For stream-based protocols (TCP), adding less data than requested
("short write") is generally not a problem - the rest of data can
be sent in the next packet. So, make net_pkt_append() return length
of written data instead of just bool flag, which makes it closer
to the behavior of POSIX send()/write() calls.
There're many users of older net_pkt_append() in the codebase
however, so net_pkt_append_all() convenience function is added which
keeps returning a boolean flag. All current users were converted to
this function, except for two:
samples/net/http_server/src/ssl_utils.c
samples/net/mbedtls_sslclient/src/tcp.c
Both are related to TLS and implement mbedTLS "tx callback", which
follows POSIX short-write semantics. Both cases also had a code to
workaround previous boolean-only behavior of net_pkt_append() - after
calling it, they measured length of the actual data added (but only
in case of successful return of net_pkt_append(), so that didn't
really help). So, these 2 cases are already improved.

- net_pkt becomes a stand-alone structure with network packet meta
information.
- network packet data is still managed through net_buf, mostly named
'frag'.
- net_pkt memory management is done through k_mem_slab
- function got introduced or relevantly renamed to target eithe net_pkt
or net_buf fragments.
- net_buf's sent_list ends up in net_pkt now, and thus helps to save
memory when TCP is enabled.

There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.
Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).
Though net_pkt if the new name, it still inherit its logic from net_buf.

This patch is the first of a serie that will separate completely net_pkt
from net_buf.

This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.
We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

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.

Most of the SoC and board Kconfig use the same values for
driver initialization priorities. So refactor them, and
discard duplicate ones.
The shared IRQ init priority was changed so that the kernel
default init and device init priorities can be standardized
across all SoC/boards. Same goes for DesignWare SPI driver.
This also changes the UART_CONSOLE_PRIORITY and
IPM_CONSOLE_PRIORITY to UART_CONSOLE_INIT_PRIORITY and
IPM_CONSOLE_INIT_PRIORITY, to standardize across all drivers.
Note that this does not take away the ability to override
those values. This just provides reasonable defaults such
that there is virtually no need to override.

The peripherals utilizing UART were required to register their own
ISR rountines. This means that all those peripherals drivers need
to know which IRQ line is attached to a UART controller, and all
the other config values required to register a ISR. This causes
scalibility issue as every board and peripherals have to define
those values.
Another reason for this patch is to support virtual serial ports.
Virtual serial ports do not have physical interrupt lines to
attach, and thus would not work.
This patch adds a simple callback mechanism, which calls a function
when UART interrupts are triggered. The low level plumbing still needs
to be done by the peripheral drivers, as these drivers may need to
access low level capability of UART to function correctly. This simply
moves the interrupt setup into the UART drivers themselves. By doing
this, the peripheral drivers do not need to know all the config values
to properly setup the interrupts and attaching the ISR. One drawback
is that this adds to the interrupt latency.
Note that this patch breaks backward compatibility in terms of
setting up interrupt for UART controller. How to use UART is still
the same.
This also addresses the following issues:
() UART driver for Atmel SAM3 currently does not support interrupts.
So remove the code from vector table. This will be updated when
there is interrupt support for the driver.
() Corrected some config options for Stellaris UART driver.
This was tested with samples/shell on Arduino 101, and on QEMU
(Cortex-M3 and x86).

Rename it to DEVICE_DEFINE() so that it fits in the 'device' namespace.

Rename it to DEVICE_INIT_CONFIG_DEFINE(), because (a) it was not fitting
in any namespace and (b) it is not used to declare, but rather define a
object.

The interrupt API has been redesigned:
- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
It will be used in situations where the new static irq_connect()
won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
exactly the same way as its dynamic counterpart. The old static irq
macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
generated inline with irq_connect()
ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.

This API is not being used for anything, the interrupts for UART
drivers are all being configured statically. Saves code space as
gc-sections can't tell that these APIs are unused.
Some instances where IRQ/priority information was being saved in
data structures and never used fixed.

Changes the nanokernel semaphore API so that the timeout parameter must be
specified when invoking nano_isr_sem_take(), nano_fiber_sem_take(),
nano_task_sem_take() and nano_sem_take().
This obsoletes the following APIs:
nano_fiber_sem_take_wait()
nano_fiber_sem_take_wait_timeout()
nano_task_sem_take_wait()
nano_task_sem_take_wait_timeout()
nano_sem_take_wait()
nano_sem_take_wait_timeout()

ANSI sequences may have a numbered prefix which means that the action
needs to be taken the number amount of times, e.g. "Esc[ValueA" (move
cursor forward Value number of characters). Some ANSI commands also
have two preceding values, such as Esc[Line;ColumnH (move cursor to
Line & Column).
To support these ANSI sequences we need to track a bit of extra state,
most conveniently done using a bit field. Since the ANSI parsing logic
gets a bit long at this point it's refactored into its own handle_ansi()
function.

Instead of keeping track how many characters we need to move back to
get to the original position, take advantage of the save/restore
escape sequences. This allows us to drop the extra 'i' variable from
both insert_char() as well as del_char().

Add support for forward/backward ANSI sequences and the ability to
enter new text while the cursor is somewhere in the middle of the line
rather than at the end of it. printk is introduced into the game
rather than the old write_uart() since we need to make use of the
%u format string support for creating the ANSI sequence to move
backward/forward the right number of characters.

By default, since we don't have special support for control characters
we should simply ignore them. This includes both pure (single) control
characters as well as ANSI escape sequences. The most important
control character to support for basic editing is Backspace.
The terminal creates a Delete (DEL) character by default when
Backspace is pressed. It also treats the Backspace character ('\b') as
a non-destructive backspace. To create the effect of destructive
backspace we have to send the sequence "\b \b".

To clean up the logic and prepare for more control character support,
change the behavior so that instead of treating end of buffer as a
forced line break simply stop incrementing the position variable until
getting a carriage return.

The terminal doesn't generate line feed ('\n') when pressing return,
rather only a carriage return, so we can simplify the condition for
