Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them. Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:
+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
values for equality (e.g. with K_FOREVER or K_NO_WAIT).
+ Adding a k_msleep() synonym for k_sleep() which can continue to take
integral arguments as k_sleep() moves away to timeout arguments.
+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
generate timeout arguments.
+ Removing the usage of K_NO_WAIT as the final argument to
K_THREAD_DEFINE(). This is just a count of milliseconds and we need
to use a zero.
This patch include no logic changes and should not affect generated
code at all.

Convert to the new API, using raw access since there is no Device-Tree
definitions for this particular sample.

Re-run with updated script to convert integer literal delay arguments to
k_sleep to use the standard timeout macros.

Update configuration of arduino_due board to use a common gpio_sam
driver rather than sam3x specific gpio_atmel_sam3. The gpio_atmel_sam3
driver is going to be deprecated.

move misc/printk.h to sys/printk.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

The ARRAY_SIZE() utility macro will actually test the parameter types,
and ensure that it is only called with arrays, and not arrays decayed
to pointers.
Changes were performed with a simple Coccinelle script.

The files for the Arduino Due needed to be updated to use the new
configuration when the SoC moved from the atmel_sam3 directory to
the atmel_sam/sam3x directory.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Use unified kernel for lcd hd44780 app.
Some delays were rounded up to multiples of millisecond, since
k_sleep only takes multiples of millisecond. Based on the lcd
datasheet, this should not cause any problem.
updated some comments based on what the code is actually doing.

Display text strings on parallel interfacing HD44780 based
generic LCD controller using GPIO pins to interface with
Arduino Due(SAM3). HD44780 is a popular controller and an
example can help using gpio pins in parallel with it. I
have tested it on JHD20x4 LCD panel for 4Bits & 8Bits
configuration. The code has been made generic so that user
can modify quite a few options.
