i.e. not an
ISR), it is referred to as a 'thread', again in comments and everywhere
in the code.
APIs that had their names changed:
- nano_context_id_t is now nano_thread_id_t
- context_self_get() is now sys_thread_self_get()
- context_type_get() is now sys_execution_context_type_get()
- context_custom_data_set/get() are now
sys_thread_custom_data_set/get()
The 'context' prefix namespace does not have to be reserved by the
kernel anymore.
The Context Control Structure (CCS) data structure is now the Thread
Control Structure (TCS):
- struct ccs is now struct tcs
- tCCS is now tTCS

Standardize on using the irq_lock/irq_unlock (non-inline) symbols
everywhere.
The non-inline versions provide absolutely no benefits, so they will be
removed in a subsequent commit, and the inline versions will have their
_inline suffix removed.

1) Renames routine to conform to kernel naming conventions.
2) Relocates routine declaration to include files for
non-public nanokernel APIs.
3) Relocates routine definition so that it resides with the
nanokernel's other fiber manipulation routines.
4) Eliminates an unnecessary argument to the routine.

These APIs no longer serve a useful purpose; there removal helps

Append '_non_preemptible' to _fifo_put, _lifo_put, _sem_give and
_stack_push.
The original names do not convey the fact that these routines are
usable only by fibers and ISRs because they do not invoke a context
switch if they cause a fiber to become ready.

Moves all files in this sub-directory up one level, to the main
nanokernel source directory, then deletes the sub-directory itself.
This change means that all nanokernel source files (with the
excecption of its include files) are now in the main nanokernel
source directory, which is a more intuitive arrangement.
