Summary:
It is definitely useful to collect information about how long the analysis of every procedure takes. It allows to detect and focus on outliers when trying to improve performance. However, this kind of information could be collected using a standard logging mechanism and does not need to be stored within the analysis artifacts.
I intend to add some form of similar logging in the context of #16348004 once we can get every analysis procedure analyzed through the `Ondemand` module. In this case, it would be easy to have a single place to log how does the analysis of a procedure take.

Summary:
This option is not needed anymore as it was introduced to counter an uncovered
perf issue with creating human readable reports. The perf issue has been
addressed.
Instead of this option, one can use `infer --report-hook /bin/true ...` to
disable reporting. However, right now the Buck integration doesn't honor it so
this would need to be fixed to be a true equivalent of `--disable-bug-list`.

Summary:
This makes sure that one can run `./build-infer.sh` then `make`. Otherwise it's
not always clear what one should do to recompile infer, eg when `make` will
work and when `./build-infer.sh` should be used instead, in particular when the
user doesn't have opam configured for her terminal.

Summary:
Changes every checker to take a summary as parameter and return the updated summary to the next checker. Since several operations, like `Reporting.log_*` are modifying the summary in memory by loading them from the in-memory cache of summaries, we currently need to rely on `Specs.get_summary_unsafe` to return the updated version of the summary.
This diff allows to change the API of `Reporting` to take a summary as input and progressively remove all the calls `Specs.get_summary_unsafe` independently from adding the possibility to run several checkers at the same time. The final objective to have every checker just passing around the summary of the procedure being analyzed, and having the in-memory cache only use to store the summaries of the callees.

Summary:
Procnames files are now reversed qualifier lists with `#` as separator (instead of `::` which needs to be escaped in bash).
Because of the mechanism that is used to obtain qualifiers, it also affects naming for ObjC classes.
Examples:
```
std::unique_ptr<int>::get -> get#unique_ptr<int>#std#__MANGLED,...__ // C++ method
folly::split -> split#folly#__MANGLED,..._ // function within namespace
NSNumber numberWithBool: -> numberWithBool:#NSNumber#class // ObjC method
```

Summary:
We want to stop supporting '-multiletter' options altogether in the future as
they are not standard.
For boolean switches, we used to have '-short' for true and '-nshort' for
false, but that second form is necessarily > 1 letters, which doesn't work in
this scheme. Replace these by '-s' for true and '-S' for false.

Summary:
Add a new command-line option `--per-procedure-parallelism`, to change the granularity of parallelism of the analysis from file to procedure.
This is intended for `--reactive` mode where e.g. a single file is changed and the analysis currently uses just one core.
When the option is used, the Makefile mechanism is replaced by using forking instead.
The parent process does as little allocation as possible, to avoid taxing the kernel.
Caveats:
- Not active in Java, (issues with camlzip).
- Not active in checkers, yet.
Example use:
```
infer --reactive --changed-files-index index.txt --per-procedure-parallelism -- analyze
```

Summary:
There was a race in serialization code where a reader could try to deserialize a partially overwritten value.
Here we use a `file.lock` to synchronize the writers, while the readers are not synchronized.
The atomic `rename` is used to move `file.lock` to `file` and make it available to readers.
Since `rename` is atomic, readers should see possibly stale, but not corrupted, data.

When both an unprotected write and a read/write race emanate from the same line,
