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: 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:
Just a bunch of minor changes.
- The mutable field doesn't need to be mutable: it's only mutated once in the code somewhere that doesn't even need to mutate
- Hence the type can be public
- All the `ms_get_*` functions are replaced by field accesses
- `CMethod_signature` -> `CMethodSignature` while I'm at it, although maybe that's bad since other files in clang/ follow the former convention
- `type method_signature` -> `type t`
- `pp` function instead of `to_string`, since it's used with `fprintf`. This gets rid of the only caller of `IList.to_string`.

Summary:
The clang frontend uses `assert false` for unimplemented features that should
abort method translations, as well as for genuine internal errors.
Distinguishing between the two, we can fail hard on the latter and not the
former.
1. This introduces a new exception `Unimplemented` that is used instead of `assert false` where appropriate.
2. Changed some other cases into `die ...` (when there's an error message to display)
3. Wherever a path in the code that we assumed to be unreachable was observed reachable, we now raise `IncorrectAssumption`. These should be fixed, but the fixes are not obvious.

Summary:
Change the API of `Logging` wrt to writing to files and to the console (see
changes in logging.mli).
Write only to one log file: infer-out/log. Prefix each line with the kind of
warning and the PID of the process emitting it. Writing with `O_APPEND` is
atomic so the file should not get garbled by concurrent writes. To get the
output of a single process, find out which one interests you by looking at
infer-out/log, then `grep ^[<PID>] infer-out/log`.
Introduce 3 log levels for debug output and command-line options to set them
for various categories individually.
Change tons of `"\n"` to `"@\n"` so the `Format` module is aware of newlines
without us having to look through every character of every logged string for
`\n` characters.
