Summary: In Obj-C blocks, we explicitly insert reads of the captured vars. This does the same thing for C++. For example, `foo() { int x = 1; [x]() { return x; } }` would previously not contain a read of `x` in `foo`. Now, we'll create a temporary that reads from `x` and pass it to the closure value.

1) Fixes some false negatives when a method annotated with `nullable` in the header is not annotated in the implementation and the attribute lookup returns the implementation. In that case, we should follow the information given in the header.
2) Fixes some false positives when annotations are in the other way around, i.e. annotated in the implementation but not in the headers. For now, there should be no report in this case, but the analysis should be extended to report the inconsistency between the header and the implementation
3) Fixes some cases of weird reports caused by name conflicts where the method in the include has the same name has another method annotated differently.

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`.

Summary:
There's a lot of code for building up and moving around `Tags`.
When working on cleaning up some of the `Errlog` code, I noticed that `Tags` were included in the JSON and wondered why.
The answer is suprisingly just one thing: only the line tags get used, and even then they are only used to decide what frame to select as the start frame for the trace (i.e., the one that is highlighted first).
That seems like overkill; starting on trace on the actual line where the error occurs, starting at the beginning of the procedure where the error occurs, or starting at the first line of the trace all seem equally reasonable.
If we are happy with any of these alternatives, we can kill `Tags` altogether and potentially save a decent amount space in our JSON artifacts.

Summary:
In some cases infer runs clang commands where we do not attach the plugin,
notably for pre-processor-only commands like `clang -E foo.c`. Usually these
commands are used by build systems to test their output, so infer should not
swallow it.
This makes infer echo the stdout of clang whenever we do not attach the plugin
to clang. When the plugin is attached, stdout is captured because that's where
the plugin outputs its results, so we cannot do the same in this case (not that
we would want to yet).

Summary:
The boolean lock domain is simple and surprisingly effective.
But it's starting to cause false positives in the case where locks are nested.
Releasing the inner lock also releases the outer lock.
This diff introduces a new locks domain: a map of locks (access paths) to a bounded count representing an underapproximation of the number of times the lock has been acquired.
For now, we just use a single dummy access path to represent all locks (and thus a count actually would have been sufficiently expressive; we don't need the map yet).
But I'm planning to remove this limitation in a follow-up by refactoring the lock models to give us an access path.
Knowing the names of locks could be useful for error messages and suggesting fixes.

Summary:
Previously, we could understand than an access was safe either because it was possibly owned or protected by a thread/lock, but not both. If an access was both protected by a lock and rooted in a paramer (i.e., possibly owned), we would forget the ownership part of the precondition and remember only the lock bit. This leads to false positives in cases where an access protected by a lock is owned, but another unowned access to the same memory is not protected by a lock (see the new `unownedLockedWriteOk` E2E test for an example).
This diff makes access safety conditions disjunctive so we can simultaneously track whether an access is owned and whether an access is protected by a thread/lock. This will fix false positives like the one explained in T24015160.

We add the verification of this constraint to the normalization of sigma.

Summary: Filtering the defined procedure at this level is not necessary. This check already happens when running the analysis in Ondemand. This could also cause flakiness if the "definedness" here does not agree with the check done in Ondemand. The fact that the analysis of a procedure is triggered from the top-level iteration or on-demand when analyzing another procedure is not deterministic.
