32bb2395c2 timeout: Fix up API usage
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.

d8fa80ffd7 boards: update arduino_due to use gpio_sam driver
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.

c16bce7a6a samples, subsys, tests: Use ARRAY_SIZE() whenever possible
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.

ac74d8b652 license: Replace Apache boilerplate with SPDX tag
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.

3a8d3dd07d samples: lcd_hd44780: use unified kernel
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.

7254f1d168 samples: gpio: lcd: sample app for HD44780 LCD controller
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.
