Summary:
Once the fixed/preexisting/introduced sets have been computed, they endure
further filtering which may decide that more of them are equal. These bugs just
get dropped on the floor. Put these into preexisting as well instead, at least
in the case of the "skip_duplicated_types_on_filenames" filter.

:
What is relevant for the Buck integration is not the list of bugs that we find in a single target, which is essentially identical to testing `infer -- javac ...`, but to make sure that we still find the issues that are involving several Buck targets, and later other things like the caching mechanism.
This should also make the tests faster.

Summary:
This messes up with the Buck cache: if infer recaptures a file with only trivial changes that shouldn't affect the capture Buck will still believe it has to reanalyze everything that depends on that file if there's non-deterministic data in infer's output.
Re-use the `--buck` flag used by the Java Buck integration for mostly the same purposes. Add a few special cases for the flavours integration (eg: keep capture data).
Change perf stats registration to take `Config.buck_cache_mode` into account instead of relying on each call site to handle that peculiarity correctly. Also, there's no need to create the perf stats directories before calling the registration function since it will do that too.

Summary:
Introduce `infer-<command>` for each command, except for internal commands
(only `infer-clang` for now) which are not exported. Install these executables
(which are just symlinks to `infer`) on `make install`. The main executable
looks at the name it was invoked with to figure out if it should behave as a
particular command.
Get rid of `InferClang`, `InferAnalyze`, and `InferPrint`. As a bonus, we now
only need to build one executable: `infer`, which should be a few seconds
faster (less link time).
`InferAnalyze` is now `infer-analyze` and `InferPrint` is `infer-print`. To run
`InferClang`, use a symlink named `clang`, `clang++`, etc. to `infer`. There
are such symlinks available in "infer/lib/wrappers/" already.
I also noticed that the scripts in xcodebuild_wrappers/ don't seem useful
anymore, so use wrappers/ instead, as for `make`.

Summary:
Try to read .inferconfig in the current directory, then in .., then in ../..,
etc. This can be overriden with the `INFERCONFIG` environment variable.
This removes the need for two-phase parsing, so clean up that code too.
Paths in .inferconfig are interpreted relative to where .inferconfig is located.
This does not apply to other path-sensitive things like regexpes... this is not
a show stopper because regexpes can account for the fact that infer may be
called from different project roots.
Make sure we fail when .inferconfig exists but cannot be read.

Summary:
Most of our tests work by comparing the output of some command to a baseline
expected output. It's often needed to update that baseline.
Previously, that was crudely done by attempting to move every foo.exp.test file
to foo.exp. This does not work terribly well, in particular because
foo.exp.test might be stale.
Instead, add a `replace` target to every test that knows how to update the
baseline. This allows custom behaviours too, eg in the differential tests.
Most of the tests include base.make or differential.make, so add a replace target
there. A few tests are completely custom, add a replace target to them too.

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.

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:
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
