Summary:
1. `noexcept` was missing from `unique_ptr` constructors leading to compilation errors in some edge cases
2. In case `unique_ptr` specified custom deleter with custom `deleter::pointer`, there could be compilation errors due to invalid cast from `deleter::pointer` to `void*`. Add extra overload of `model_set` to prevent this issue

Summary:
This is a minimal change to (poorly) recognize and model std::mutex
lock and unlock methods, and to surface all thread safety issues for
C++ based on the computed summaries with no filtering.
This ignores much of the Java analysis, including everything about the
Threads domain. The S/N is comically low at this point.

This diff fixes unintentional bottoms in pointer arithmetic of inferbo.
The pointer arithmetic on addresses of variables (not array) just returns

Summary:
All files that match the regular-expressions passed via `--skip-analysis-in-path` are just compiled.
With this change, you can also opt for not compiling those files at all, by passing the `--skip-analysis-in-path-skips-compilation` argument

Summary:
A recent diff tried to replace `L.out "error message"; assert false` with
`failwith "error message"` but infer relies on the type of raised exceptions to
sometimes keep going. A more careful change will be needed but in the meantime
restore the old behaviour.

Summary:
Recently we changed the binaries we build and use but it wasn't obvious that
some of the old binaries disappeared. For instance, nothing short of `git clean
-xfd` would get rid of "infer/bin/InferPrint", which can lead to frustrating
attempts to make InferPrint not segfault.
Mitigate this in two ways:
- be more strict in the binaries we ignore in .gitignore, so InferPrint would should up in "git status"
- be less strict in the binaries we clean out with `make clean` so that
InferPrint et al. gets deleted by `make clean`

Summary:
Try and enforce the following rules:
- stderr is for updating the user about progress or errors
- Introduce Logging.progress that outputs to stderr, but honours --quiet
- Logging.stderr is as before
- Logging.out now prints to stderr (or to log files as before if set up) and
not stdout. If some information should go on stdout then the user should be
able to rely on it (ie, it's not just some progress message). For now only
the summary of the errors is printed on stdout by default.
- Logging.err* functions are gone. If the error is user-visible, it should be
Logging.stderr, or `failwith`. If not, go to the same log file as other
output, which personally I find much more convenient than having to dig through
2 log files every time I'm looking for some output.
