Moves the source code for ring buffers to the 'misc' area, since
it isn't really a central component of the kernel. (This also
aligns the ring buffer source code with its include file, which
is already under 'include/misc'.)

Add the REBOOT kconfig option, along with the sys_reboot() API.
This infrastructure is not enough to actually perform a reboot.
Architecture/platform code must be provided as well, in the form of a
sys_arch_reboot() function.

Introduces the following routines to provide safe access to memory:
_mem_probe()
_mem_safe_read()
_mem_safe_write()
_mem_safe_write_to_text_section()
Those routines will return an error if the memory is not accessible rather
than potentially crash.
This implementation is based on the image's boundaries; thus it allows
read/write access to the data/bss/init sections and read access only to
the text/rodata sections. All other memory is considered invalid, even
if addressable. This includes the leftover from the RAM at the end of
the image, since there is no support for using it (e.g. there is no
dynamic allocator).

The old doubly-linked list implementation had only support for very
basic operations, i.e. add at head and remove.
The new implementation is highly enhanced, allowing these operations:
- initialize list
- check if a node is the list's head
- check if a node is the list's tail
- check if the list is empty
- get a reference to the head item in the list
- get a reference to the next item in the list
- add node to tail of list
- add node to head of list
- insert node after a node
- insert node before a node
- insert node at position based on condition
- remove a specific node from a list
- get the first node in a list
The implementation is completely inline, since the operations are rather
simple and do not warrant a function call.
