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).

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.

We can already tell that a summary cannot be applied by raising
`Contradiction`, so use this mechanism to stop applying a summary if the
number of formals doesn't match the number of actuals provided.
Previously we would return an option type and `None` in case of
mismatch, on top of the `raise Contradiction` mechanism (used for
aliasing and arithmetic contradictions).
This changes the behaviour of pulse in this case: before we would skip
over the function call, but now we stop the analysis.

Summary:
Previous implementation supported only stringy params (strings and
stringified bools). Current one exposes a proper variant `Annot.t`,
with support for all possible param values in Java except
numbers (more on that below).
This change is required for implementing `Nullsafe(LOCAL)` as the
annotation used to specify nullsafe behaviour has a more complex
structure than what we've dealt with before.
**Why support for number values was not added**: supporting numbers
requires using `int64`. Unfortunately, adding another variant `Vnum
int64` to `Annot.t` causes a runtime failure on assert in
`MaximumSharing.ml:133`. It seems that it might be enough to flip
`fail_on_nonstring` from `true` to `false`, but since this would
require additional testing and is not required for my case, I'll leave
checking this to whoever needs to use numeric annot params in future.
