Replaces microkernel global variable _k_sys_clock_tick_count with the
global variable _sys_clock_tick_count. This allows both the microkernel
and the nanokernel to use the same variable to track system clock ticks
instead of using two different ones.

Fixes the type of global variable _sys_idle_elapsed_ticks such that
both its nanokernel and microkernel definitions are of the same
type--int32_t.
One of the repercussions of this is that code related to the routine
_nano_sys_clock_tick_announce() does not need the application of
typecasting.

Move the files that *know* about the calling convention in use by the
compiler. The routines exposed by the files moved to the i386_sysV_abi
directory follow the C calling convention specified by the
i386_sysV_abi which is the default for GCC. The upstream GCC has been
enhanced to support the iamcu_ABI that is optimized for processors
that implement the IA MCU instruction set. This new ABI provides code,
data and stack size improvements on IA MCU based systems.
This change is the first step in adding support for the IA MCU
optimized toolchains to Zephyr OS

This allows using wildcards with kconfig files so there is no need
to include individual files within a well define tree structure.
For example, you add
source "drivers/*/Kconfig"
and all Kconfig files under drivers/ will be sourced and the order in
menuconfig will be based on the wildcard processing, not in any particular
order.
The main advantage here is that drivers and platforms become drop-ins, a platform
or a driver can be added by just placing it in the right place without having to
change system Kconfig files or Makefiles (Makefiles will be supported in other change).

In order to keep the code compatibility with Linux and Windows, the flag
O_BINARY is defined as zero when we are compiling in a Linux host. But
when compiling in a Windows host, we have to use the definition of the
flag provided by the host's includes. Currently, there is a custom macro
to identify if the host is a Windows host. This commit change that custom
macro for the macros that compilers provide to avoid defining a new one.
