Summary:
This is a minimal change to (poorly) recognize and model std::mutex
lock and unlock methods, and to surface all thread safety issues for
C++ based on the computed summaries with no filtering.
This ignores much of the Java analysis, including everything about the
Threads domain. The S/N is comically low at this point.

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`.

rebuild it.

Try to read .inferconfig in the current directory, then in .., then in ../..,

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.

We shouldn't encourage contributors to run only a subset of the tests with

so.
Now `make test` will ensure that both the clang and the Java analyzers are
enabled, otherwise it will refuse to run and suggest to run `make config_tests`
instead.
It can still be useful to be able to run only the Java or Clang tests. The diff

Summary:
Nuking the specs then building the models was not a great idea: the models do
not look at specs but only at some dummy marker files, eg
infer/lib/specs/c_models, so they don't necessarily realize that they need to
be rebuilt when the specs have been nuked!
One easy workaround would be to also delete the marker files, but then we would
*always* rebuild the models when building infer. Not good.
The solution here is to nuke the specs and marker files only when the clang
dependencies change, then rebuild all the models.

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.

- `introduced.json` has all issues in `current` that are not in `previous`
- `fixed.json` has all issues in `previous` that are not in `current`

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.
