Summary:
When trying to add annotations to code examples, Javadoc gets confused about `@` sign and there's no good way to fix it so it's both OK to read as a comment in the editor and as a Javadoc HTML, no matter what combination of <code>/<pre>/{code} or escaping you use.
Here we prioritise ability to read the code comment from the editor and therefore the comments are detached from annotations.

Summary:
Now when typechecking a class `A` marked with `Nullsafe(LOCAL)`,
classes from trusted list are properly recognized and nullability of
method params and return value are refined to `LocallyCheckedNonnull`
in a context of class `A`.
NOTE: refininng nullability when **accessing fields** on trusted classes
is **not implemented yet**, because the whole business of handling fields
in nullsafe is somewhat convoluted. This should not be a huge issue
though, since in Java fields are commonly accessed via getters any
way.

This ignores the error memory status (e.g. when condition expression is evaluated to bottom), in
order to keep analyze following code.
```
if ( e ) // e is evaluated to bottom due to a problem of Inferbo {

Summary:
This will help making error reporting more actionable.
Often methods that are nullable in general (like View.findViewById) are used as not-nullable due to app-invariants. In such cases suggesting a non-nullable alternative that does an assertion under the hood makes the error report more actionable and provides necessary guidance with respect to coding best practices
Follow up will include adding more methods to models.
If this goes well, we might support it in user-defined area (nullability
repository)

Summary: Count the time used by the `RestartScheduler` for analysis (useful) and the time wasted because a a worker was not able to take a lock to have a metric to compare different versions of the scheduler. The wasted time is not actually count but it can be calculated by substracting useful time from the total time. This was implemented like these to avoid substractions that may make the floating point calculations more complicated.

Summary: When a worker fails because it can't a get the lock of a `Procname` it will include it in the exception that it throws so the `RestartScheduler` can record it as a dependency. Then when scheduling a new work item from `RestartScheduler.next` it will check if this dependency is already met, if it isn't it will not schedule the `Procname` yet.

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:
We need to be able to differentiate `UncheckedNonnull`s in internal vs
third-party code. Previously, those were under one `UncheckedNonnull`
nullability which led to hacks for optmistic third-party parameter
checks in `eradicateChecks.ml` and lack of third-party enforcement in
`Nullsafe(LOCAL, trust=all)` mode (i.e. we want to trust internal
unchecked code, but don't want to trust unvetted third-party).
Now such values are properly modelled and can be accounted for
regularly within rules.
Also, various whitelists are refactored using
`Nullability.is_considered_nonnull ~nullsafe_mode nullability`.
`ErrorRenderingUtils` became a tad more convoluted, but oh well, one
step at a time.

Use a record of package, class name to store (qualified) Java class names. This saves the round trip of concatenating then splitting again, etc, as well as saves some memory in the type environment as now the package paths can be shared across classes of the same package (about 10% in tests).
Also remove some unfortunate APIs.

Summary:
Currently the free variables of the equality relation of a formula are
contained in the free variables of the rest of the formula, so Sh.fv
ignores them. Propagating equality facts across the star-or structure
of a formula, as necessary for quantifier elimination, breaks this
invariant. Some use cases, such as detecting which variables survive
applying a witness substitution, need to ignore the variables that
appear in the equality relation. This diff adds an argument to
conditionally ignore the variables in the equality relations.
