Summary:
All tests were redirecting `stderr` into duplicates.txt which made it much harder to see other error messages in stderr (such as uncaught exceptions).
To mitigate it, write duplicates to separate file and don't redirect `stderr` to another file.

Summary:
This option is not needed anymore as it was introduced to counter an uncovered
perf issue with creating human readable reports. The perf issue has been
addressed.
Instead of this option, one can use `infer --report-hook /bin/true ...` to
disable reporting. However, right now the Buck integration doesn't honor it so
this would need to be fixed to be a true equivalent of `--disable-bug-list`.

Summary:
Given two analysis results, it's now possible to compare them with the following command:
infer --diff --report-current reportA.json --report-previous reportB.json --file-renamings file_renamings.json
this command will then generate 3 files in `infer-out/differential/{introduced, fixed, preexisting}.json`, whose meaning is the following:
- `introduced.json` has all issues in `current` that are not in `previous`
- `fixed.json` has all issues in `previous` that are not in `current`
- `preexisting.json` has all issues that are in both `current` and `previous`
The json files generated can then be used to categorise results coming from incremental analyses of a codebase.

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.

Summary:
Sevel auxiliary files made it to the output directory of the analysis of individual targets when analyzing Java projects build with Buck. However, these files are then taken into account= to compute the target rule key and then to decide whether to analyze the dependent targets. Since these auxiliary files were containing time sentive information, every cach miss on a given target would then invalitate the cache entries for all the dependent targets.
This diff cleans up the output directory to only keep the specs files, the `global.tenv` and the `report.json` files which are the only artifacts needed to analyze the dependent targets
This diff makes a minimal number of changes to see how it behaves in prod, but I intend to refoctor this more when continuing to add support for running Infer with genrules

Xcode's compilation databases follows a different convention than cmake's and
escape the `"file"` and `"dir"` fields of each unit to make them shell-ready.
We need to treat them differently when reading them.
This adds a new `--clang-compilation-db-files-escaped` option and makes the
code related to reading compilation databases deal correctly with both

Clients should use `Config.parse_action` instead to figure in what mode they

In particular, the biggest change is in logging. Take the `parse_action` into
account instead of the exe, and change the log/ subdirectories to be "capture",
"driver", "analyze", and "print", corresponding to the various phases of an

Summary:
This replaces the previous integration written in Python, which consisted in 1)
run the mvn command and parse its output to locate "directories containing
source files", 2) run on files named "*.java" in these directories. This meant
we had to run javac twice on each source file, and more importantly this
mechanism of finding source files was very fragile. In fact, I could not make
it work on several mvn projects I tried.
The new integration is based on parsing "pom.xml" to add an "infer-capture"
profile which instructs mvn to run `/path/to/infer` instead of `javac`. We also
add this profile to each maven submodule.
Users can specify an "infer-capture" profile themselves if the default one
doesn't work; in that case we don't inject our own "infer-capture" profile.

Summary:
Previously, we would first compute which build command is at hand, based on the
first argument after "infer --", then do everything depending on that piece of
information. However, the build command alone is not enough to know in which
"build mode" we are operating. For instance, there are several build modes
corresponding to "buck" build commands.
This led to duplication of the logic (to retrieve which build mode we are in in
the various phases of an infer run), and some invariants that had to be
re-asserted at various points in the code, eg that the arguments are not empty.
This diff adds a `build_mode` type (renaming the previous `build_mode` to
`build_system`) that identifies the various integrations we support. We compute
the build mode at the start of infer, then pass the build mode around.
Also, move `run_javac` to a new `integration/Javac.ml` file given that it's a
bit large.

Summary:
Currently, if we don't find `-d` or `-classes_out` on the command line then we
tell javac to redirect the compiled classes in some other directory, by default
the initial working directory. But we don't detect when these arguments are
hidden inside files (`foo` arguments on the javac command line) so the
heuristic was incomplete. Look inside these files to better tell whether we need
to make up an output directory or not.

Summary:
Turns out that swapping stdout and stderr using a temporary fd 3 was screwing
up with make's jobserver, who also uses fd 3!
Also, infer is partly to blame as it also calls `make`. Unsetting `MAKEFLAGS`
in infer tells `make` that the way infer calls `make` is independent from
parent `make` invocations.
Also, simplify the rules for direct tests and build system tests.
