Rewrite uses of boost::optional

...to only use functions that are also available for std::optional (in
preparation for changing from boost::optional to std::optional):

* uses of get are replaced with operator * or operator ->
* uses of is_initialized are replaced with operator bool
* uses of reset with an argument are replace with operator =

(All of the replacements are also available for boost::optional "since forever",
so this change should not break builds against old --with-system-boost.  An
alternative replacement for is_initialized would have been has_value, but that
is only available since Boost 1.68.)
