Summary:
`make doc` will use `jbuilder` (which in turn uses `odoc`) to generate the
documentation for infer's modules. This is useful to browse the APIs of infer
and gives a more discoverable place to host more general documentation about
infer's internals.
Besides the actual plumbing necessary to generate the docs, this diff also
- Moves the various infer/src/*/README.md to index.mld files that make it to the generated docs
- Fixes some doc comments that would anger `ocamldoc`
Closes#435

Summary:
- Rather than passing a directory name to PerfStats reporting api to write the stats to, and then determining the EventLogger `stats_type` from that dirname, there is now a `stats_type` type in PerfStats, and the directory name and EventLogger tag is automatically determined from that type after it is passed to the API
- This allows us to determine whether we're in capture mode or linters mode dynamically from PerfStats itself, and use the appropriate tag when creating an event

Summary:
Instead of storing the type environment in infer-out/captured/foo.c/foo.c.tenv,
store it in the `source_files` table of the SQLite db. This limits the number
of files we create on disk.
The "file local" type environemnts are specific to the clang integration. For
Java, there is a "global tenv" file. Instead of matching on string names, this
diff also makes the API of `Tenv` reflect this situation.
The global tenv is serialized as a separate file in "infer-out/.global.tenv"
instead of "infer-out/captured/global.tenv", because "infer-out/captured/" will
soon be removed as it now only contains the global tenv (except in debug mode,
where it will still be created).
In the DB, we either store the local tenv for the file, or "global" to indicate
that the global tenv should be consulted.
This diff also moves `Cfg.store` to `SourceFiles.add` because that function
deals with more than just `Cfg.t`.

Summary:
This allows Eradicate to lookup the annotations from the classpath and without requiring the code in the classpath to have been previously analyzed. The benefit is that source files can be analyzed independently of each other as long as the classpath is known.
The main goal is to run be able to run Eradicate as a linter without losing warnings.
We may have to add some more models of the standard libraries as no `Nullable` on a parameter does not necessarily mean that the method does not accept `null`.

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`.

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.
