This patch introduces the Connect API which initiates session
connection first. If session is already there with the peer
then it has to reuse it and initiate DLC (which will be done
in the subsequent patch) since there can be only one session
per device.

Oversight. These functions are used extensively in the kernel guts, but
are also supposed to be an API.
k_sched_lock used to be implemented as a static inline. However, until
the header files are cleaned-up, and everything, including applications
get access to the kernel internal data structures, it must be
implemented as a function. To reduce the cost to the internals of the
kernel, the new internal _sched_lock() contains the same implemetation,
but is inlined.

Updates x86 floating point support to reflect changes that have
been made in recent months.
* Many, many, many cosmetic changes (mostly revisions to comments).
* Elimination of unnecessary function aliases that were needed
to support the task and fiber versions of certain APIs.
* Elimination of run-time code to enable a thread's "FP regs"
option bit if the "SSE regs" option bit was set. The kernel
now recognizes that the thread is using the FPU as long as
either option bit is set. (If the thread has both option bits
enabled this is the same as if only the "SSE regs" bit is set.)

USB class drivers may need to offload some work from
upcall interrupt context to a background fiber. This
requires some way to defer taking more data from host
till the offloaded work completes. Two APIs are added to
achieve this.
Further USB class drivers sometimes need to set STALL condition
on end-points to signal errors to host.These too are
added.

This patch removes "FAT" from files names, config names and
symbol names so as to avoid confusion, when other modules use
them in a more generic way.
Also flash_disk_access.c and ram_disk_access.c now exports generic
disk_access symbols as defined in include/disk_access.h rather
than FAT specific ones in fs/fat_diskio.h. Thus modules like
USB which need to use disk_access interface is not dependent
on symbols from ELMChan FAT module. Also fat_diskio.h
is removed.
Further the shim between ELM chan and Zephyr is modified as
per these changes.

Making a reference to the common work queue code should not necessarily
drag in the system workqueue, since it is possible to use a workqueue
that is not the system workqueue. This is done by moving the system
workqueue into its own code module.
Moving the system workqueue to its own code module allows removing the
NANO_WORKQUEUE and SYSTEM_WORKQUEUE kconfig options, and compiling the
common workqueue code and system workqueue all the time. They are only
linked in the final image if a reference to them exist, same as the
other kernel modules.

QMSI 1.3 natively supports restoring the SoC and peripherals
after sleep.
The Zephyr Power Management shim layer is updated
in order to support QMSI functions.
The following functions have been added:
void _sys_soc_set_power_state(enum power_state);
void _sys_soc_power_state_post_ops(void);
In order to fully support deep sleep, the function
_sys_soc_set_power_state now support saving and
restoring CPU context and returns to the application.
_sys_soc_set_power_state function also abstracts
QMSI cpu states and enable the application to choose
between C1/C2 or C2LP states.
The QMSI power states are mapped as follows:
SYS_SOC_POWER_STATE_CPU_LPS -> power_cpu_c2lp
SYS_SOC_POWER_STATE_CPU_LPS_1 -> power_cpu_c2
SYS_SOC_POWER_STATE_CPU_LPS_2 -> power_cpu_c1
SYS_SOC_POWER_STATE_DEEP_SLEEP -> power_soc_deep_sleep
SYS_SOC_POWER_STATE_DEEP_SLEEP_1 -> power_soc_sleep
The following functions have been removed:
void _sys_soc_set_power_policy(uint32_t pm_policy);
int _sys_soc_get_power_policy(void);
FUNC_NORETURN void _sys_soc_put_deep_sleep(void);
void _sys_soc_put_low_power_state(void);
void _sys_soc_deep_sleep_post_ops(void);
Those changes are propagated to the samples.
All calls to QMSI are removed.

Defines an object tracing list for each kernel object type
that supports object tracing, and ensures that both statically
and dynamically defined objects are added to the appropriate list.
Ensure that each static kernel object is grouped together with
the other static objects of the same type. Revise the initialization
function for each kernel type (or create it, if needed) so that
each static object is added to the object tracing list for its
associated type.
Note 1: Threads are handled a bit differently than other kernel
object types. A statically-defined thread is added to the thread
list when the thread is started, not when the kernel initializes.
Also, a thread is removed from the thread list when the thread
terminates or aborts, unlike other types of kernel objects which
are never removed from an object tracing list. (Such support would
require the creation of APIs to "uninitialize" the kernel object.)
Note 2: The list head variables for all kernel object types
are now explicitly defined. However, the list head variable for
the ring buffer type continues to be implicitly defined for the
time being, since it isn't considered to be an core kernel object
type.

Enhance the linker script so that all statically-defined kernel
objects of a given type are co-located.
Note 1: This capability is needed so that static kernel objects
can be added to the associated object tracing list. (Some kernel
object types are already co-located to permit the kernel to do
other initialzation on statically-defined objects.)
Note 2: A follow-up commit is needed to ensure statically-
defined kernel objects are placed in the sections referenced
in the linker script.
Note 3: The legacy script info remains for now to allow
applications using the microkernel or nanokernel to continue

Several legacy API macros had the format:
#define some_legacy_api(<parameters>) other_api(<same parameters>)
This prevents passing 'legacy_api()' as a function pointer. Remove the
parenthesis where possible and instead use the format:
#define some_legacy_api other_api
This allows passing 'legacy_api' as a function pointer by having the
preprocessor resolve it to 'new_api' directly.
