Summary:
Callsites of `Reporting.log_error/warning` always use `Exceptions.Checkers`, let's simplify the API.
Under the hood it still creates an exception, but this can be cleaned up later.

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.

Summary:
Was trying to decide where to add a new Java utility function and realized that things are a bit disorganized.
Some operations on `Typ.Name.t`'s live in `Typ.Procname`, and some live inside an inner `Java` module whereas some are outside of the module with a `java_` prefix.
Let's move toward putting all Java/C/Objc/C++-specific functions in dedicated modules.
This diff does some of the work for Java.
There are Java-specific functions that operate on `Typ.Procname.t`'s that will have to be converted to work on `Typ.Procname.Java.t`'s, but changing those clients will be more involved.
Will also move C/Objc/C++ functions in a follow-up.

Summary:
Found the dead code with the script in the next commit, iteratively until no
warnings remained.
Methodology:
1. I kept pretty-printers for values, which can be useful to use from infer's REPL (or
when printf-debugging infer in general)
2. I kept functions that formed some consistent API (but not often, so YMMV), for instance if it looked like `Set.S`, or if it provides utility functions for stuff in development (mostly the procname dispatcher functions)
3. I tried not to lose comments associated with values no longer exported: if the value is commented in the .mli and not the .ml, I moved the comment
4. Some comments needed updating (not claiming I caught all of those)
5. Sometimes I rewrote the comments a bit when I noticed mis-attached comments

Summary:
Naming a variable `_foo` makes the compiler not warn about them if they are
unused, but there are lots of instances of such variables in the code where
they are in fact used, defeating the warning and introducing confusion for
those used to this naming convention.
Basically `sed -i -e "s/ _\([a-zA-Z][a-zA-Z0-9_']*\)/ \1_/g" **/*.ml` followed
by manual fixing of compilation errors (lots of `compare__foo` ->
`compare_foo_`).

Summary:
Instead of a whitelist and blacklist and default issue types and default
blacklist and filtering, consider a simpler semantics where
1. checkers can be individually turned on or off on the command line
2. most checkers are on by default
3. `--no-filtering` turns all issue types on, but they can then be turned off again by further arguments
This provides a more flexible CLI and is similar to other options in the infer
CLI, where "global" behaviour is generally avoided.
Dynamically created checkers (eg, AL linters) cause some complications in the
implementation but I think the semantics is still clear.
Also change the name of the option to mention "issue types" instead of
"checks", since the latter can be confused with "checkers".
