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:
In order to test cost analysis results, currently we rely on having an arbitrary cost threshold (200) and report issues that exceed this cost. For instance, a cost of 201 is considered expensive and reported as `EXPENSIVE_EXECUTION_TIME` issue in cost tests.
This means, if we change the cost analysis in a slight way that results in some constant cost increase under 200, we wouldn't able to detect it. I find this unsatisfactory and somewhat hacky.
This diff adds the ability to write the result of `costs-report.json` into a separate `cost-issues.exp` and then compare the actual costs (not only than relying on this arbitrary threshold reporting mechanism).

Summary:
Because in the real semantics CFRelease can be used more than once, and also the variables can be used after CFRelease in general, modelling this as `free` causes many `USE_AFTER_FREE` errors. Now we change the model to not add the `Invalid CFree` attribute, but to just remove the `Allocated` attribute. So we can model memory leaks in the simple case of `Create` and not `CFRelease` before going out of scope, but we avoid the `USE_AFTER_FREE`.
Since the model for CFRelease now diverges from free, changed the command line option for modelling to `pulse-model-release-pattern`.

This diff is doing three things:

file level analysis. Here we use this API in nullsafe, so now we can
analyze things on file-level, not only in proc-level like it was before!
2. Introduces a class-level analysis. For Nullsafe purposes, file is not
an interesting granularity, but we want to analyze a lot of things on
file level. Interesting part here is anonymous classes and how we link
them to their corresponding user-defined classes.
3. Introduces a first (yet to be improved) implementation of class-level
analysis. Namely it is "meta-issues" that tell what is going with class
on high level. For now these are two primitive issues, and we will
refine them in follow up diffs. They are disabled by default.
Follow ups include:
1. Refining semantics of meta-issues.
2. Adding other issues that we could not analyze before or analyzed not
user friendly. Most importantly, we will use it to improve reporting for
FIELD NOT INITIALIZED, which is not very user friendly exactly because
of lack of class-level aggregation.

Summary:
These were not used (and were actually activated byt the same config
param). They both are in experimental stage that never reached maturity.
Since the team does not have immediate plans to work on ObjC nullability
checker; and since "eradicate" (now known as nullsafe) is the main
solution for Java, removing it is sensible.

This diff renames `ZERO_XXX` issues to more appropriately named and descriptive
`XXX_UNREACHABLE_AT_EXIT` and replaces bottom with
unreachable in cost kinds and issues.

Summary:
The `--continue-analysis` option enables continuing analysis after more targets are captured by
`--continue`. For example,
```
$ infer capture -- buck build tgt1
$ infer analyze --merge
$ infer capture --continue -- bucck build tgt2
$ infer analyze --merge --continue-analyze
```
In the last analysis, it reuses the analysis results of `tgt1` from the previous analysis. If
`tgt1` and `tgt2` have a same dependency to a library, the analysis results of the library is also
reused.

Summary:
Add support for nullsafe mode with `trust=all` and `trust=none` a case
with a specific trust list is not supported yet and needs to be
implemented separately.
Tests introduce one unexpected
`ERADICATE_INCONSISTENT_SUBCLASS_PARAMETER_ANNOTATION` issue which
complains about `this` having incorrect nullability; it is a bug and
needs to be fixed separately.
