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.

This trick was pioneered in Linux as the config_enabled() macro. The
madness has the effect of taking a macro value that may be defined to
"1" (e.g. CONFIG_MYFEATURE), or may not be defined at all and turning
it into a literal expression that can be used at "runtime". That is,
it works similarly to "defined(CONFIG_MYFEATURE)" does except that it
is an expansion that can exist in a standard expression and be seen by
the compiler and optimizer. Thus much #ifdef usage can be replaced
with cleaner expressions like:
if (IS_ENABLED(CONFIG_MYFEATURE))
myfeature_enable();

This code is inspired by a similar feature found in ccan[1],
that enforces that the parameter passed to ARRAY_SIZE() is
always an array and not a generic pointer. This is a slightly modified
version that will work if the macro is expanded outside of a function
body.
The check is performed by comparing if typeof(array) and
typeof(&array[0]) are of a different type. Due to the way arrays
decays to pointers in C, if one passes a pointer, the types won't be
compatible and a compile time assertion will fail.
No bugs have been found with this change, but since there's no runtime
or size overheads, there's no reason to not enable it.

This macro does two things: first, it validates that the pointer is not
NULL. Second, it validates if it's between the first and the last
element in the array.
This is useful for cases where a pool of structures are used, such as
in the network subsystem.

Use IOAPIC_EDGE instead of IOAPIC_LEVEL to fix missing interrupts.
During tests it was found that using IOAPIC_LEVEL interrupts for UART at
some points are lost.

Such helper is useful to generate a complete bit mask from a given

This patch adds a driver for a Synopsys DesignWare Ethernet MAC. The
driver uses interrupts to handle received frames, but it uses a
spinloop when transmitting to wait for the transmit descriptor to
become available. Transmission is coordinated by a fiber, so this
should not result in the system execution being blocked. Only a
single descriptor is allocated for each of the transmit and receive
directions to save memory and simplify the code. Another
simplification is that none of the offload capabilities of the
Ethernet device are used. The driver currently only supports a single
instance of the Ethernet MAC, which is consistent with the limitation
in the network stack that only a single network device is supported.

This will be useful when an implementation of a generic API requires an
int as user data when such has been defined to be a pointer.
int do_something(struct device *dev, void *user_data);
When the implementation would:
int impl_do_something(struct device *dev, void *user_data)
{
int identifier = POINTER_TO_INT(user_data);
