-Disable LINTing in test macros with comment // NOLINT
-Enable static analyzers for c++ tests
-Switch app4triqs_c to static library
Dynamic was pickung up previously installed libapp4triqs_c.so in tests
Also there is no need to be dynamic for applications
-Fix previous change in HeaderFilterRegex:
'app4triqs/c++' was blocking all headers for clang-tidy checks.
'app4triqs' works well, but we cannot install any other headers into
app4triqs folder structure.
We thus had to create INSTALL_DIR in travis.yml
-consistent indends in all cmake files
-add static analyzer checks with both cppcheck and clang-tidy
-add dynamic analyzer checks with Address Sanitizer and option ASAN
-add dynamic analyzer checks with Undefined Behavior Sanitizer and option UBSAN
-Further Cleaning and Comments
