Summary:
Before: the trace would explain how a value was invalidated and
accessed, but not how the value that was invalidated had been
constructed.
Now: `PulseTrace.t` records breadcrumbs of how the value was constructed
in addition to the interproc "action" trace leading to the invalidation
or access action.
Concretely:
```
void bad(X &x) {
X *y = x;
X *z = x;
delete y;
access(z);
}
```
will produce the trace:
Invalidation part:
y = x
delete y
Access part:
z = x
access(z)
access to z->f inside of access(z)
Before this diff the "Access part" would be missing the "z = x" part of
the trace, so it might be confusing why `z` has anything to do with `y`.
However, such "breadcrumbs" are not recorded in the inter-procedural
part, only the sequence of calls is. This is a trade-off for simplicity,
maybe it's enough for developers maybe it isn't, we'll find out later.

Summary:
Enabling starvation by default (D15158597) makes infer double report racerd
issues in these tests. The reason seems to be that both racerd and starvation
use `IssueLog` to record issues, so racerd records its issues there (using side
effects), then starvation adds its own (empty) set of issues and reports
whatever is there again. Since nothing cleans up the IssueLog in the middle,
racerd issues get reported twice: once as racerd issues and the other as
starvation issues.
Let's fix this later, for now just unbreak the test itself.

Summary:
A more dynamic scheduling scheme will potentially run into the situation where no new work packets can be scheduled, but more work will be possible to schedule in the future, perhaps when some dependent work packet finishes being analysed.
The current implementation prevents that, as it expects that if a worker goes idle, it stays idle.
The changes here address this in two parts:
- the `select` call is always given a finite timeout. If given an infinite timeout, we will not be able to poll the task generator for more work, where none were previously possible.
- when the `select` call times out without updates, check if there is an idle child, and if so if the task generator has more work right now.
See also ProcessPool.mli for comments.

Summary:
Before moving to any kind of non-trivial scheduling, we need to change the Tasks interface.
In particular, it's too restrictive to expect that the tasks to be scheduled are provided as a list before starting execution. For example, dynamic scheduling does not fit the bill here. Also, the list expectation means all scheduling work has to be done up front.
The solution here is to move to a `Sequence`-like interface with one difference:
- The function returning the next task expects a task option argument. That argument is the task that was just finished (if any) by the worker expecting new work. This will be useful for things like task dependencies (for instance, a procedure has been analysed, and can be marked so).

TOPL properties are essentially automata, which will be modeled as a set
of procedures. The code-to-analyze makes calls into these procedures,
thereby driving the automaton. In this commit, these calls do not do
anything. The point is to prepare the hook-up mechanism.
