Summary:
All tests were redirecting `stderr` into duplicates.txt which made it much harder to see other error messages in stderr (such as uncaught exceptions).
To mitigate it, write duplicates to separate file and don't redirect `stderr` to another file.

Summary:
One limitation of Eradicate is that certain nullability patterns are not expressible using simply the `Nullable` annotation.
One such pattern is using the knowledge that a function returns null when passed null, but returns an object otherwise.
The annotation `PropagatesNullable` is a variant of `Nullable` applied to parameters when their value propagates to the return value.
A method annotated
```
B m(PropagatesNullable A x) { return x == null ? x : B(x); }
```
indicates that `m` returns null if `x` is null, or an object of class `B` if the argument is not null.
Examples with multiple parameters are in the test cases.
This diff builds some infrastructure for annotation transformers: the example above represents the identity function on nullability annotations.

Before, `trace_of_pname` only grabbed unprotected writes from the summary, so the traces ending in an unprotected read were truncated.

Summary:
Two issues in the previous code:
1. We'd just tack on `#compilation-database` so if there already are `#flavors`
in a Buck target then we get a malformed `#flavors#compilation-database`
instead of `#flavors,compilation-database`. There's already code to deal
with that for other flavors (`#infer-capture-all`), so extend and reuse that.
2. The code didn't work if there are spaces in target names (sigh). Harden the
code a bit so that it works. Unfortunately Buck doesn't escape spaces at all
in its `buck targets --show-output` output, so the parsing still relies on
there being no spaces in flavors to work correctly. Sample output:
```
$ buck targets --show-full-output //clang_compilation_database:Hel\ lo#compilation-database
Not using buckd because watchman isn't installed.

```
Also, some code in codetoanalyze/clang-compilation-database/ didn't compile, so
fix that.

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:
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.

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

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.
