Lots of new stuff

Note that the default DEFAULT_RF24_CS_PIN on Arduino Mega (and maybe others) has changed from 10 to SS.

Relax Gitler on commit headline length (#1031)

The guide we are referring to
( https://chris.beams.io/posts/git-commit/ )
says:
shoot for 50 characters, but consider 72 the hard limit

so let Gitler consider 72 the hard limit (instead of 50).

Since we have multiple git repos, we don't want to duplicate the
guidelines in each repo. Instead, we link to the canonical source
on mysensors.org.

BCM driver: include inttypes (#983)

This makes it possible to compile the Raspberry Pi gateway on
Raspbian 9 (stretch), even without adding
--extra-cxxflags="-D__STDC_FORMAT_MACROS"
(as was suggested in
#955 but was
insufficient for remediating this problem)

The compile problem was inadvertently introduced in
2d5404d.

This change fixes the problem discussed in

Script documentation generation and UML support (#992)

Documentation is now generated by invoking a shell script
which takes care of all the plumbing.
There is now also support of inlineing PlantUML syntax with
Doxygen. This inlining takes the form of
@startuml{imagename.png}
'PlantUML specific syntax'
@enduml
The inlineing can be made in C syntax comment blocks.
Doxygen will then include the generated UML diagram when
rendering the HTML documentation.
All generated images will be placed under Documentation/img
which is the default search path for Doxygen.

Clarify TSM:ID:FAIL message (#984)

As discussed in
http://korturl.nu/gitler-is-a-stubborn-bastard-1
and numerous other forum threads, many people don't understand
that id generation is done by the controller.

Many new users start out their first MySensors network with a
gateway, a single sensor node and no controller. Since MySensors
defaults to AUTO node id, the node gets stuck on TSM:ID:FAIL,
like this:
TSM:ID
TSM:ID:REQ
TSF:MSG:SEND,255-255-0-0,s=255,c=3,t=3,pt=0,l=0,sg=0,ft=0,st=OK:

TSF:MSG:SEND,255-255-0-0,s=255,c=3,t=3,pt=0,l=0,sg=0,ft=0,st=OK:

This change adds a clarifying note about the controller in the
doxygen documentation.

• Generate Doxygen from configure

Use case: view the ./configure help text on the web.
This has been requested in
https://forum.mysensors.org/post/77751

Manually putting the help text in the forum or on mysensors.org
would lead to diverging documentation, no version management and
extra maintenance burden. This commit attempts to auto-generate
the documentation and use existing Doxygen infrastructure to
add the help text to the rest of the MySensors documentation.

Implement Jenkins pipelines as code (#948)

Jenkins has been updated with new jobs that scan and execute
Jenkinsfiles. These Jenkinsfiles encapsulates all logic for building
and validating the commits in both pull requests and merged pull
requests.

Filestructure is as follows:
.ci/Jenkinsfile - This is the main Jenkinsfile that handles normal
pull request builds as well as merged pull request
post-validation.
Any repository in the MySensors GitHub organization
can implement this file and Jenkins will pick up
and execute it automatically.
.ci/Jenkinsfile-nightly - This perform merged pull request
post-validation using the nightly builds of
the Arduino IDE to provide early compliancy
status of the MySensors library for
upcoming releases of the Arduino IDE
.ci/ - This folder contain all the auxiliary scripts executed by the
Jenkinsfiles as well

Keep Serial from being linked when disabled (#877)

Even with MY_DISABLED_SERIAL defined, the linker is still adding the
Serial object to the binary.

That's because a) the MySensors *.cpp files are actually included
into the sketch and compiled as part of it (and not compiled
separately and then linked) and b) due the the default(?) behavior of
the linker (https://github.com/arduino/Arduino/issues/4579).

Memory optimizations in signing (#874)

• Sha256 driver cosmetics

cosmetic cleanups:

• use actual define that was used to allocate the array
• remove unused file globals

• Save memory by eliminating sha256_hash array

eliminated sha256_hash array to save memory. Instead pass the
Sha256Class result pointer.

There seems to be no use for the extra sha256_hash array as it was
zeroed exactly at the same time, the Sha256Class result was invalidated
(by calling signerSha256Init)

If the result needs to stay around while another sha is calculated,
it's better to have the user taking care of this.

• Moved hmac methods and buffers to separate class

This allows saving the buffer memory if no hmac is needed ... eg. with
the public Signing API.

Let signing backend validate personalization (#873)

For soft signing, let backend handle checksum verification of
personalization data. This ensures that the backends sha256 library is
used and avoids an unnecessary instanitation of the public library.
For atsha204 signing, no checksum verification is made, just chip
locking flags.

Signing improvements package (#871)

• Signing support with MAX_PAYLOAD>32

Support in the signing backends to handle configurations
where MAX_PAYLOAD is more than 32 bytes.

Fixes #748

• Support big message signatures

Support for signing messages larger than 32 bytes.
This is not fully testable with the current version of
the library but the change would add theoretical support
for signing any sized messages.

Fixes #749

• Have gw properly indicate whitelisting preferences

If the gateway hold a signing whitelist, inform all
nodes of this requirement and not just nodes that hold
whitelists themselves.

Fixes #806

• Harden security

The flag MY_SIGNING_GW_REQUEST_SIGNATURES_FROM_ALL
has been removed. Gateway will now request signatures
from everyone by default.
In addition to this, no nodes in the network will allow
clearing of signing/whitelisting preferences by OTA
commands by default.
If the old behaviour is needed (suitable for gradual
signing roll out and development purposes) a new flag,
MY_SIGNING_WEAK_SECURITY can be set.

Fixes #807

• Signing debug messages rewritten

All signing related debug has been rewritten to
better match other core debug printouts.
Also, backends are updated to have a smaller
implementation delta.

• Simplified signing option implemented

Enable by MY_SIGNING_SIMPLE_PASSWD. Signing, and signing requirements
will be enabled, as will encryption. Whitelisting is optional.
The value provided to MY_SIGNING_SIMPLE_PASSWD is used as HMAC and AES
key. Whitelists use the first 8 bytes of the password and the ninth
byte from the node ID as serial.
Password is required to be at least 8 characters wide. It is zero
padded if it is not long enough to cover the AES (16 bytes) and HMAC
(32 bytes) keys. It is not recommended to have a password shorter than
32 bytes, and there is no need for a password longer than 32 bytes.

• Add documentation section for signing debug

• Add nRF5 encryption to simple signing option

• Restructure MySigning documentation

• Minor fixes for Linux

Enhance randomness (AVR, ESP8266, Linux, NRF5) (#845)

This commit changes the way random numbers are available
with MySensors.

The AVR platform uses a 32 Bit random seed build from a floating
analog pin. The way of the generation of this seed is FIPS 140-2
compliant.

For support MCU with a fast way to generate random data, the
hwGetentropy() command is now available to allow rapid generation
of random data.

The ESP8266 platform uses the internal random source for randomness
for hwGetentropy() and Arduino's random() function.

The NRF5 platform initializes the pseudo random number generator
from internal hardware number generator. The internal AES-ECB unit
generates random data after filling with HWRNG data by AES-CBC.

On Linux getrandom() is implemented via syscall().

signerAtsha204SoftGetNonce speed:
AVR = ~14000us (sha204Soft)
NRF51 = ~152us (AES-CBC), 1739us (old sha204Soft)
NRF52 = ~31us (AES-CBC), 183us (old sha204Soft)
ESP8266 = ~20us (RANDOM_REG32), 380us (old sha204Soft)

All Nonce results tested for FIPS 140-2 compliance successfully.

Add nrf5 platform (#830)

• Add NVRAM support

This is an EEPROM replacement based on MCU's internal Flash memory.
The NVRAM class is designed to be stateless. Each operation is
written to flash immediately.

The last 16k(nRF51)/32k(nRF52) of Flash memory are managed by the
VirtualPage class. This class allows writing a single emulated 4k
page up 40,000 times.

The NVRAM class is a log based byte-wise storage allowing up to
40,000,000 writes depending on the number of used addresses. Each
four allocated addresses from the beginning of the NVRAM reduce the
write log by one.

When first 256 bytes of the emulated storage are used, there is an
average writing capacity of 145,000 cycles per byte.

When the write log is full, the NVRAM is compressed into a new flash
page. After a new page is ready, the old page is released. This
process can take up to 4500 ms and cannot be interrupted.

The NVRAM functionality can easily be ported to ESP8266 or SAMD by
providing a Flash interface.

• Add NRF5 platform support

This is the support of the Nordic Semiconductor NRF51 (nrf51822,
nrf51422) and NRF52 (nrf52832) platform. Based on arduino-nRF5
(https://github.com/sandeepmistry/arduino-nRF5).

The included radio driver is compatible with the NRF24 devices.
Using a SoftDevice (BLE)is not supported and must be removed before
flashing MySensors with a "mass_erase" operation.
