a9604bd895 unified: move basic ticks-to-ms conversion to kernel.h
The basic conversion, i.e. not handling the TICKS_UNLIMITED case, is
useful internally since the kernel is still tick-based.

8d8b2acb26 k_timer: Don't allocate dynamic timers by default
Most apps run fine with static k_timer objects.  Don't pay the cost
for the timer pool if no one asks for it.

Also turn off the allocate/free API in the header if it can't possibly
work at runtime as it's an obviously-detectable error that would
otherwise be visible only at runtime.

a5b2682ce8 init.h: use a counter when naming system devices
Avoids a build error if two or more system devices are declared

Use _CONCAT() for token concatenation to ensure the names are
properly generated, needed if any of the components are themselves
macros that need to be expanded.

757dae5b7d x86: introduce new segmentation.h header
This header has a bunch of data structure definitions and macros useful
for manipulating segment descriptors on X86. The old IDT_ENTRY defintion
is removed in favor of the new 'struct segment_descriptor' which can be
used for all segment descriptor types and not just IRQ gates.

We also add some inline helper functions for examining segment registers,
descriptor tables, and doing far jumps/calls.

ecf96d2cfa arduino 101: make factory bootloader config the default
The Arduino 101 comes with a bootloader that supports DFU
and flashing of all cores using the dfu-util package.

This changes the memory layout of the image built for the
Arduino 101 and remove previous work-arounds to allow booting,
including the version-header section in the linker script.

The bootloader expects the text section at +0x30 from the physical
load address and thus requires special treatment in the linker
script.

Other changes by Andrew Boie:
The flash size parameters were both wrong. X86 side has 192K
of flash from 0x4003000 - 0x40060000, the entire span of
sys_flash1.

ARC side is now the span from 0x40010000 - 0x40030000, 128K.

Such API has been obsolete for a long time and no one is using it

The length of the commands array in the return parameters of
the HCI Read Local Supported Commands event is 64 bytes
according to the spec. This was mistakenly set as 36 bytes due
to the fact that only 36 out of the 64 bytes currently contain
meaningful data. The actual array as received from the driver
will always be 64 bytes however, and is therefore sized
accordingly.

456c6daa9f unified: initial unified kernel implementation
Summary of what this includes:

    initialization:

    Copy from nano_init.c, with the following changes:

    - the main thread is the continuation of the init thread, but an idle
      thread is created as well

    - _main() initializes threads in groups and starts the EXE group

    - the ready queues are initialized

    - the main thread is marked as non-essential once the system init is
      done

    - a weak main() symbol is provided if the application does not provide a
      main() function

    scheduler:

    Not an exhaustive list, but basically provide primitives for:

    - adding/removing a thread to/from a wait queue
    - adding/removing a thread to/from the ready queue
    - marking thread as ready
    - locking/unlocking the scheduler
      - instead of locking interrupts
    - getting/setting thread priority
      - checking what state (coop/preempt) a thread is currenlty running in
    - rescheduling threads
    - finding what thread is the next to run
    - yielding/sleeping/aborting sleep
    - finding the current thread

    threads:

    - Add operationns on threads, such as creating and starting them.

    standardized handling of kernel object return codes:

    - Kernel objects now cause _Swap() to return the following values:
         0      => operation successful
        -EAGAIN => operation timed out
        -Exxxxx => operation failed for another reason

    - The thread's swap_data field can be used to return any additional
    information required to complete the operation, such as the actual
    result of a successful operation.

    timeouts:

    - same as nano timeouts, renamed to simply 'timeouts'
    - the kernel is still tick-based, but objects take timeout values in
      ms for forward compatibility with a tickless kernel.

    semaphores:

      - Port of the nanokernel semaphores, which have the same basic behaviour
      as the microkernel ones. Semaphore groups are not yet implemented.

      - These semaphores are enhanced in that they accept an initial count and a
      count limit. This allows configuring them as binary semaphores, and also
      provisioning them without having to "give" the semaphore multiple times
      before using them.

    mutexes:

    - Straight port of the microkernel mutexes. An init function is added to
    allow defining them at runtime.

    pipes:

    - straight port

    timers:

    - amalgamation of nano and micro timers, with all functionalities
      intact.

    events:

    - re-implementation, using semaphores and workqueues.

    mailboxes:

    - straight port

    message queues:

    - straight port of  microkernel FIFOs

    memory maps:

    - straight port

    workqueues:

    - Basically, have all APIs follow the k_ naming rule, and use the _timeout
    subsystem from the unified kernel directory, and not the _nano_timeout
    one.

    stacks:

    - Port of the nanokernel stacks. They can now have multiple threads
    pending on them and threads can wait with a timeout.

    LIFOs:

    - Straight port of the nanokernel LIFOs.

    FIFOs:

    - Straight port of the nanokernel FIFOs.

983cbe398c unified/x86: add unified kernel support for x86 arch
The x86 architecture port is fitted with support for the unified kernel,
namely:

- the interrupt exit code now calls _Swap() if the current
  thread is not a coop thread and if the scheduler is not locked

- there is no 'task' fields in the _nanokernel anymore: _Swap()
  now calls _get_next_ready_thread instead

- the _nanokernel.fiber field is replaced by a more sophisticated
  ready_q, based on the microkernel's priority-bitmap-based one

- nano_private includes nano_internal.h from the unified directory

- the FIBER, TASK and PREEMPTIBLE flags do not exist anymore: the thread
  priority drives the behaviour

- the tcs uses a dlist for queuing in both ready and wait queues instead
  of a custom singly-linked list

- other new fields in the tcs include a schedule-lock count, a
  back-pointer to init data (when the task is static) and a pointer to
  swap data, needed when a thread pending on _Swap() must be passed more
  then just one value (e.g. k_stack_pop() needs an error code and data)

- fiberRtnValueSet() is aliased to _set_thread_return_value since it
  also operates on preempt threads now

- _set_thread_return_value_with_data() sets the swap_data field in
  addition to a return value from _Swap()

- convenience aliases are created for shorter names:

  - _current is defined as _nanokernel.current
  - _ready_q is defined as _nanokernel.ready_q

- _Swap() sets the threads's return code to -EAGAIN before swapping out
  to prevent timeouts to have to set it (solves hard issues in some
  kernel objects).

- Floating point support.

Note that, in _Swap(), the register holding the thread to be swapped in has
been changed from %ecx to %eax in both the legacy kernel and the unified kernel
to take advantage of the fact that the return value of _get_next_ready_thread()
is stored in %eax, and this avoids moving it to %ecx.
