Summary:
Run all clang tests with project-root at `infer/tests`. I need it because we'll start resolving symbolic links
soon and some tests would lead outside of project root which means we'd start seeing absolute paths in recorded tests.

Summary:
Let's introduce some concepts. A "known unknown" function is one for which no Java code exists (e.g., `native`, `abstract`, and `interface methods`). An "unknown unknown" function is one for which Java code may or may not exist, but we don't have the code or we choose not to analyze it (e.g., non-modeled methods from the core Java or Android libraries).
Previously, Quandary handled both known unknowns and unknown unknowns by propagating taint from the parameters of the unknown function to its return value. It turns out that it is really expensive to do this for known unknown functions. D4142697 was the diff that starting handling known unknown functions in this way, and bisecting shows that it was the start of the recent performance problems for Quandary.
This diff essentially reverts D4142697 by handling known unknowns as skips instead. Pragmatically, doing the propagation trick for Java/Android library functions (e.g., `String` functions!) matters much more, so i'm not too worried about the missed behaviors from this. Ideally, we will go back to the old handling once performance has improved (have lots of ideas there). But I need this to unblock me in the meantime.

Summary:
introduce `AttributesTable.load_defined_attributes` which will return proc attributes only if the procedure is defined. In order to not mess up
with existing caching, create another hashmap to store those procdescs.
We need to do that because with reactive capture we no longer can assume that all proc attributes are final before analysis starts

Summary: The default `android.jar` used to compile Android code is just a list of empty method stubs that is used for the type checking. In order to improve the type information, we used to redirect the bootclasspath to another `android.jar` that was containing the method bodies and all the fields including the private ones. Since we no longer need the types in the models and the types in the libraries to match, this is now dead code.

Summary: Currently the thread safety checker neglects to analyze and files methods we don't want to report on. Like constructors and private methods, and classes where no superclass is marked ThreadSafe. For interprocedural analysis we want to analyze all these to get summaries, even if we don't report on them.

Summary:
`abs_source_file_from_path` is dangerous because
1. It's not trying to make path relative to `project_root` - you can't compare two files created with two different methods
2. It's making relative paths relative to `getcwd` instead of `project_root` which is different from `from_string` function.
Also remove unused `DB.inode_equal`

Summary:
1. Always store cpp model source_file with relative path. This will make them cache friendly independent of infer location
2. Distinguish between "relative to project root" and "relative to infer models src"
3. Unify `source_file_from_path` used by java and C frontends into one function. There are no improvements to that logic yet
4. Move `is_cpp_model_file` to use `source_file` instead of `filename`
