Log message:
        This is a major update, which switches virtually every 
allocated-but-not-freed
        string into the strcache.  As a side-effect, many more structure 
members and
        function arguments can/should be declared const.
        
        As mentioned in the changelog, unfortunately measurement shows that this
        change does not yet reduce memory.  The problem is with secondary 
expansion:
        because of this we store all the prerequisites in the string cache 
twice.
        First we store the prerequisite string after initial expansion but 
before
        secondary expansion, then we store each individual file after secondary
        expansion and expand_deps().  I plan to change expand_deps() to be 
callable
        in either context (eval or snap_deps) then have non-second-expansion
        targets call expand_deps() during eval, so that we only need to store 
that
        dependency list once.
