C++: Implement Pos and Spec as int, not newtype
...
This change gives a slight performance improvement and makes the QL code
shorter. It introduces some magic numbers in the code, but those are
confined to the `Pos` and `Spec` classes.
We get a speed-up because the evaluator has built-in support for integer
literals in the `OUTPUT` of `JOIN` operations, whereas `newtype`s have
to be explicitly joined on. As a result, a predicate like
`CFG::straightLineSparse#ffff` drops from 262 pipeline nodes to 242.
I measured performance on https://github.com/jluttine/suitesparse , which
is one of the projects that had the biggest slowdown when enabling the
QL CFG on lgtm.com. I took two measurements before this change and two
after. The `CFG.qll` stage took 117s and 112s before, and it took 106s
and 107s after.

Add qlpack.json files
...
Eventually these files will subsume the current `queries.xml` files
at the top of query-containing and library directories. For now they're
just here to support internal testing of the tooling support for them
we're writing on.
Format and contents is a work in progress. If you're not in Semmle,
don't depend on anything here making sense (or staying stable) until
you see the version tags increase to something nonzero.
