Summary:
Two issues in the previous code:
1. We'd just tack on `#compilation-database` so if there already are `#flavors`
in a Buck target then we get a malformed `#flavors#compilation-database`
instead of `#flavors,compilation-database`. There's already code to deal
with that for other flavors (`#infer-capture-all`), so extend and reuse that.
2. The code didn't work if there are spaces in target names (sigh). Harden the
code a bit so that it works. Unfortunately Buck doesn't escape spaces at all
in its `buck targets --show-output` output, so the parsing still relies on
there being no spaces in flavors to work correctly. Sample output:
```
$ buck targets --show-full-output //clang_compilation_database:Hel\ lo#compilation-database
Not using buckd because watchman isn't installed.

Summary:
It is definitely useful to collect information about how long the analysis of every procedure takes. It allows to detect and focus on outliers when trying to improve performance. However, this kind of information could be collected using a standard logging mechanism and does not need to be stored within the analysis artifacts.
I intend to add some form of similar logging in the context of #16348004 once we can get every analysis procedure analyzed through the `Ondemand` module. In this case, it would be easy to have a single place to log how does the analysis of a procedure take.

Changes every checker to take a summary as parameter and return the updated summary to the next checker. Since several operations, like `Reporting.log_*` are modifying the summary in memory by loading them from the in-memory cache of summaries, we currently need to rely on `Specs.get_summary_unsafe` to return the updated version of the summary.
This diff allows to change the API of `Reporting` to take a summary as input and progressively remove all the calls `Specs.get_summary_unsafe` independently from adding the possibility to run several checkers at the same time.

Add a new command-line option `--per-procedure-parallelism`, to change the granularity of parallelism of the analysis from file to procedure.
This is intended for `--reactive` mode where e.g. a single file is changed and the analysis currently uses just one core.
When the option is used, the Makefile mechanism is replaced by using forking instead.
The parent process does as little allocation as possible, to avoid taxing the kernel.
Caveats:

- Not active in checkers, yet.

We're not actually tracking safe writes yet, but this domain will make it easy to do so.

Summary:
A good first step in order to run multiple checkers together is to prevent the analysis the analysis to side effect on the summaries of the method being analyzed from disk, or the shared specs summary. The idea is that `Ondemand` creates a summary for the procedure being analyzed and only saves the summary once all the checkers have been run. The summary for the caller (i.e. the procedure being analyzed) should never be looked up from disk during the analysis. In other words, the analysis should only ever lookup the summaries of the callees and the proposed solution to enforce this is to have `Ondemand.analyze_proc_name` be the only way to lookup the summary of a procedure.
Another objective is to make sure that the summaries are never saved to disk more than once.

Summary:
- inferbo introduced a dependency to extlib. When building Java analyzers, this
is implicitly pulled in by javalib, but it's missing when building only the
clang analyzers. Add `extlib` to the packages we build against.
- infer.ml and Javac.ml depend on Javalib, but it's easy to push down the code
that needs it to `jMain.ml` so that we can build without javalib for the
clang-only case.
- jMain.mli had 2 copies: one in java/ and one in java_stubs/. Make one a symlink to the other.
