Roland Reichwein 17799452d2
Add missing syntax checks (#1381) 
* Fix run-syntax-checks.sh to run with bash

Contains bash specific syntax, and sync with the other *.sh files
in this directory.

* Add missing header file adaptors to the directory and CMakeLists.txt

* run-syntax-checks.sh without ETL_IN_UNIT_TEST

* Fix usage of make_unsigned

* Removing crc.h from syntax checks because of redundancy

* Remove ETL_USING_CPP11 from unit tests

Unit tests are always run with at least C++11.

* Add missing copyright header in test_manchester.cpp

* Fixed usage of ETL_DEPRECATED_REASON(), wrong syntax by order
