Summary: No dummy node key, as a consequence the option `--skip-duplicated-types` will have no effect on issues with no node key, i.e. issues reported by non-biabduction non-eradicate checkers.

Summary: We report dead store false positives in template arguments when constexpr is used. To remove the false positives, with the expense of some false negatives, we do not report dead stores on constexpr anymore.

Summary:
Lambdas can capture references to locals of the enclosing method as long as
they are not propagated outside the method. However to keep things simple
always allow them to capture locals of the enclosing method at the price of
some false negatives.

Summary:
Before we would convert it to string in `Reporting` and pass it to `Errlog` which would use it only to 'log events'.
I guess the reason is that there was a cyclic dependency between `Errlog` and `clang_method_kind` defined in `ProcAttributes`.
This diff:
- moves it to its own module
- defers the conversion to string

Summary:
- abstracted the type for a node key
- moved it to its own module with an ugly `compute` to avoid cyclic dependencies...
- renamed `node_id` to `node_id_key` where needed
- moved key computation from `State` to `Procdesc.Node`

Summary:
- made arguments of `Errlog.log_issue` mandatory
- pushed some arguments of `log_issue_from_errlog` higher in the stack, the goal is to make sure `State` is only used in analyses that update it (biabduction and eradicate, if I'm correct)

Summary: C++17 introduce guaranteed copy elision which omits constructor calls. In ownership analysis, we depended on these constructor calls to acquire ownership. In particular, when a method returns struct, previously, a constructor was used to acquire ownership. In this diff, we acquire ownership of the returned structs directly.

Summary:
The internal concept of "kind" should in fact be named "severity" to match the convention used by many other tools, whereas the internal concept of "severity", i.e "HIGH", "MEDIUM" and "LOW" was never used and in any case redundant with the concept of "info", "warning", "error".
This diff maps both the "kind" and "severity" fields to value of the form "advice", "info", "warning", and "error" to be able to progressively migrate the code using the "kind" field.

Summary:
When `--reanalyze` is passed, mark the summaries of procedures matching
`--procedures-filter` as needing to be analysed before running the analysis.
This allows one to, for instance, re-run the analysis in debug mode on only
some files or procedures. However, this won't work for the Java Buck
integration since the summaries are hidden away in buck-out.

Summary:
Filtering on the SQLite side was done to be more efficient, but these are debug
options so it should be fine for them to be not very optimised.
Filtering on the OCaml side will allow us to re-use these filtering options for
other purposes, such as re-analysing certain procedures only.
