k_alert_init() needs to set the "flags" field of its associated
work item to zero, indicating that the work item has not yet
been submitted to the system workqueue. Using the standard work
item initializer macro ensures this is done correctly.

PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.
New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.
Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

Defines an object tracing list for each kernel object type
that supports object tracing, and ensures that both statically
and dynamically defined objects are added to the appropriate list.
Ensure that each static kernel object is grouped together with
the other static objects of the same type. Revise the initialization
function for each kernel type (or create it, if needed) so that
each static object is added to the object tracing list for its
associated type.
Note 1: Threads are handled a bit differently than other kernel
object types. A statically-defined thread is added to the thread
list when the thread is started, not when the kernel initializes.
Also, a thread is removed from the thread list when the thread
terminates or aborts, unlike other types of kernel objects which
are never removed from an object tracing list. (Such support would
require the creation of APIs to "uninitialize" the kernel object.)
Note 2: The list head variables for all kernel object types
are now explicitly defined. However, the list head variable for
the ring buffer type continues to be implicitly defined for the
time being, since it isn't considered to be an core kernel object
type.

the semaphore in a non-binary way.

Event is such an overloaded and generic term (event logger, *kernel*
event logger, "protocol" events in other subsystems, etc.), that it is
confusing for the name an object. Events are kinda like signals, but not
exactly, so we chose not to name them 'signals' to prevent further
confusion. "Alerts" felt like a good fit, since they are used to "alert"
an application that something of significance should be addressed and
because an "alert handler" can be proactively registered with an alert.
