Summary:
Also, make it explicit when we load the global tenv instead of the per-file tenv.
This allows for some nice simplifications in some places, notably:
- `tenv_file` is gone from `Exe_env.file_data`
- `DB.global_tenv_fname` is no more
This will help moving the tenv from the capture/source_file/ directories on the
filesystem to the database, as keys for the relevant table are `SourceFile.t`.

Summary:
They were constructed for each source file, and then joined into a global call
graph, only to get per-file lists of procedures. A tad wasteful.
Get this list from cfgs instead. Still record them in `exe_env` for now as
changing that code is a whole other beast.
One test falls victim of the flakiness of the analysis of recursive functions.

Summary:
Last piece of significant logic relying on the call graph: the execution
environment. Mostly carve out the logic to detect duplicate symbols to not rely
on the call graph.
Also make the keys of the `file_map` be source files, because not having the
"cg filename" makes it harder otherwise.

Summary:
In preparation for getting rid of call graphs, we need to find another way to
get the list of defined procedures (which is the only place where we use the
globally-computed call graph for now).
The natural way to get the list of procedures defined in a file is to load the
cfg for that file and look at the proc names that are the keys of the cfg. This
is way too expensive, as the CFG is big. Thus, we cache this list of proc names
as another column in the SQLite database of cfgs. This gives good performance
in benchmarks.

Summary:
Record the db schema, infer version, and run dates into
infer-out/.infer_runstate.json. This allows us to check on startup whether the
results directory was generated using a compatible version of infer or not, and
give a better error message in the latter case than some SQLite error about
mismatching tables.
This will be used in a follow-up diff to record capture phases too, and avoid
relying on filesystem timestamps of the infer-out/capture/foo/ directories for
reactive analysis.
Had to change some tests Makefiles to make sure they do not attempt to re-use
stale infer-out directories, which would now fail the run.
The stale infer-out directory gets deleted if `--force-delete-results-dir` is
passed (but a warning still gets printed).

Previously imports with relative filenames would not get resolved so the result

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.

Found the dead code with the script in the next commit, iteratively until no

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:
Some commands (mostly `infer report`) would attempt to run the initialisation
code of infer from the default results directory instead of the one used by the
test. This is mostly harmless because we do not actually use anything from the
directory (typically, we pass `--from-json-results foo.json` and only foo.json
matters). However, this can trip the initialisation code, eg on db schema
changes.
