Summary:
This diff enables parsing and auto-formatting documentation
comments (aka docstrings).
I have looked at this entire diff and manually made some changes to
improve the formatting. In some cases it looked like it would take too
much time, or benefit from someone more familiar with the code doing
it, and I instead disabled auto-formatting docstrings in those files.
Also, there are some source files where the docstrings are invalid,
and some where the structure detected by the parser appears not to
match what was intended. Auto-formatting has been disabled for these
files.

Summary:
Some field types of structs are missing in Java. The reason is:
* When capture, empty struct types are added without their fields.
* The empty struct types are overwritten to the global tenv when merging all tenvs.
As a fix, this diff add a boolean field, `dummy`, in `Typ.Struct.t`, then avoids that non-dummy types are replaced by dummy types.

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.

the camlp4 dependency. This is a minimal diff in order to update infer
opam depedencies.
Last (1.5.7) generates invokedynamic, but work on InvokeDynamic is still
in progress in Infer and not activated here yet. In this version, the
Java frontend will still replace any InvokeDynamic by a dummy
InvokeStatic call (as introduced by Jeremy a long time ago).

Summary:
It adds typ field in Sil.Store. The field will be used by the analyzer in the following diffs.
Motivation: Interbo generates a symbolic value when evaluating expressions including parameter symbols. At that time, it is done with depending on their types, e.g., an integer, a pointer to struct or a pointer to array. Without the type, it is hard to generate a correct symbolic value that will be instantiated later in call sites. Thus, evaluating RHS of the store statement, the type of RHS is better to be given.

- modify regexp used to parse `javac` output to work for all versions
- no need to be sure we are in Java 11 to match java 11-only method name in quandary
- for the rest, provide a command-line flag to specify the java version manually in case it differs from the version that infer was built against
- this only affects the Maven integration for now
To do all that, also change the configure script to record the version of java instead of just a boolean for whether it's >= 10.

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.
