This patch renames the 'exit' function from newlib/libc-hooks.c to
'_exit' since this is the correct name of the newlib system call.
This patch fixes some linking errors that occur when an applications
uses abort() or assert().

On SysV ABI, the NANO_ESF parameter is passed in via the stack.
For IAMCU, this is instead expected to be in EAX.
_ExcEnter is currently using EAX to stash the return address of
the calling stub while it does a stack switch. Change it to use ECX
for this purpose, and if we are running with IAMCU place the
parameter in EAX instead of pushing it.
The output of the fault handler has been cleaned up a bit and it
now also includes the code segment.

When QEMU loads a multiboot image based on the ELF headers, it
calculates the total memory size subtracting the minimum address from
the maximum address in the program header.
While the IDT section is removed from the ELF, an empty segment in the
program header is still kept at IDT_LIST base address. Since the IDT
segment isn't contiguous with the loadable code segment, QEMU is tricked
into thinking the total memory size is larger than it really is.
To workaround this, change the address of the IDT section to the address
of the text section. This will make objcopy remove the extra segment
entirely when the IDT section is removed.
This could have been fixed in QEMU since this isn't a bug in Zephyr
per-se, but it will be easier to avoid specific QEMU versions
requirements.

This was never implemented on ARC/ARM and has been superseded
by irq_offload().
Some checks that were only done with CONFIG_LOAPIC_DEBUG fall
under the category of 'shouldn't ever happen' and have been
converted into assertions, instead of propagating return values
which are largely never checked.

This patch introduces the 'QMSI RTC device driver' which is simply a shim
driver based on RTC driver provided by QMSI BSP.
Some config options are independent of the driver implementation used,
so use a consistent name for them. In this case RTC Interrupt number and
Priority use the same config options for both the QMSI and DesignWare
drivers.
In order to enable this driver, the following options should be set:
CONFIG_QMSI_DRIVERS=y
CONFIG_QMSI_INSTALL_PATH="/path/to/libqmsi/directory"
CONFIG_RTC=y
CONFIG_RTC_QMSI=y

If we are not doing any dynamic interrupts or exceptions, we
can put the IDT in ROM and save a considerable amount of RAM,
up to 2K if the IDT is the default size of 256 entries.
The _interrupt_vectors_allocated table can also be put in ROM
if we're not using any dynamic interrupts.
We introduce a new Kconfig option to force the IDT to be in RAM
for situations where no dynamic IRQs are used, but ROM footprint
needs to be conserved.

Make the i2c_transfer() to transact messages through the I2C bus.
It is useful for I2C storage devices, as now we can send one message
containing the destination byte/block address, then send the data
in another message. There is no need to construct one continuous
data buffer to send both address and data anymore.
The drivers and sample apps have been updated to utilize updated
API when appropriate. For i2c_dw, only master mode has been updated.
Slave mode will be updated once we can adequately test it.

Simplifies the nanokernel timer API so that the timeout parameter must be
specified when invoking nano_isr_timer_test(), nano_fiber_timer_test(),
nano_task_timer_test() and nano_timer_test().
This obsoletes the following APIs:
nano_fiber_timer_wait()
nano_task_timer_wait()
nano_timer_wait()
Note that even the though the new API requires that the timeout parameter
be specified, there are currentl only two acceptable values:
TICKS_NONE and TICKS_UNLIMITED
Theoretically, the current implementation would allow one to supply a
finite positive value for the timeout and the system would wait up to
that many ticks for the timer to expire. However, it is thought that
that unnecessarily complicates the nanokernel timer model and so it is
left as an unsupported option. Should that change, then that feature
could be enabled by updating the documentation.
