Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build
$ make

This should clear up some of the confusion with random number
generators and drivers that obtain entropy from the hardware. Also,
many hardware number generators have limited bandwidth, so it's natural
for their output to be only used for seeding a random number generator.

Per ZEP-1958, Phase 2 of adding CC3220sf LaunchXL support,
was to "deprecate the CC3200 launchxl support in Zephyr
(redundant to the CC3220)."
Effectively, the CC3220 SOC replaces the CC3200.
This patch removes the following:
* the imported CC3200 SDK
* CC3200 SOC, board, DTS files.
* adjusts other files where cc3200 was mentioned.
Also, it fixes explicit references to CC3200 in generic
CC32xx driver files.

Previously, calling NVIC_SetPriority(IRQn_Type irqn, ....) with
the NWP interrupt number of 171 caused a hard fault during a
subsequent svc #0 instruction during _Swap().
GNU compiler is generating a bit extension instruction (sxtb) which
converts a positive IRQ value argument to a negative value when
casting to the CMSIS IRQn_Type enum parameter type.
This generates a negative index, which then writes to an SCB
control register instead of NVIC register, causing a hard
fault later on.
This issue only occurs when passing interrupt numbers > 0x80
(eg: 171 (0xab) for the NWP) to the CMSIS NVIC apis.
The solution here is simply to redefine IRQn_Type to be an
unsigned 32 bit integer, while redefining the CMSIS IRQn_Type
enum definitions for interrupts less than zero.

This leverages the CC3220 SDK driver peripheral library in ROM,

As part of the transition to Device Tree, a temporary
HAS_DTS configuration variable, and a .fixup file per board
with symbol aliases were added.
This patch removes the cc32xx related fixup file
definitions, except for those used additionally outside
the cc32xx drivers.
Since cc32xx has DTS files, and since HAS_DTS will always be true,
it also removes the 'if !HAS_DTS' blocks from the cc32xx Kconfig
files.

Move back to getting the number of IRQs from Kconfig. We do this
because the number of IRQs should really just be determined by scanning
the device tree and figuring out the highest IRQ value used.

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.

Previously, CC3200 drivers had two options to use the peripheral
driver library APIs:
1) Build driverlib SDK files in Zephyr, in ext/hal/ti/cc3200/*
2) Link directly with the driverlib.a, from an externally installed
TI CC3200 SDK.
A new option is added to replace option 2), and is now the default:
3) Use the driverlib functions already provided in ROM.
This enables a savings in code size, which will depend on the
types of device drivers configured and the number of SDK
APIs actually used.
A rom_report build of the shell sample application showed
a savings of about 2kb in code space using this new config option.

Though Cortex-M4 could optionally have a floating point unit,
the MCU in the cc3200 in fact does not have an FPU.
Enabling CPU_HAS_FPU caused applications built with CONFIG_FLOAT=y
to crash during an early call to enable_floating_point().
This patch was validated by running microPython, which is one
such application.

New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL

Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
