That test wasn't hooked up to `make test` and so regressed at some
unknown time in the past. Just recording the new state of things for

Summary:
`infer_events` table is a key-value storage that also have list of fields common for entire infer run.
Infer should be agnostic of many of such fields (e.g. diff number).
Hence we will pass such extra fields through CI.
Note that only "normals" (strings in scuba terminology) are currently supported.
Reason being: most of things that are technically ints (like IDs) should actually be normals (because average etc does not make sense for them; and group by, in contrast, does).

Summary: There can be A LOT of procedures -- currently we log two lines (started/done) for each one, when doing call graph scheduling. This leads to ridiculously long log files. Switch to only log these messages in the log file and only if we are verbose logging.

Summary:
Thanks to the newly added `StarField`, path length is better controlled before ondemand is used.
Hence there is no need to (unsoundly) canonicalize paths then anymore.

This messes with the deduplication heuristic when templated function
names show up in the error messages, since the heuristic demands that
the error messages are the same.

Summary:
Some edge case involving casting field pointers to the structure type itself generated arbitrarily long paths when used in a loop.
Without changing the widening, this diff avoids repetitions of fields in paths by abstracting them with a star.
E.g. `x.a.b.c.b` will become `x.a.b.c*.b`, and so will `x.a.b.c.a.b`, `x.a.b.c.c.b`, or `x.a.b.c.b.b`.

I was wondering what were the empty sessions and why inferbo was running twice.
Answer: the empty sessions were 'compute pre' and the second run of inferbo was the narrowing phase.

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.
