Summary:
If we couldn't project the callee access path into the caller during summary application, we still added the corresponding trace to the caller state.
This was wasteful; it just bloats the caller with state it will never look at.
Fixed it by making `get_caller_ap_node` return `None` when the state won't be visible in the caller.

It's distracting to see the debug HTML for the preanalysis when you're trying to debug something else.
Also, it breaks the nice bi-abduction debug feature of marking the visited nodes as green.

Summary:
We shouldn't encourage contributors to run only a subset of the tests with
`make test`, but it's more helpful to complain clearly should they try to do
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
also fixes the cases where that previously failed.

Summary:
This debugger stops the execution of CTL during the evaluation of formulas, then shows useful info about the current state:
- Which formula is being evaluated
- In which part of the AST is such formula being evaluated
- Line number of the source file
- Whether a CTL-Transition will take place or not
- Node-ID that can be related to the dotty file containing the evaluation graph (the one in infer-out/lint_dotty/)
The AST is shown with coloured nodes, where each colour has the following meaning:
- [Default terminal colour], Bold: The node is being evaluated
- Green, Bold: The formula returned true on the current node
- Red, Bold: The formula returned false on the current node

Summary:
Make it possible to write one model which will be used by all template instantiations.
There is one big missing piece: infer never tries to do template instantiation by itself. With current code, it's possible to use generic models
as long as header contains `__infer_generic_model` annotation (see the test as an example).
This is not viable to modify all headers with this annotation hence infer will try to do template instantiation for generic models in later diffs.

Summary:
Initial version of naming, required for generic models. It's simply non mangled name stripped from any template arguments.
This makes it impossible to have two generic models with
1. different template arguments
2. different overloads (function with same name, but different types of arguments)

- Print javac output when it fails.
- Refactor Javac.ml so that rerunning the command doesn't duplicate code.
The output of the clang and Javac integration is good, the output for mvn is
ok, the output for Buck is still fairly "meh".
