Addresses FI 9

The variables of library tag types need to be inline variables. Otherwise, using them in inline functions in multiple translation units is an ODR violation.

Proposed change: Make piecewise_construct, allocator_arg, nullopt, (the in_place_tags after they are made regular tags), defer_lock, try_to_lock and adopt_lock inline.
