Summary:
This allows Eradicate to lookup the annotations from the classpath and without requiring the code in the classpath to have been previously analyzed. The benefit is that source files can be analyzed independently of each other as long as the classpath is known.
The main goal is to run be able to run Eradicate as a linter without losing warnings.
We may have to add some more models of the standard libraries as no `Nullable` on a parameter does not necessarily mean that the method does not accept `null`.

We already knew not to warn when non-resource `Closeable`'s like `ByteArrayOutputStream` weren't closed, but we still warned on their subtypes.
This diff fixes that problem by checking subclasses in the frontend.
This also removes the need for Java source code models of non-resource types, so I removed them.

They were constructed for each source file, and then joined into a global call

Get this list from cfgs instead. Still record them in `exe_env` for now as

One test falls victim of the flakiness of the analysis of recursive functions.

Summary:
Was trying to decide where to add a new Java utility function and realized that things are a bit disorganized.
Some operations on `Typ.Name.t`'s live in `Typ.Procname`, and some live inside an inner `Java` module whereas some are outside of the module with a `java_` prefix.
Let's move toward putting all Java/C/Objc/C++-specific functions in dedicated modules.
This diff does some of the work for Java.
There are Java-specific functions that operate on `Typ.Procname.t`'s that will have to be converted to work on `Typ.Procname.Java.t`'s, but changing those clients will be more involved.
Will also move C/Objc/C++ functions in a follow-up.

Summary:
This approach was requiring the `InferArray` class to always be part of the classpath, and the only benefit was to preserve the length of the arrays, when known, on calls to `clone()` method. However, adding it to the models would create circular dependencies between the models, the builtins and the tests.
The code is now simpler and we can more aggressively fail when classes that are supposed to be found from the classpath are not found.

Summary:
Change the API of `Logging` wrt to writing to files and to the console (see
changes in logging.mli).
Write only to one log file: infer-out/log. Prefix each line with the kind of
warning and the PID of the process emitting it. Writing with `O_APPEND` is
atomic so the file should not get garbled by concurrent writes. To get the
output of a single process, find out which one interests you by looking at
infer-out/log, then `grep ^[<PID>] infer-out/log`.
Introduce 3 log levels for debug output and command-line options to set them
for various categories individually.
Change tons of `"\n"` to `"@\n"` so the `Format` module is aware of newlines
without us having to look through every character of every logged string for
`\n` characters.

Summary:
Try and enforce the following rules:
- stderr is for updating the user about progress or errors
- Introduce Logging.progress that outputs to stderr, but honours --quiet
- Logging.stderr is as before
- Logging.out now prints to stderr (or to log files as before if set up) and
not stdout. If some information should go on stdout then the user should be
able to rely on it (ie, it's not just some progress message). For now only
the summary of the errors is printed on stdout by default.
- Logging.err* functions are gone. If the error is user-visible, it should be
Logging.stderr, or `failwith`. If not, go to the same log file as other
output, which personally I find much more convenient than having to dig through
2 log files every time I'm looking for some output.

Summary:
Limit the use of `SourceFile.invalid` (renamed from `SourceFile.empty`) as much
as possible. In particular, do not generate bogus procnames for external global
variables: their translation unit was set to the invalid source file, now we
distinguish between extern/non-extern global variables more explicitly.
`SourceFile.invalid` is still used in too many places to actually remove it, often as a dummy initial value that never gets used, but sometimes as an actual value... Worse, we cannot fail on all operations on `SourceFile.Invalid` yet: the `SourceFile.to_string` method is used in too many places where it could get `SourceFile.Invalid` as argument. It's easy to see where it's used by making it raise in the code, then running the tests. This results in spaghetti backtraces that are hard to trace back to a root cause.
