Anas Nashif 2dc4e270b2 doc: kernel: flatten kernel docs and add API references
Instead of having kernel APIs documentated in a separate page, move the
API references to the object pages and have everything in one place.

Remove the intermediate category page and list all section under the
kernel directly.

Sebastian Bøe 1526070082 cmake: Use a variable for 'zephyr_prebuilt'
There is an effort underway to make most of the Zephyr build script's
reentrant. Meaning, the build scripts can be executed multiple times
during the same CMake invocation.

Reentrancy enables several use-cases, the motivating one is the
ability to build several Zephyr executables, or images, for instance a
bootloader and an application.

For build scripts to be reentrant they cannot be directly referencing
global variables, like target names, but must instead reference
variables, which can vary from entry to entry.

Therefore, in this patch, we replace global targets with variables.

Flavio Ceolin aecd4ecb8d kernel: Change k_poll_signal api
k_poll_signal was being used by both, struct and function. Besides
this being extremely error prone it is also a MISRA-C violation.
Changing the function to contain a verb, since it performs an action
and the struct will be a noun. This pattern must be formalized and
followed and across the project.

MISRA-C rules 5.7 and 5.9

Rajavardhan Gundi 1e6adba9ef drivers/interrupt_controller: Introduce multi-level interrupt support
In a scenario where a platform harbours multiple interrupts to the
extent the core cannot support it, an interrupt controller is added
as an additional level of interrupt. It typically combines several
sources of interrupt into one line that is then routed to the parent
controller.

Chunlin Han e9c9702818 kernel: add memory domain APIs
Add the following application-facing memory domain APIs:

k_mem_domain_init() - to initialize a memory domain
k_mem_domain_destroy() - to destroy a memory domain
k_mem_domain_add_partition() - to add a partition into a domain
k_mem_domain_remove_partition() - to remove a partition from a domain
k_mem_domain_add_thread() - to add a thread into a domain
k_mem_domain_remove_thread() - to remove a thread from a domain

A memory domain would contain some number of memory partitions.
A memory partition is a memory region (might be RAM, peripheral
registers, flash...) with specific attributes (access permission,
e.g. privileged read/write, unprivileged read-only, execute never...).
Memory partitions would be defined by set of MPU regions or MMU tables
underneath.
A thread could only belong to a single memory domain any point in time
but a memory domain could contain multiple threads.
Threads in the same memory domain would have the same access permission
to the memory partitions belong to the memory domain.

The memory domain APIs are used by unprivileged threads to share data
to the threads in the same memory and protect sensitive data from
threads outside their domain. It is not only for improving the security
but also useful for debugging (unexpected access would cause exception).

Andrew Boie d26cf2dc33 kernel: add k_thread_create() API
Unline k_thread_spawn(), the struct k_thread can live anywhere and not
in the thread's stack region. This will be useful for memory protection
scenarios where private kernel structures for a thread are not
accessible by that thread, or we want to allow the thread to use all the
stack space we gave it.

This requires a change to the internal _new_thread() API as we need to
provide a separate pointer for the k_thread.

By default, we still create internal threads with the k_thread in stack
memory. Forthcoming patches will change this, but we first need to make
it easier to define k_thread memory of variable size depending on
whether we need to store coprocessor state or not.
