individually or standalone into the build subfolder.

Move this section under the kernel and alongside other core and low
level features that are tied to the kernel.

Move guides and APIs into separate directories and cleanup naming
introducing index files rather than named section files.

The phrase "object must have _k_object_init() on it at some point"
visibly misses "called".

Dynamic kernel objects no longer is hard-coded to use the kernel
heap. Instead, objects will now be drawn from the calling thread's
resource pool.
Since we now have a reference counting mechanism, if an object
loses all its references and it was dynamically allocated, it will
be automatically freed.
A parallel dlist is added for efficient iteration over the set of
all dynamic objects, allowing deletion during iteration.

Forthcoming patches will dual-purpose an object's permission
bitfield as also reference tracking for kernel objects, used to
handle automatic freeing of resources.
We do not want to allow user thread A to revoke thread B's access
to some object O if B is in the middle of an API call using O.
However we do want to allow threads to revoke their own access to
an object, so introduce a new API and syscall for that.

Adding a new kernel object type or driver subsystem requires changes
in various different places. This patch makes it easier to create
those devices by generating as much as possible in compile time.
No behavior change.

The expected order for heading levels in our ReST documents is # for H1,
* for H2, = for H3, and - for H4. Some documents snuck in without
following this guideline.

This initial batch of documentation describes policies and
mechanism related to kernel objects and system calls.
Some details on porting user mode to a new arch have been
provided in the architecture porting guide.
Thread documentation updated with some user mode consideration.
This is not the final documentation, more to come in subsequent
patches.
