b981326ae9 microkernel: remove last remnants of 'process' from text
There is no concept of a "process" in the system, so remove last
mentions of that concept from free-form text (doc, comments, macro
parameter names).

044bfc60c5 build: INIT_STACKS memset fix.
This commit fixes an issue with INIT_STACKS configuration option.
k_memset is substituted by the libc memset routine to initialize a
block of memory.

93b0ced44b Order hardware and device initialization
The initialization procedures need to be called in the
following order:
- basic hardware initialization;
- devices initialization;
- hardware clock initialization, that the kernel needs to
  run the kernel server.
This way, the board initialization routines is placed
to the pure_early_init level to make sure it runs first,
all device initialization procedures run at pure_init level,
so they are initialized early enough to be used for debugging
if needed. Hardware clock initialization is placed on
nano_early_init level to make sure hardware clock is initialized
just before the kernel server starts.

ad2d29689e console: uart_console: decouple uart console init from UART init
With this, the UART console has its own initialization which is not
dependent on UART init routines.

This will allow the app to utilize all UARTs for other purposes,
instead of always reserving one for console. Future patch
will enable this choice.

Note that the console init is effectively demoted to pure_init
from pure_early_init. The UART console depends on UART being
initialized, but there is no deferred init at this point.
So this initializes the console a bit later than UARTs,
simply to make sure the UART is initialized before using it.
Once there is a mechanism for some type of deferred initialization,
the UART console init can be promoted back to pure_early.

2fd29e2667 serial: converting to new driver initialization model
This restructures the device structs and now utilizes the new
driver initialization model. This is another step towards
converting the serial driver to the new driver model.

Note that the serial driver does not initialize the hardware
unless it is being used by another driver. The configuration
of the serial port needs to be done by the driver utilizing
the port (e.g. baud rate, interrupt priority, etc.).
Therefore, some serial ports are declared but not exactly
configured.

Also note that the UART console is being initialized at
the same time as the serial port. This will be removed
in future patch, so the UART console driver will do
its own initialization.

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.

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.
