Kari Argillander a2f1d6959d Make most of functions const correct (#714)
* Make most of the functions const correct

Used clang-tidy and sonarlint to help find places where const could
pretty easily applied. Also lot of hand work.

This commit does not yet touch handlers and typedefs of those.

* Fix Arduino uno handler_who_is() has extra parenthesis

For some reason there is extra parenthesis. Remove it this is more
likely buildable.

* Bugfix/bacapp: Fix uninitilized array_index

We have changed bacapp_snprintf_value() to be const correct. After that
we got

```
/home/runner/work/bacnet-stack/bacnet-stack/src/bacnet/bacapp.c:3183:27: warning: 4th function call argument is an uninitialized value [core.CallAndMessage]
                ret_val = bacapp_snprintf_weeklyschedule(
                          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 warning generated.
```

So analyzer could now spot that we do not actually initilize array_index
at all. Fix this by setting array_index to zero. Note that I actually do
not know if zeroing is right thing to do here. I choose zero as if this
has worked before it is most likely that it will work with zero value.

* cmake: Add and ignore Wwrite-strings compiler option

Wwrite-strings helps find places where const correctness is broken.

Example it will warn about these

```C

void func1(char* str);

func("test") /* "test" is const so we should not pass it to func1().

char* func2()
{
  return "test"; /* func2() should return const char*.
}
```

We still need to ignore it as not all are fixed but let's add it already
so we remember that it should be opened at some point.

Kari Argillander 0177c59f4a Use pre-commit and editorconfig (#753)
* Add editorconfig and pre-commit config

Editorconfig is widly used and supported file. It says basic things how
files should be formatted.

pre-commit is tool which can automatically check some basic checks like
code formatting everytime someone makes commit. This can also be used in
CI to run these things. Then it is very easy to do same things locally
as in CI. This also makes easy to select clang-format version so
everyone is using same one.

* clang-format: Ignore folders where are external code

We should not format external code. Add clang-format files to exclude
those. We should move external code always to example external/ folder
so we can exclude those more easily.

* clang-format: Remove custom zephyr/.clang-gormat

This clang-format file where introduces before our root clang-format. It
does not make sense anymore as we have root clang-format. Removing this
will unifie formatting in whole repo.

* clang-format: Add couple new rules

Add couple new formatting rules.

Always align const to left side. We did have only one place where it was
right side so this make sense as it is already rule for us.

I choose also insertbraces becuase when I run this I notice that we have
lot of multiline code without braces. So very error prone places. This
will take error possibility away. Repo also always use braces even with
single line statments so this does not matter much.

* ci: Add pre-commit validation

Validate pre-commit in CI.

* format: Convert spaces to tabs in Makefiles

Makefile normally use tabs. We enforce that with editorconfig. Fix
couple places where spaces where still in use.

Kari Argillander 599033b7b0 Move some external files to external/ folder (#744)
It is lot easier to work with automatic formatters if we have external
files in different folder. For some tools we can example just exclude
external all together.

Kari Argillander 369da70f2a Strip tabs and trailing white spaces, and fix end of files (#748)
* format: Strip trailing whitespaces

We want to get rid of trailing whitespaces completly as they make just git
noice. Much better to start using automated tools to get rid of them once and
not getting them back again. This way git history will be cleaner and review
easier.

Commit was generated with:

    pre-commit run --all-files trailing-whitespace

* format: Files should have exactly one new line end of them

It is good practice that every file has one new line. It is not now days so
mandatory but it also is not nice if file has lot of newlines end of it. We will
use pre-commit which takes automatically care about this so let's fix all.

Commit was generated with:

    pre-commit run --all-files end-of-file-fixer

* format: Convert tabs to spaces

Project mostly use spaces over tabs. When mixing tabs and spaces this usually
makes formatting issues and also when changing those in commits it will make lot
of git noise. We will force spaces most of the time and use pre-commit to fix.

Commit was generated with:

    pre-commit run --all-files remove-tabs

Kari Argillander 9e0657424e Prepere repo so we can run auto formatters (#747)
* clang-format: Ignore javascript files

Ignore javascript files. Clang-format is not very good formatter for
javascript files anyway. If we ever need javascript formatter we should
use Prettier.

* clang-format: Ignore some lines in sources

Couple things get formatted really funky if we let clang-format format
those. Just ignore those locally.

* zephyr/tescase.yaml: Fix yaml syntax

pre-commit hook check-yaml did found out that there are two skips.
Remove another as this is not right syntax.

* Fix repo contains unicode replacement chars

When running pre-commit text-unicode-replacement-char it founds that
there is couple unicode replacemnt chars. Remove and replace these.

* Convert some tabs to spaces manually

We will soon auto format tabs to spaces. How ever it could not do couple
thing so fix those by hand first.

* Make files with shebang executables

It is good habit that if file has shebang then it is marked executable.
These where found with pre-commit check-shebang-scripts-are-executable
checker.

Kari Argillander cb243c36a8 Improve SPDX identifier coverage (#716)
* Change MIT license texts to SPDX-License-Identifier

SPDX-License-Identifier is much easier to understand and grep than
license text so use that instead.

* Change GPL exception license texts to SPDX-License-Identifier

SPDX-License-Identifier is much easier to understand and grep than
license text so use that instead.

* Change misc license texts to SPDX-License-Identifier

There are some external code in repo which are not licenses as most of
the stuff in this repo. We still want every file to have SPDX identifier
to easily grep licenses.

* Add currently used license files

Even though Bacnet-Stack is using SPDX identifiers we still need to give
those license files with source. For this reason add all license files
to license/ folder.

SPDX has also files which would make same thing but this is style which
example Linux kernel is using and it is quite clear so I choose that one
for now.

I choosed not yet bring CC-PDDC as that is not right license for those
files.

Steve Karg 1f591db6e7 Feature/mstp zero config option (#564)
* Added a MS/TP zero-config (automatically choose an unused MAC address) using an algorithm that starts with MAC=64 and waits for a random number of PFM (minimum of 8 plus modulo 64) before attempting to choose a MAC sequentially from 64..127. The confirmation uses a 128-bit UUID with the MSTP Test Request frame. The modifications are in src/bacnet/datalink/mstp.c and src/bacnet/datalink/dlmstp.c modules enabling any device to use zero-config if enabled. A working demonstration is in the ports/stm32f4xx for the NUCLEO board. Complete unit testing is included.  Options include lurking forever (wait for a router or another master node before joining) or lurking for a minimum time (enables self forming automatic MAC addressing device nodes).
