fe7aa3f4fa misc: Allow flash image size to be constrained
The CONFIG_FLASH_LOAD_OFFSET allows the zephyr image to be placed at
an offset from the start of flash.  This is useful for situations,
such as with a bootloader, to allow the image to not occupy the very
beginning of flash.

Complement this by adding a CONFIG_FLASH_LOAD_SIZE config, that can
constrain the size of the flash image.  With the default of zero, the
behavior is as before, with the image allowed to occupy the rest of
the flash.  It can also be defined to a non-zero value which will
constrain the image to occupy that many bytes of flash.

Although this is defined generally, it is currently only supported on
cortex-m targets.

f8c9439908 net: if: Reshuffle fields in net_if and related structs
This does not save any space but sets the fields in the
structs in more natural order. Move IPv6 related
fields in net_if into internal ipv6 struct so that all
IPv6 fields are located inside one struct. Same thing
is done for IPv4 fields which are now located inside
IPv4 internal struct in net_if.

There is no functionality changes by this commit.

e7391e3068 gpio: Add gpio_mmio32 driver to access basic 32-bit i/o registers
It is envisaged that this will be used by SoC or board code to make
available fixed purpose memory-mapped i/o registers to the rest of the
system which normally expects to use GPIO devices, e.g. for driving chip
select lines, LEDs or reading button states.

As such, the driver code doesn't provide a kconfig based configuration
mechanism, instead SoC/board code can hard-wire the devices it wants
with something simple like:

GPIO_MMIO32_INIT(misc_reg1, "MISC1", 0x12345678, 0xffffffffu)

Then, for example, if bit N of the register at 0x12345678 is wired up as
an SPI device chip select line, the SPI driver could be configured to
use pin N of the "MISC1" GPIO driver and not need any other board
specific code.

542c2b93d0 subsys: console: Add pull-style console API support.
This change introduces console_getchar() and console_getline() API
calls which can be used to get pending console input (either one
char or whole line), or block waiting for one. In this regard, they
are similar to well-known ANSI C function getchar/gets/fgets, and
are intended to ease porting of existing applications to Zephyr, and
indeed, these functions (shaped as an external module) are already
used by few applications.

The implementation of the functions is structured as a new "console"
subsystem. The intention is that further generic console code may be
pulled there instead of being in drivers/console/. Besides the
functions themselves, initialization code and sample applications
are included.

At this time, there're may limitations of how these functions can
be used. For example, console_getchar() and console_getline() are
mutually exclusive, and both are incompatible with callback
(push-style) console API (and e.g. with console shell subsystem
which uses this API). Again, the intention is to make a first step
towards refactoring console subsystem to allow more flexible
real-world usage, better reusability and composability.
