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

k_proc was a legacy leftover that does not make any sense, since there
is no concept of a "process" in the system. Rather, that data structure
refers to a 'task control block', i.e. the representation of a task
execution context from the microkernel's point-of-view (not to confuse
with the 'struct ccs', the representation of a thread execution context,
from the nanokernel's point-of-view).

The _k_task_list was a static array generated by sysgen,
where it containing all pre-defined tasks from MDEF file.
To support private task objects (aka, defining tasks within
source files), the task list has to accommodate tasks that
are not only processed through sysgen, but also those defined
within source files.
This is done by creating a new section in binary, and all task
objects go into this section. By doing this, the task list
can still be manipulated as an array, which is required for
task group operation.

This change removes the internal number-to-function mapping
of microkernel services. Instead, function pointers are used
to specify which service to use.
This is in preparation for private kernel objects. Before this,
only kernel objects that are defined in MDEF files would have
corresponding functions included in the final binary, via sysgen
by populating an array of number-to-function mapping. This
causes an issue when a certain type of objects are all defined
with source code, and never in MDEF file. The corresponding
mapping would be deleted, and the functions are never included
in the binary. For example, if no mutexes are defined in MDEF
file, the _k_mutex_*() functions would not be included.
With this change, any usage of private kernel objects will hint
to the linker that those functions are needed, and should not be
removed from final binary.

Since the address of the new context is known before _NewContext() is invoked
(due to it being passed a properly aligned stack), there is no longer any
need for _NewContext to return the pointer to the context.
Furthermore, as a direct result of the properly aligned stack, the pointer to
the new context does not need to be passed as a separate parameter since it
will always match the passed stack pointer.

Relocates the declarations for most non-public microkernel APIs
into the main include file for such APIs (i.e. minik.h), then
eliminates the per-subsystem include files. (The per-subsystem
files don't serve any significant purpose now that the routines
comprising each microkernel subsystem have been consolidated.
In fact, there wasn't a single file that included one of these
files that didn't already include minik.h!)
Note: The channel APIs have not been consolidated yet, as they
require further cleanup. Also, one mailbox API that is used only
by the mailbox subsystem itself is moved there rather than being
placed in minik.h.

Relocates start_task() so that it appears in the main microkernel
directory, alongside its complementary routine abort_task();
this corrects a long-standing anomaly in which this microkernel-
specific routine appeared in the nanokernel portion of the tree.
With this move, the start_task.c file and its parent nanokernel/task
sub-directory no longer serve any purpose and are removed. (Note that
no changes are required for ARC architecture support, which does not
support microkernel capabilities and doesn't use this sub-directory.)

has this dependency removed, since the symbol was used for an
incomplete feature that could not be enabled. This change has

In a handful of timer-related references to LITE are not removed,

Add comments to clarify what this function actually does without needing

This function is called when a task needs to be marked as not runnable.
A task can be not runnable for a variety of reasons, which are tracked
in a bitmask defined in kernel/microkernel/include/minik.h.
Tasks that are runnable are stored in a global array, K_PrioList, that
contains a list for each task priority level. Tasks that have
