Summary:public
In Python 2, `shutil.rmtree()`, `os.walk()`, `os.path.join()`, etc. are not
happy when the locale cannot decode the filenames they have to deal with.
Decrease the likelihood of this happening by making the file names generated by
infer ascii-only.
Also ignore character decoding errors optimistically when reading the json
report file.
Add tests that we are able to run the analysis and report the bug on a function
with a utf8 name, and that we are able to remove the previous results
directory.

Summary:public
The option -merge_captured specifies that this is merging the results of capture
using the buck integration. The file specifying the targets is read from `infer-out/infer-deps.txt`.
Each dependency specifies a path in buck-out for one target:
where the results directory after capture is.
The option triggers a merge of the results directories into infer-out.
The merge consists in making a virtual copy, where each file in a
target in `buck-out` gets virtually copied into infer-out by making
one symbolic link per file.
There is a mechanism to detect when the capture of a target has already
been copied: when each source file already exists at the destination.
There's also an option `-modified_targets modified_targets.txt`.
If a target is listed in `modified_targets.txt`, this will force a new creation of links
for that target, whether those links exist or not.

Assert false have been observed in Procname when analyzing some C projects.
This diff changes the Procname API to make it safe for Java: the java functions in the module don't assert false now. This takes care of the errors observed in C projects.
The new API forces changes throughout the codebase. In particular, the constant propagation module was making assumptions that it would only be executed on Java code, triggering assert false on C. Now it is safe.
For the remaining functions in the Procname module, those for other languages, a special assert false in Utils is used to print stack traces. This is for future debugging.

Lazy dynamic dispatch handling works as follows:
Assuming a call of the form:
foo(a);
where the static type of `a` is `A`. If during the symbolic execution, the dynamic type of the variable `a` is `B` where `B <: A`, then we create on-demand a copy `foo(B)` of `foo(A)` where all the uses of the typed parameter `a` are replaced with a parameter of type `B`. Especially, if `foo` contains virtual call, say `get` where `a` is the receiver, then the call gets redirected to the overridden method in `B`, which simulates the runtime behavior of Java.
This lazy dynamic dispatch mode is only turn on for the tracing mode for now in order to avoid conflicts with sblackshear's approach for sound dynamic dispatch.

Before this diff, the checker was collecting in a bottom-up fashion all possible call trees from `PerforamanceCritical`-annotated methods to `Expensive`-annotated ones. With this diff, we just collect the names of the direct transitively expensive callees and compute the expensive call stacks when reporting errors only.

Summary:public We model it as the builtin __instanceof which models the instanceof construct of Java.
The behaviour is the same.

Translate headers every time they are included provided that they are located inside project_root directory.
While this is suboptimal (we might end up translating same header many times), doing it exactly once
is hard due to parallel compilation and template instantiations

Is seems that automatically inheriting annotations like `PerformanceCritical` or `NoAllocation` is the right thing to do in general. Otherwise, we need to enforce sub-typing rules which in the best case just adds a little bit of documentation, but could miss important issues when the code is not fully annotated. I am simplifying this part to avoid adding boilerplate code for the `NoAllocation` case.

Type-based resolution of fields, constructors, etc. can be ambiguous if
types are not principal. Compile with -principal and enable warnings 18

Avoid problems of overwriting good type information with incomplete information
when type declaration happens after its complete definition.
The solution is that we will only time we *update* type information is
when struct declaration has definition as well (which should happen once)

The inductive list predicate was not firing during abstraction because of a type mismatch between C and Java. In Java, the second parameter of the `Sil.Sizeof` constructor is always `Sil.Subtype.exact` in C but is `Sil.Subtype.subtypes` in Java. This diff fixes the confution by comparing the `Sil` types only instead of the type expressions.

The analysis of the Buck project was failing because this script converts the aliases into their expanded target names. It turns out that for Buck, the name of the command is `buck` and the name of the alias is also `buck`, which led to conflicts. This is now fixed by only replacing the targets in the part of the command line that is after `build` in `buck build ...`
