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.

Use `ignore` instead, as this will warn if the argument is an arrow type,
unlike `let _ = ...`. This makes the code more future-proof: if an argument is
added to a function called in `let _ = f x` then the compiler will complain
instead of silently turning a value into a partial evaluation.
Also got rid of particularly irksome `let _ = <stuff returning unit> in` where I could.

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:
Some paths are hardcoded in infer as being relative to the current executable,
for instance the directory where to find the models. By copying infertop.bc to
infer/bin like we do for `infer` these relative paths lead to the expected
place, which means models can be loaded in the toplevel like they would be in a
normal infer execution. This is more useful for debugging than previously.

Summary:
When we see `pthread_create(..., ..., foo, ...)`, we want to call the function
`foo` to check that its precondition is met. The initial goal was to get rid
of the uncouth call to `Summary.get` when what we really want is to analyse
`foo` instead of just betting on the fact that it has been analysed already.
Besides switching to `Ondemand.analyze_proc_name`, this also changes the
matching of the function pointer in the arguments of `pthread_create()` to
detect the common case of a constant function name. I also added tests.

Because of the custom formatting we do on top of `Cmdliner.Manpage` in
`CommandLineOption`, the long `$(b,strings inside bold block)` would sometimes
end up split across several lines and then `Cmdliner` complains about the line
ending before having seen the closing parenthesis `)`.
Instead of allowing these long strings, remove then from the help message as
they don't seem very useful to me. Replace them with just a mention of
`--test-determinator` so all the options related to Test Determinator are easy
to look up.
Also change the relevant options from `CLOpt.mk_string` to `CLOpt.mk_path`
because they look like they are supposed to be paths.

- Each Mem domain value includes one relational value containing relations among symbols. The relational values are modified by the `Prune` and `Store` commands.

Summary:
Litho uses an idiom as follows. `Component.Builder` has an abstract method `T getThis()` which is supposed to be implemented as `{return this;}`.
I believe the reason it's there is to have covariant return types in subclasses, though this doesn't really matter.
We don't do dynamic dispatch, so instead of summarising `getThis` as having a return ownership of `OwnedIf({ 0 })` we just return `Unowned`.
This is generating many false positives, which are really hard to debug.
Here I'm special-casing any abstract method whose return type is equal to that of it's only argument, to return conditional ownership.
