Summary:
There's a lot of code for building up and moving around `Tags`.
When working on cleaning up some of the `Errlog` code, I noticed that `Tags` were included in the JSON and wondered why.
The answer is suprisingly just one thing: only the line tags get used, and even then they are only used to decide what frame to select as the start frame for the trace (i.e., the one that is highlighted first).
That seems like overkill; starting on trace on the actual line where the error occurs, starting at the beginning of the procedure where the error occurs, or starting at the first line of the trace all seem equally reasonable.
If we are happy with any of these alternatives, we can kill `Tags` altogether and potentially save a decent amount space in our JSON artifacts.

Deduping issues when generating a single report and then diffing the
reports can lead to introduced issues being considered duplicates of
existing issues.

Summary:
This diff takes the first step toward a more general filtering
system. This step is concerned only with filtering at the reporting
stage, filtering for the capture and analysis stages is left for
later.
This diff adds a new command line / config option
```
--filter-report +string
Specify a filter for issues to report. If multiple filters are
specified, they are applied in the order in which they are
specified. Each filter is applied to each issue detected, and only
issues which are accepted by all filters are reported. Each filter
is of the form:
`<issue_type_regex>:<filename_regex>:<reason_string>`. The first
two components are OCaml Str regular expressions, with an optional
`!` character prefix. If a regex has a `!` prefix, the polarity is
inverted, and the filter becomes a "blacklist" instead of a
"whitelist". Each filter is interpreted as an implication: an issue
matches if it does not match the `issue_type_regex` or if it does
match the `filename_regex`. The filenames that are tested by the
regex are relative to the `--project-root` directory. The
`<reason_string>` is a non-empty string used to explain why the
issue was filtered.

Summary:
Conversion and reformat of infer source using ocamlformat
auto-formatting tool.
Current status:
- Because Reason does not handle docstrings, the output of the
conversion is not 'Warning 50'-clean, meaning that there are
docstrings with ambiguous placement. I'll need to manually fix
them just before landing.

Summary:
Given two analysis results, it's now possible to compare them with the following command:
infer --diff --report-current reportA.json --report-previous reportB.json --file-renamings file_renamings.json
this command will then generate 3 files in `infer-out/differential/{introduced, fixed, preexisting}.json`, whose meaning is the following:
- `introduced.json` has all issues in `current` that are not in `previous`
- `fixed.json` has all issues in `previous` that are not in `current`
- `preexisting.json` has all issues that are in both `current` and `previous`
The json files generated can then be used to categorise results coming from incremental analyses of a codebase.
