0dcad8331b clarify use of term 'context'
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

bed144b179 microkernel: rename k_proc to k_task
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).

a73af53186 timers: prevent duration of 0 in timer_start/restart
Basically, this does not work anymore:

  task_timer_start(<timer>, 0, X, <sem>);

since it does not make much sense to have a timer with an expiry of 0
ticks. The code internally was setting the duration to be equal to the
period anyway. So, to achieve the same behaviour, do this:

  task_timer_start(<timer>, X, X, <sem>);

This has the positive side-effect of removing a small block of logic
that was handling the cases where duration was 0.

c1f9fd888d irq: make utility functions private
irq_handler_set, irq_priority_set and irq_disconnect have been made
private by prepending an underscore to their names:

	irq_handler_set -> irq_handler_set
	irq_priority_set -> irq_priority_set
	irq_disconnect -> irq_disconnect

The prototypes have been removed from header files when possible, and
extern statements used in C code where they were called.

_irq_priority_set() for ARM is still in the header file because
IRQ_CONFIG() relies on it.

87564a4602 pipes/mailboxes: rename functions using mem blocks

  task_mbox_data_get_async_block_wait_timeout ->
       task_mbox_data_block_get_wait_timeout

Previous names, focusing on 'async', were misleading, because:

- some of those APIs can be used synchronously as well
- other APIs can also do asynchronous transfer, and don't have 'async'
  in their names
- the key concept of these APIs is that they use memory pool blocks
  rather than raw data buffers.

815d64522f microkernel: put pipe pointer list into its own binary section

where it containing all pre-defined pipes from MDEF file.

source files), the pipe list has to accommodate pipes that
are not only processed through sysgen, but also those defined

This is done by creating a new section in binary, and all pipe
pointers go into this section. By doing this, the pipe list
can still be manipulated as an array. The reason behind
putting the pointers to pipe, instead of the pipe objects
themselves, is that some compiler/linker may pad the large pipe
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. So use pointers here to
prevent padding.

Since a couple structs have to be moved anyway, so
do the moving and renaming here too (contrary to what
have been done in the past, with separated patches).

74c8852d05 microkernel: remove kernel service dispatch table
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.

d2857404f5 Kconfig: fix SYS_CLOCK_HW_CYCLES_PER_SEC dependencies
Fixes the SYS_CLOCK_HW_CYCLES_PER_SEC Kconfig option dependencies such that
it can be overridden by a modified platform configuration file.  This is
particularly important for the LOAPIC timer driver as
SYS_CLOCK_HW_CYCLES_PER_SEC is dependent upon the target's CPU/bus frequency.

a88cd0fc34 init: Split pure_init into pure_init_{early,late} levels
Split the pure init level into two phases this allows for easier
migration of the nano kernel init process without resorting to naming
or link order to force the ordering of functions at pure init
time. The need for change was discovered while moving the system
timers to be initialized by the init system.  The base timer driver
(eg. HPET) must be initialised prior to the system clock being enabled
both of which need to happen before nano-kernel init.

Most of the timeout queue interface is contained within timeout_q.h.
However, this file should never be included directly: rather, the
wait_q.h file is to be included instead, which itself provides NOOP
abstractions for some timeout functions when timeouts are not enabled in

ad71ba6fa1 Ensure k_args fields are properly aligned and packed
The size of the k_args strcture must be equivalent to ...
    CMD_PKT_SIZE_IN_WORDS * sizeof(uint32_t)

This is complicated by the fact that not only do different compilers treat the
size of 'bool' and 'enum' types differently, they may also pad structures
differently.  Both of these differences have direct impacts on the k_args
structure.  To work around this, the k_args fields 'alloc' and 'Comm' are
forcibly aligned to a 4-byte boundary, while the rest of the k_args structure
is packed.

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.
