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:
In some `make` versions, when not passing any single-letter options explicitly
from the command line it could be that the first word of `MAKEFLAGS` is some
`--long-option` instead, and this trips the detections of `-s`. If the first
word starts with `-` it will now be ignored.

Summary:
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.

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.

Changing directories can be surprising, don't do it as it doesn't seem to be

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.

Exposing the in-memory cache seems dangerous. There were only 2 uses anyway:
eradicate and biabduction. I think the biabduction one is safe to remove. The
eradicate one I do not really understand as we return a different summary than

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.

Summary:
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.

Print the following for each source file to analyse in non-interactive mode:

This should help diagnose when infer is stuck. It also logs this information to
the log file regardless of the form of the progress bar.
Also add a `--progress-bar-style` option to allow the user to force a
particular rendering: plain (as above), multiline (The Glorious One), or auto
(selection depends on whether infer is connected to a TTY on stdin *and*
stderr).
