This adds a new GEN_ABSOLUTE_SYM_KCONFIG() specifically for
generating absolute symbols in assembly for kconfig values.
This is needed as the existing GEN_ABSOLUTE_SYM() with
constraints in extended assembly parses the "value" as
signed 32-bit integers. An unsigned 32-bit integer with
MSB set results in a negative number in the final binary.
This also prevents integers larger than 32-bit. So this
new macro simply puts the value inline within the assembly
instrcution instead of having it as parameter.

Prevent the bt_rand function from being called before bt_enable.
Depending on the implementation of bt_rand this function cannot
be called before bluetooth has been initialized. With host supplied
crypto functions the HCI LE rand command is used for example.
The use case for calling bt_id_create before bt_enable is meant for
when the application has storage for the identity instead of the stack.
So we add the requirement that the application has to have storage
for the identity resolving key (IRK) in addition when the local
device is privacy-enabled.

Deprecate the bt_set_id_addr API function. This is merely a wrapper
for the bt_id_create function now, except an IRK cannot be given.
When CONFIG_BT_PRIVACY is enabled an IRK has to be given by the
application because the bt_rand function cannot be called before
bt_enable.

Originally the file cache used a mem_pool, but that data structure has
been deprecated and replaced by a heap that includes metadata in the
heap area. As a result attempts to allocate all blocks will fail
because some of the reservation intended for cache data is now holding
metadata instead.
It's not immediately clear how to adjust the required heap size to
support this metadata as it depends on heap chunk units and data
structures that are not visible to the application. Experimentally a
value of 24 bytes works, while smaller values do not.
Further the previous Kconfig API to configure the allocation pool is
completely inappropriate with the new heap data structure which has
such different behavior.
So: Deprecate the old Kconfig API. Add a new Kconfig option to
directly control the cache size. Infer a default cache size that
works with the old mem_pool parameters assuming a per-block overhead.
But to avoid wasted memory use the heap allocation only when the
application customizes the size, and use a slab in other cases.

Both _IRQ_VECTOR_TABLE_SECTION_NAME and _SW_ISR_TABLE_SECTION_NAME
are defined with asterisk at the end in an attempt to include
all related symbols in the linker script. However, these two
macros are also being used in the source code to specify
the destination sections for variables. Asterisks in the name
results in older GCC (4.x) complaining about those asterisks.
So create new macros for use in linker script, and keep
the names asterisk free.

Correct functioning of spinlocks requires that they be memory barriers.
Most architectures achieve this by using the GCC extended asm syntax to

Correct functioning of spinlocks requires that they be memory barriers.
With CONFIG_SMP=y this falls out as a consequence of using sequentially
consistent atomic operations to ensure all processors are locked out.
With CONFIG_SMP=n a spinlock uses arch_irq_lock/unlock(), so the barrier
behavior must come from that function.
As arch_irq_lock/unlock() delegates to irq_lock/unlock() for
documentation, document the barrier requirement there.

While using the encoded path to a device tree node guarantees a unique
identifier for the corresponding device there is a limit on the number
of characters of that name that can be captured when looking up a
device by name from user mode, and the path can exceed that limit.
Synthesize a unique name from the node dependency ordinal instead, and
update the gen_defines script to record the name associated with the
full path in the extern declaration.
Add a build-time check that no device is created with a name that
violates the user mode requirement.
Also update the network device DTS helper functions to use the same
inference for dev_name and label that the real one does, since they
bypass the real one.

With classic volatile pointer access gcc something generates
access instructions with immediate offset value, like
str w4, [x1], #4
Such instructions produce invalid syndrome in HSR register when are
trapped by hypervisor. This leads to inability to emulate device access
in hypervisor.
So we need to make sure that any access to device memory is done
with plain str/ldr instructions without offset.
