The new kernel doesn't support the thread abort handler concept,
so only the legacy API for this capability is needed.

This refactor is in preparation for making driver API structures
const.
The console driver provides a mechanism to install an input and an
output hook function. These are primarily used by the onboard
gdb-server. The output hook is entirely implemented within the
console driver.
The input hook is partially implemented in the top of the uart driver
and within the console driver. The hook function itself is installed
in the uart API structure, but is invoked only by the console driver.
Installing the hook function directly into the uart API structure
prevents the API structure being const. There are two approaches to
fixing this:
1) Implement setting of the input hook in the same way as
uart_irq_callback_set().
2) Move the input hook entirely to the console driver.
We implement the latter. This approach has two benefits, first it
removes the need for every uart driver to implement the behaviour and
second, the current placement of the callback function in the uart API
seems odd given that the callback is only invoked by the console
driver, never by a uart driver.

Fleshes out the prototype heap memory pool support
to make it fully operational. Noteworthy changes are
listed below:
Tweaks arguments to k_malloc() and k_free() to be more like
malloc() and free(). Similarly, modifies k_free() to take
no action when passed a NULL pointer.
Now stores the complete block descriptor at the start
of any block allocated from the heap memory pool. This
increases memory overhead by 4 bytes per block, but
streamlines the allocation and freeing algorithms. It also
ensures that the routines will work if the block descriptor
internals are changed in the future.
Now allows the heap memory pool to be defined using the
HEAP_MEM_POOL_SIZE configuration option. This will be the
official configuration approach in the unified kernel.
Also allows the heap memory pool to be defined using the
(undocumented) HEAP_SIZE entry in the MDEF. This is provided
for legacy reasons only.
Co-locates memory pool initialization code to keep the line
that causes memory pool initialization to be done during booting
right next to the routine that does the initialization.

This mechanism was intended to reserve space during the first pass for
certain data structures created by gen_idt, but this is unnecessary.
The only memory addresses that must be fixed between the two passes are the
locations of the interrupt stubs, which are in the .text section much
earlier than the generated data structures; they do not shift.

Ring buffer section now resides under "other" topic, since the
ring buffer type is a general purpose type (like the singly and
doubly linked list types), rather than a kernel-specific type.
Enhances ring buffer section to improve content and improve
consistency with the form used elsewhere in the Kernel Primer.
Also corrects a minor error in the ring buffer API documentation.

Ensures that all APIs which accept a timeout value wait for at least
the specified amount of time, and do not time out prematurely.
* The kernel now waits for the next system clock tick to occur before
the timeout interval is considered to have started. (That is, the only
way to ensure a delay of N tick intervals is to wait for N+1 ticks
to occur.)
* Gets rid of ticks -> milliseconds -> ticks conversion in task_sleep()
and fiber_sleep() legacy APIs, since this introduces rounding that
-- coupled with the previous change -- can alter the number of ticks
being requested during the sleep operation.
* Corrects work queue API that was incorrectly shown to use a delay
measured in ticks, rather than milliseconds.

For XIP images, in order to avoid the situation when
__data_rom_start is 32-bit aligned, but the actual data is placed
after rodata section, which may not end exactly at 32-bit border,
pad rodata section, so __data_rom_start points at data and it is
32-bit aligned.
On non-XIP images this may enlarge image size up to 3 bytes.
This is generally not an issue, since modern ROM and FLASH
memory is usually 4k aligned.
