Summary:
`Errlog` will merge similar issues (same severity, name, description) reported at the same location, so let's make sure the locaiton is mandatory.
Issues:
- errors happening in `Ondemand` still use the `State` which makes sense only for biabduction and eradicate
- a case of `NullabilitySuggest` didn't have a location, I did my best to patch it but I'm sure the location could be more precise

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:
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.

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
the one we cache... the tests pass though.

Summary:
Print the following for each source file to analyse in non-interactive mode:
```
path/to/source_file.c starting
[...]
path/to/source_file.c DONE in <time>
```
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).

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.

Filtering on the SQLite side was done to be more efficient, but these are debug

Filtering on the OCaml side will allow us to re-use these filtering options for

Summary:
This changes the behaviour back to before the "fork once then pipe new tasks
for each source files" era: before that we would fork once per source file,
which had the effect of emptying the caches for every source file. Without this
the caches can grow unchecked.
This is probably suboptimal but should at least be the same behaviour as before.

This works by setting up a worker pool (as before) that waits to receive jobs
(not as before: we used to fork for each new job). Unix pipes are used for
communication.
The new worker pool can be used to experiment with other concurrency models,
such as reviving per-procedure-parallelism, or making sure each procedure is
analysed only once.
Perf tests indicate that this version is no slower than the previous one,
either on laptops or devserver: about 3% worse user time but ~40% better system time.
This new version forks <jobs> processes whereas the previous version would
fork `O(number of source files)` times.
`infer -j 1` shows a progress bar that doesn't update timing info (because it
would need a second process to do that).

Summary:
The execution environment is really just a cache. It happens to point to a
particular source file which is where the analysis was started from, but that
is not relevant, and in fact is confusing because it suggests that it is
somewhat tied to that file. In reality, exe_env caches information about any
procedure and source file encountered by the analysis.
This will make it easier to make further changes but I think it also brings a
bit more clarity to the code.
