    Upgrade parsers to Bison >= 3.0 · b9808144
    Alexandre Duret-Lutz authored
    Bison 3.0 was released in 2013, and the current Debian stable (buster)
    has version 3.3.2.
    
    * m4/bison.m4: Remove -Wno-precedence and -Wno-empty-rule, keep
    -Wno-deprecated just to protect from future deprecation warnings that
    would be interpreted as errors.
    * spot/parseaut/parseaut.yy, spot/parsetl/parsetl.yy: Use %empty
    rules, prefer %precedence over %nonassoc, update %error-versbose and
    %name-prefix to their more modern equivalent.
    * spot/misc/trival.hh (maybe): Mark this function as noexcept to
    please the compiler while compiling the parsers.
