Summary:
Currently, we report on all functions that are not config checked. However, the aim of the analysis is to only report on these for specific functions. Moreover, this has performance implications in practice.
This diff instead reports on functions that occur on a json file that is passed by the command line option `config-data-file`.

Summary:
ClangWrapper.ml was skipping clang commands that didn't capture
by default. It was using the 'skip_analysis_in_path_skips_compilation'
flag to NOT skip commands. This is a confusing use of that flag.
Default should be to run clang (in case it does something useful),
and a new flag to disable this.

Summary:
Races in Nullsafe classes can undermine NPE safety despite the class passing the type checks.
This diff adds to the report text of THREAD_SAFETY_VIOLATION and GUARDEDBY_VIOLATION the following trailer:
> Data races in `Nullsafe` classes may still cause NPEs.
This only happens if the race is directly on a non-primitively-typed member field of the class.
It also uses distinct bug types (adds the suffix _NULLSAFE to the bug types above) for easier accounting.

Summary:
`SettableFuture.set` invokes callbacks registered prior to the call, which may also try to acquire extra locks. If the called of `set` already holds a lock this creates lock dependencies which may lead to deadlocks.
Here we warn whenever `set` is called under a lock taken in a different source file. This avoids reporting when a class internally manages locks and calls `set`, reasoning that developers will be aware this is happening.

otherwise the menu pollutes the json.

Summary:
This diff adds a new experimental checker for detecting size of objects in autorelease pool in ObjC. The basic mechanism is almost the same with the previous cost calculation:
* Autorelease pool size is increased at explicit `autorelease` call
* Autorelease pool size is set as zero by the `autoreleasepool` block.
While it only supports the explicit calls as of now, we will extend the checker to handle more cases in the following diffs.

Summary:
This diff adds a prototype of a new checker that collects config checkings between markers.
Basically, what the checker is doing is a taint analysis.
* Taint source: function calls of "marker start"
* Taint sink: function calls of config checking
* Taint remove: function calls of "marker end"
By the taint analysis, the analysis results will say that which taints can reach to the sink. In other words, which marker ID that has been started can reach to the config checks, before marker's ending.
I am separating the diff into three steps:
(1/3) Add basic abstract semantics
(2/3) Add trace information
(3/3) Add reporting with test examples
