documented non-const reference passing to erase_if (#312)

* documented non-const reference passing to erase_if

* prevented warning as error in Boost.Container build

* skipped tests for MinGW (https://github.com/boostorg/atomic/pull/70)

* correct reference link for previous commit is https://github.com/boostorg/atomic/issues/73

* commented previous disabled cases

* disabled cfoa_serialization_tests with TSAN

* fixed previous
