bfa89782a8 gpio: Clean up API documentation
Fix minor issues in doxygen comments. Do not use typedefs for internal
driver API calls. The functions are declared directly in
`struct gpio_driver_api`. No functional changes.

Adds a structure of callbacks for each model instance. This allows for
more flexible model implementations, that can interact with the Mesh
stack without going through the application.

For now, only an init callback is added, replacing the init mechanism in

flag that used to be in the foundation model callbacks, but replaces
this with an inline function in access.h.

e6ffb3fdc4 spinlock: Make sure C and C++ have the same sizeof(k_spinlock) value
If CONFIG_SMP and SPIN_VALIDATE are both not defined the k_spinlock
struct will have no members. The result is that in C the sizeof
value of struct k_spinlock is 0 and in C++ it is 1.

This size difference causes problems when the k_spinlock
is embedded into another struct like k_msgq, because C and
C++ will have different ideas on the offsets of the members
that come after the k_spinlock member.

To prevent this we add a 1 byte dummy member to k_spinlock
when the user selects C++ support and k_spinlock would
otherwise be empty.

First "complete" version of Intel64 support for x86. Compilation of
apps for supported boards (read: up_squared) with CONFIG_X86_LONGMODE=y
is now working. Booting, device drivers, interrupts, scheduling, etc.
appear to be functioning properly. Beware that this is ALHPA quality,
not ready for production use, but the port has advanced far enough that
it's time to start working through the test suite and samples, fleshing
out any missing features, and squashing bugs.

34307a54f0 arch/x86: initial Intel64 bootstrap framework
This patch adds basic build infrastructure, definitions, a linker
script, etc. to use the Zephyr and 0.10.1 SDK to build a 64-bit
ELF binary suitable for use with GRUB to minimally bootstrap an
Apollo Lake (e.g., UpSquared) board. The resulting binary can hardly
be called a Zephyr kernel as it is lacking most of the glue logic,
but it is a starting point to flesh those out in the x86 tree.

The "kernel" builds with a few harmless warnings, both with GCC from
the Zephyr SDK and with ICC (which is currently being worked on in
a separate branch). These warnings are either related to pointer size
differences (since this is an LP64 build) and/or dummy functions
that will be replaced with working versions shortly.

6564974bae userspace: Support for split 64 bit arguments
System call arguments, at the arch layer, are single words.  So
passing wider values requires splitting them into two registers at
call time.  This gets even more complicated for values (e.g
k_timeout_t) that may have different sizes depending on configuration.
This patch adds a feature to gen_syscalls.py to detect functions with
wide arguments and automatically generates code to split/unsplit them.

Unfortunately the current scheme of Z_SYSCALL_DECLARE_* macros won't
work with functions like this, because for N arguments (our current
maximum N is 10) there are 2^N possible configurations of argument
widths.  So this generates the complete functions for each handler and
wrapper, effectively doing in python what was originally done in the
preprocessor.

Another complexity is that traditional the z_hdlr_*() function for a
system call has taken the raw list of word arguments, which does not
work when some of those arguments must be 64 bit types.  So instead of
using a single Z_SYSCALL_HANDLER macro, this splits the job of
z_hdlr_*() into two steps: An automatically-generated unmarshalling
function, z_mrsh_*(), which then calls a user-supplied verification
function z_vrfy_*().  The verification function is typesafe, and is a
simple C function with exactly the same argument and return signature
as the syscall impl function.  It is also not responsible for
validating the pointers to the extra parameter array or a wide return
value, that code gets automatically generated.

This commit includes new vrfy/msrh handling for all syscalls invoked
during CI runs.  Future commits will port the less testable code.
