Instead, we now have a looser helper called `checkContains(...)` that will match on any occurrence similarly to `std.mem.indexOf()`. While at it, I have cleaned up other combinators to make the entire API more consistent, and so: * `checkStart(phrase)` is now `checkStart()` followed by `checkExact(phrase)` * `checkNext(phrase)` if matching exactly is now `checkExact(phrase)` * `checkNext(phrase)` if matching loosely is now `checkContains(phrase)` * `checkNext(phrase)` if matching exactly with var extractors is now `checkExtract(phrase)` Finally, `ElfDumper` is now dumping contents of `.symtab` and `.dynsym` symbol tables. I have also removed dumping of symtabs as optional - they are now always dumped which cleaned up the implementation even more.
