Cosmetic improvements in new config_info code.
Coverity griped about use of unchecked strcpy() into a local variable.There's unlikely to be any actual bug there, since no caller would bepassing a path longer than MAXPGPATH, but nonetheless use of strlcpy()seems preferable.While at it, get rid of unmaintainable separation between list offield names and list of field values in favor of initializing themin parallel. And we might as well declare get_configdata()'s pathargument as const char *, even though no current caller needs that.
