This refactor is in preparation for making driver API structures
const.
The console driver provides a mechanism to install an input and an
output hook function. These are primarily used by the onboard
gdb-server. The output hook is entirely implemented within the
console driver.
The input hook is partially implemented in the top of the uart driver
and within the console driver. The hook function itself is installed
in the uart API structure, but is invoked only by the console driver.
Installing the hook function directly into the uart API structure
prevents the API structure being const. There are two approaches to
fixing this:
1) Implement setting of the input hook in the same way as
uart_irq_callback_set().
2) Move the input hook entirely to the console driver.
We implement the latter. This approach has two benefits, first it
removes the need for every uart driver to implement the behaviour and
second, the current placement of the callback function in the uart API
seems odd given that the callback is only invoked by the console
driver, never by a uart driver.

Moves the source code for ring buffers to the 'misc' area, since
it isn't really a central component of the kernel. (This also
aligns the ring buffer source code with its include file, which
is already under 'include/misc'.)

The Arduino 101 comes with a bootloader that supports DFU
and flashing of all cores using the dfu-util package.
This changes the memory layout of the image built for the
Arduino 101 and remove previous work-arounds to allow booting,
including the version-header section in the linker script.
The bootloader expects the text section at +0x30 from the physical
load address and thus requires special treatment in the linker
script.
Other changes by Andrew Boie:
The flash size parameters were both wrong. X86 side has 192K
of flash from 0x4003000 - 0x40060000, the entire span of
sys_flash1.
ARC side is now the span from 0x40010000 - 0x40030000, 128K.

We now allow modifier codes h, l, and z, although at the
moment they are simply dropped. This is to allow us to warn on
incorrect printk() usage by the compiler. These arguments get
promoted to int when they are passed as arguments so this
may never need to be addressed, although there may be implications
for (future) support for systems with 16-bit integers.
We still don't print 64-bit integers properly. but this is
nothing new.

Previously, exception stubs had to be declared in assembly
language files. Now we have two new APIs to regsiter exception
handlers at C toplevel:
_EXCEPTION_CONNECT_CODE(handler, vector)
_EXCEPTION_CONNECT_NOCODE(handler, vector)
For x86 exceptions that do and do not push error codes onto
the stack respectively.
In addition, it's now no longer necessary to #define around
exception registration. We now use .gnu.linkonce magic such that
the first _EXCEPTION_CONNECT_*() that the linker finds is used
for the specified vector. Applications are free to install their
own exception handlers which will take precedence over default
handlers such as installed by arch/x86/core/fatal.c
Some Makefiles have been adjusted so that the default exception
handlers in arch/x86/core/fatal.c are linked last. The code has
been tested that the right order of precedence is taken for
exceptions overridden in the floating point, gdb debug, or
application code. The asm SYS_NANO_CPU_EXC_CONNECT API has been
removed; it was ill- conceived as it only worked for exceptions
that didn't push error codes. All the asm NANO_CPU_EXC_CONNECT_*
APIs are gone as well in favor of the new _EXCEPTION_CONNNECT_*()
APIs.
CONFIG_EXCEPTION_DEBUG no longer needs to be disabled for test
cases that define their own exception handlers.

The GDB server implements a set of GDB commands, such as read/write
memory, read/write registers, connect/detach, breakpoints, single-step,
continue. It is not OS-aware, and thus provides a 'system-level'
debugging environment, where the system stops when debugging (such as
handling a breakpoint or single-stepping).
It currently only works over a serial line, taking over the
uart_console. If target code prints over the console, the GDB server
intecepts them and does not send the characters directly over the serial
line, but rather wraps them in a packet handled by the GDB client.

Introduces the following routines to provide safe access to memory:
_mem_probe()
_mem_safe_read()
_mem_safe_write()
_mem_safe_write_to_text_section()
Those routines will return an error if the memory is not accessible rather
than potentially crash.
This implementation is based on the image's boundaries; thus it allows
read/write access to the data/bss/init sections and read access only to
the text/rodata sections. All other memory is considered invalid, even
if addressable. This includes the leftover from the RAM at the end of
the image, since there is no support for using it (e.g. there is no
dynamic allocator).
