Modify travis-ci, fix issues

Added:
* Release/Debug job for gcc 7 and clang 3.5
* Debug asan gcc 7 job
* Debug tsan gcc 7 job
* Disabled extensions
* Added a spdlog::spdlog alias for tests

Removed:
* Valgrind workaround, the current version is 3.10.1
* install_libcxx
* Makefiles

Fixed:
* examples build
* multisink build

Workarounds:
* gcc7 with tsan and asan needs gold linker, otherwise build
  fails becase of unrecognized option '--push-state'
