Peter Mitsis f863d66dd8 semgroup: Simplify task_sem_group_take() API family
Changes the semaphore API so that the timeout parameter must be specified
when invoking task_sem_group_take() thereby obsoleting the following APIs:
	task_sem_group_take_wait()
	task_sem_group_take_wait_timeout()
	_task_sem_group_take()

Allan Stephens 6b07c1d548 doc: Update descriptions for semaphore APIs
Standardizes appearance, corrects errors, improves readability,
and fils in gaps. Also relocates documentation for internal APIs.

Removes mention of non-existent task_sem_group_take() API from
the Kernel Primer document. The microkernel's semaphore group logic
currently allows a task to take a semaphore from a semaphore group
in a blocking manner.

Allan Stephens 7c4b9ce1f7 kernel: Eliminate the need for command packet sets
Revises microkernel semaphore sub-system to allow ISRs and fibers
to give a semaphore without having to define a command packet set.
The microkernel server now supports a 3rd command type on its
command stack, allowing a semaphore to be given in a similar manner
to the one used for the existing "give event" command type.

Allan Stephens f330d5adfe microkernel: Don't initialize packets in a command packet set
Reworks the internal design of a command packet set so that
the command packet array is split out into a separate variable
lying in uninitialized memory. This shrinks the command packet's
data section footprint to almost nothing.

Note: A side effect of this change is that it is no longer possible
to define a command packet set as a "static" variable since the
CMD_PKT_SET_INSTANCE() macro now generates two variables.

Daniel Leung 1036aee613 microkernel: Rename struct sem_struct to _k_sem_struct
This is in preparation to enable private semaphore support.
The struct needs to be moved into more visible header
so private semaphores can be declared. This also renames
according to naming convention to be private kernel
objects.

Daniel Leung 013666c964 Redefine microkernel semaphore object identifier type
The opaque semaphore object id type is now a pointer to
the associated semaphore structure, rather than an index
into the microkernel's array of semaphore structures.

This change is a pre-requisite to support for private
semaphores, which are defined in source code.

Daniel Leung 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.
