[WIP] Add syntax check for rust and C\C++ code (#108)
* proof of concept

* fix syntax for rust and add auto fix syntax

* fix syntax for C

* fix bug with files owner

* add information to wiki

* try to add ci

* format code from master

* even more format fixes

* change docker to docker-compose

* Exclude ./target_*/build directories from format check

* Run rustfmt only on project files

* add ulimit setup for long clang list

* merge

* fix rustfmt, exclude target Inc directory

* sync with master

* abspath
