Summary:
In `Config`, the lists generated by `mk_string_list`, `mk_path_list`, `mk_rest_actions` are reversed implicitly, which made it hard for developers to use them correctly. What the previous and this diff will do is to change the list variables of the `Config` to not-reversed one.
* diff1: First diff adds `RevList` to distinguish reversed lists explicitly. All usages of the reversed list should be changed to use `RevList`'s lib calls.
* diff2: Then this diff will change types of `Config` variables to not-reversed, normal list.

Summary:
Warning: This might be a bit brutal.
PerfStats and EventLogger are pretty much subsumed by `ScubaLogging`.
It seems no one has been looking at the data they generate recently.
Let's delete them! If we need to re-implement some parts later on, let's
do that using `ScubaLogging`, which is better (eg, still produces data
when infer crashes).
Things we lose:
- errors in the clang frontend due to missing decl translation, etc.
- errors in biabduction due to timeouts, functions not found, etc.
We could also re-implement these using BackendStats and ScubaLogging
instead of brutally deleting everything.

Summary:
From a set of classes [classes], JClasspath.load_program builds a
program. This program contains (implicitely) the set of active classes
and we should not keep using the set [classes] and the generated
program as the same time, because they may not be synched
anymore. (In particular, in a forthcoming diff load_program may add
new classes during program construction)
This patch forces this discipline. It adds a [in_classes]
query for programs and makes sure we use it everywhere we should.

Summary:
This also prints the CFGs *after* pre-analysis for individual procedures
in infer-out/captured/<filename>/<proc>.dot. One can also look up the
CFGs before pre-analysis in infer-out/captured/proc_cfgs_frontend.dot.
Context: I want to add a pre-analysis that needs to look at proc
attributes inter-procedurally. For this to make sense it has to happen
*after* all of capture, and before analysis.
Thus, this diff brings back the lazy running of the pre-analysis like in
D15803492, except that we still make sure to run the pre-analyses
systematically regardless of the checkers being run by running the
pre-analysis from ondemand.ml. Also we don't need to re-introduce the
"did_preanalysis" proc attribute for the same reason that the
pre-analysis is now run once and for all by ondemand.ml (instead of each
individual checker back in the days).
This has the benefit of running the pre-analysis only when needed, and
the drawback that several concurrent processes analysing the same proc
descs will duplicate work. Since pre-analyses are supposed to be very
fast I assume that neither is a big deal. If they become more expensive
then the benefit gets bigger and the drawback is just the same as with
regular analyses.

Summary:
I realized that there was a discrepancy in the # of instructions between whether we run a single analysis or multiple analyses at the same time. It turns out that in biabduction, bufferoverrun and other HIL analyses we did Preanalysis step (which adds scope instructions and invokes liveness etc.) but not in others. This discrepancy results in inconsistent analysis results (e.g. in the new inefficient-keyset-iterator) that rely on instructions. We should be consistent. Hence, we now invoke Preanalysis in the frontend and remove all other uses in the rest of the checkers.
Consequently, I had to update the inefficient-keyset-checker to take the CFG resulting from Preanalysis with extra scoping instructions.

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`.

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`.
