In SMP mode, the idea of a single "IRQ lock" goes away. Long term,
all usage needs to migrate to spinlocks (which become simple IRQ locks
in the uniprocessor case). For the near term, we can ease the
migration (at the expense of performance) by providing a compatibility
implementation around a single global lock.
Note that one complication is that the older lock was recursive, while
spinlocks will deadlock if you try to lock them twice. So we
implement a simple "count" semantic to handle multiple locks.

Nobody should be including a compiler-specific toolchain header
like this, the generic toolchain.h shouls always be used.

These interrupts are for ISRs that need the lowest possible latency.
They do not take parameters and are installed directly in the interrupt
vector table.

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.

Most kernel APIs are now ready for inclusion in the API guide.
The APIs largely follow a standard template to provide users
of the API guide with a consistent look-and-feel.

IRQ is enabled.

We have not found any use-cases for dynamic IRQs where a static
IRQ did not also suffice. Deprecate so that we can eventually
remove from Zephyr and nontrivially decrease the complexity of
the kernel.

The app-facing interface for configuring interrupts was never
formally defined, instead it was defined separately for each arch
in their respective arch-specific header files. Occasionally these
would go out of sync.
Now there is a single irq.h header which defines this interface.
To avoid runtime overhead, these map to _arch_* implementations of
each that must be defined in headers pulled in by arch/cpu.h.
