A couple functions which are defined by the arch interface
to be non-inline, but were implemented inline by native_posix

We should be adding a compiler barrier for IP and SP
registers when we are doing syscall generation on
ARMv6-M architecture. The syscall generation itself
only does an SVC trigger; the execution returns to
thread mode and ARM does not guarantee that IP
register is preserved, when we finally get back to
the point where the syscall was invoked. The SP
also needs to be preserved for syscalls returning
64-bit results. In that case the r0 may hold a
pointer to the stack where the 64-bit result was
pushed, That is, the stack pointer may have been
changed due to the syscall, and C code needs to
know that.

Add public API function in GATT to check if a specific connection has
subscribed to the given attribute.
Without this function the application has to keep track of which
connections has subscribed using the callbacks from BT_GATT_CCC_MANAGED
since the cfg_changed callback of the CCC doesn't carry connection
context.
The other alternative is for the application to parse the information
in the struct _bt_gatt_ccc object. Although this object has structure
information available to the application the structure is marked as
internal, so the application shouldn't rely on this definition.

The struct definitions for pdpt, pd, and pt entries has been
removed:
- Bitfield ordering in a struct is implementation dependent,
it can be right-to-left or left-to-right
- The two different structures for page directory entries were
not being used consistently, or when the type of the PDE
was unknown
- Anonymous structs/unions are GCC extensions
Instead these are now u64_t, with bitwise operations used to
get/set fields.
A new set of inline functions for fetcing various page table
structures has been implemented, replacing the older macros.

Default behavior is to include __FILE__ info with all of the Zephyr
assert macros, __ASSERT, __ASSERT_NO_MSG and __ASSERT_LOC. Setting the
ASSERT_NO_FILE_INFO kconfig option, replaces the __FILE__ with an

The POSIX ARCH delegates some of the tasks which normally

To avoid changes in the kernel-arch IF propagating into

Also move arch inlined functions into the arch.h header,

In the general case, the local APIC can't be treated as a normal device
with a single boot-time initialization - on SMP systems, each CPU must
initialize its own. Hence the initialization proper is separated from
the device-driver initialization, and said initialization is called
from the early startup-assembly code when appropriate.

This patch is a preparatory step in enabling the MMU in
long mode; no steps are taken to implement long mode support.
We introduce struct x86_page_tables, which represents the
top-level data structure for page tables:
- For 32-bit, this will contain a four-entry page directory
pointer table (PDPT)
- For 64-bit, this will (eventually) contain a page map level 4
table (PML4)
In either case, this pointer value is what gets programmed into
CR3 to activate a set of page tables. There are extra bits in
CR3 to set for long mode, we'll get around to that later.
This abstraction will allow us to use the same APIs that work
with page tables in either mode, rather than hard-coding that
the top level data structure is a PDPT.
z_x86_mmu_validate() has been re-written to make it easier to
add another level of paging for long mode, to support 2MB
PDPT entries, and correctly validate regions which span PDPTE
entries.
Some MMU-related APIs moved out of 32-bit x86's arch.h into
mmustructs.h.

Randomly generating ID the first time coap_next_id() is called is more
in accordance with CoAP recommendations (see
https://tools.ietf.org/html/draft-ietf-core-coap-18, section 4.4)
"It is strongly recommended that the initial value of the
variable (e.g., on startup) be randomized, in order to make successful
off-path attacks on the protocol less likely."
Doing this in a dedicated init function is the cleanest and most
idiomatic approach. This init function is not exposed publically which
means it will be called only once, by the network stack init procedure.
