Summary:
`Errlog` will merge similar issues (same severity, name, description) reported at the same location, so let's make sure the locaiton is mandatory.
Issues:
- errors happening in `Ondemand` still use the `State` which makes sense only for biabduction and eradicate
- a case of `NullabilitySuggest` didn't have a location, I did my best to patch it but I'm sure the location could be more precise

This works by setting up a worker pool (as before) that waits to receive jobs
(not as before: we used to fork for each new job). Unix pipes are used for
communication.
The new worker pool can be used to experiment with other concurrency models,
such as reviving per-procedure-parallelism, or making sure each procedure is
analysed only once.
Perf tests indicate that this version is no slower than the previous one,
either on laptops or devserver: about 3% worse user time but ~40% better system time.
This new version forks <jobs> processes whereas the previous version would
fork `O(number of source files)` times.

would need a second process to do that).

Summary:
As far as I can tell nothing uses it and it is ignored by the matching engine:
the "parameters" arguments are collected from config options but never actually
used for matching.

Summary:
- During the symbolic execution stage of the backend, Infer will log detailed stats about procedure calls
- Logging is accomplished directly within symExec/Tabulation
- call_result type is moved to tabulation.ml
CallStats was a broken module that allocated a lot of useless memory. Now, Specs.CallStats and InferPrint.CallsCsv as well as the Calls report kind in InferPrint no longer exist.
